These guidelines mean your amplifier's output power ratings are REAL POWER numbers, not inflated marketing ratings. Class bd Rockford Fosgate bd topology is a revolutionary patented design, integrating a technology that is more efficient than typical class AB and has lower distortion than class D designs. POWER bd amplifiers are 75-80% efficient vs. 20-60% efficient class ab amplifiers. What does that mean? More power from your amplifier with less drain on your vehicles electrical and charging system. Constant Power Music and speakers have a dynamic relationship. As the frequency of music varies, so does the impedance of the speaker. This patent pending technology gives the amplifier the ability to instantaneously deliver its maximum output power to the speaker without regard to its varying impedance while still maintaining its high-efficiency and thermal performance. Differential Inputs Differential input circuitry measures the voltage of both the (+) and (-) input signal. The circuitry subtracts the voltage common to both conductors (noise) resulting in only the clean signal. This allows only clean signal to enter the amplifier. DSM DSM utilize 1% tight-tolerances improving efficiency of the circuit, decreases cross-talk from other discrete components and lowers operating temperature. Dynamic Thermal Management Heat is often inefficiently dissipated across a heatsink causing "hot spots". Rockford Fosgate engineers have developed an award winning cooling design called DTM. This patent pending design seamlessly manages the output of power supply temperatures, while evenly distributing the excess heat across the entire amplifier. MEHSA3 MEHSA3 (Maximum Efficiency Heat Sink Application--gen. 3) reduces MOSFET temperatures, lowers distortion, increases durability and prolongs the output device life span. Punch EQ2 In the early 70's, Jim Fosgate studied the acoustical properties of automobiles. Utilizing a real-time analyzer and pink noise, he would graph out the acoustical characteristics of each car he tested. Jim discovered three problems that were common to all cars: a midbass hump between 100-275Hz, a steep roll-off of high frequencies from 2kHz up to 20kHz, and reduced bass response below 50Hz. The Punch EQ on-board equalization circuit helps correct for these acoustical deficiencies in the listening environment. When set to Low-Pass(LP) operation, it becomes a variable Bass Boost. When set to High-Pass (HP) operation, it acts as a variable Mid-Bass and Treble Boost. When set to All Pass (AP) operation, both Bass and Treble frequencies are boosted.

Rockford is one of the oldest and most respected brands in car audio history, and has been pumping out high quality, great-sounding gear since 1973. By pioneering ideas like the Punch EQ (boosting frequencies below 45Hz and above 20Khz for improved in-car music response) and using MOSFET circuitry to power in-car amplifiers, Rockford Fosgate paved the way for modern in-car electronics and hasn't slowed down since. The P400-4 features an ultra-small small footprint, and a clean, simple design that looks great no matter where it's installed. Dynamic Thermal Management ensures even heat dissipation across the entire heatsink for maximum efficiency and cooling. Rockford Fosgate amplifiers combine raw, clean power, with sleek, smart designs that are easy to install and look great in any car. All Rockford amps are CES-2006 compliant, which means the power listed is the actual power delivered, and each amp includes a birth certificate to prove it. But don't let the small size fool you; this petite powerhouse, which can easily fit under any seat, packs quite a punch! The P400-4 is the perfect companion for two pairs of coaxial or component speakers, or a pair of speakers and a simple subwoofer system. The P400-4 delivers 50 watts of clean power to for channels in stereo mode, or 200 watts per channel when bridged down to a two channel amp. But what exactly sets a Rockford Fosgate amplifier apart from the competition? Plenty. Keeping Things Clean and Cool The amplifier's job is to produce power, and lots of it. But a side effect of creating power is heat, and that is an electronic component's worst enemy. Rockford tackles this problem by incorporating a cast aluminum heat sink, Dynamic Thermal Management, and MEHSA³ technology to every amplifier, resulting in a significant reduction of the amplifier's operating temperature. The cast aluminum heat sink surrounds three of the four sides of the amplifier's circuit board, which maximizes the cooling surface area, and since the heat sink is cast it offers 30% better cooling ability over extruded designs. When combined with Rockford's patented Dynamic Thermal Management (DTM), cooling efficiency is taken one step further. DTM distributes heat evenly across the heat sink where other heat sink designs can create dangerous hot spots in the amplifier. Rockford also developed MEHSA³ technology for the MOSFET (metal–oxide–semiconductor field-effect transistor) power transistors. MEHSA³ (Maximum Efficiency Heat Sink Application- Third Generation) maximizes heat transfer from the MOSFETs to the heat sink for up to five times better heat transfer. By keeping the internal components cool, the amplifier maximizes efficiency, produces more power, and reduces distortion for increased sound quality. Not only does the P400-4 produce lots of clean power, it also delivers exceptional sound quality. Differential input circuitry measures the positive and negative input signal as it enters the amp and subtracts the voltage common to both conductors (noise), resulting in a crisp, clean signal for maximum sound quality. The use of TRANS-ana circuitry, borrowed from pro-audio company, Hafler, also adds to the sound quality recipe. The TRANS-ana circuit simplifies the audio signal and allows it to travel through the amplifier as a low voltage signal before it reaches the amplification stage. This improves the sound quality of the signal, delivers cleaner performance, and improved reliability. The P400-4's TO-247 MOSFET power transistors offer 60% more metal tab area than the industry standard TO-220 MOSFETs, which means more power, better cooling, and improved sound quality. Once the signal reaches the amplification stage, it's greeted by much beefier MOSFETs than what is traditionally used in most amplifiers. Rockford uses TO-247 MOSFETs compared to the somewhat standard and less efficient TO-220 MOSFETs. TO-247s offer 60% more metal tab area, which means more power capacity, better heat dissipation, and lower impedance capability. In other words, these things produce some serious power with very little effort. Sound Shaping and Equalization Upgrading speakers and adding subwoofers will always improve your sound system, but in order to maximize how well the speaker performs requires a bit of equalization and sound shaping. Door and dash speakers can play a pretty broad range of frequencies, but realistically cannot produce the ultra-low frequencies that a subwoofer is designed to produce. Just the opposite is true for a subwoofer. It cannot produce mid or high frequencies well; its job is to pump out gut-punching bass. To make sure your speakers are working at their maximum efficiency, Rockford incorporated a fully variable 12db high-pass and low-pass crossover into the 400-4. With a twist of the dial, the high-pass crossover can be adjusted to eliminate any frequencies below a certain point between 50Hz and 500Hz. If using the 400-4 for a subwoofer system, switch on the low-pass crossover and adjust the crossover to eliminate higher frequencies, adjustable between 50HZ and 500Hz. The Punch EQ can be tweaked to deliver up to an 18dB increase at 45Hz for subwoofers, or up to a 12dB increase at 12kHz for speakers. This improves overall sound quality and overcomes audio response problems common to the automotive environment. Rockford Fosgate built a reputation around the Punch EQ, which is incorporated into their Punch amplifiers, and allows the amp to better shape the sound quality of your speaker or subwoofer system. When using the high-pass crossover, the Punch EQ can boost high frequencies above 12kHz anywhere from 0-12dB. This frequency range is often lost to road noise and other factors, and the Punch EQ allows you to dial up that range for perfect sound. If the low-pass filter is on, the Punch EQ can add a bit of boost (up to 18dB) to the 45Hz frequency range. This gives you the ability to dial in a little extra rib-rattling bass to your music that can be lost due to the compact size of most car interiors. Making the Connection All controls and connections are located on one edge of the amplifier, making it easy to access all controls and guaranteeing an easy, clutter-free installation. The P400-4 will accept up to 4-gauge power and ground wire, and all connections are neatly housed in c-clamp type connectors that terminate inside the amp's chassis. This adds a cleaner appearance to your install and ensures no "fly-away" wires can stray to other terminals causing possible shorts. All connections are recessed into the amplifier's chassis and located on the bottom edge of the P400-4, for a clean, uncluttered install that looks great in any car. Speaker connections also use a similar clean audiophile design, and will accept up to 12-gauge wire for maximum signal transfer to your speakers or subs. The amp features a single RCA connection flush with the amp's chassis, further enhancing the overall clean appearance. An RJ-45 jack is for connecting an optional remote-mounted Punch EQ control and is located next to the crossover and Punch EQ controls. The remote PEQ controller can be installed up front and within easy reach to give you on-the-fly control of your Punch EQ settings. Pushing Power The P400-4 is a flexible amplifier and is stable at two-ohms. This amp is perfect for powering front and rear speakers in four-channel mode, delivering 50 watts of clean power to each speaker. Or you can mix things up a bit and use the P400-4 to drive two front coaxial or component speakers at 50 watts RMS and bridge the rear channel to deliver 200 watts to a subwoofer.

Rockford test each amplifier is that they sell and then put the numbers in the box to the amp. It P4004 at 50 watts x 4 at 4 ohms will be evaluated, was shown the one I got off 93 watt x 4 at 4 ohms. This amp is extremely quiet, you hear nothing when between songs. The P4004 is combined with an Alpine CDA-9885 receiver, a lovely combination. The Rockford has really impressed me, I would recommend it. 4 of 4 people found the following review helpful. The usual excellent quality of Rockford Fosgate Rockford Scott Carpenter consistently underestimated amplifiers. The refresh rate has been installed as part of an overall system. Along with this came the JVC KW-XR810 head unit and Rockford Fosgate 12 "subwoofers. It was in a 2003 RAV4 Toypta, instead of an old (2 years old) Pioneer headunit. I had replaced the stock speakers with Infinity Reference 65 "speakers front and rear. The sound was loud and muddy, and I do not think it could be better people, without doing some serious noise reduction and tuning. I was completely wrong. This system changed my Toyota. The Infinity speakers come alive. The peaks are sharp and clear, the mids are very present but not overwhelming, and a low (I called the high pass filter to the subwoofer works 6.5 "speaker just can not) are solid. The subwoofer is not overwhelming, but it could be. I have the response to be flat, without the subwoofer to drown everything else. I've played everything from Bach to Dirty Vegas for Nine Inch Nails. It seems incredible. Before I was on the subwoofer, it sounded incredible, and just better. I've also linked it to an old Kenwood Sirius tuner, I've had a lifetime subscription for about 8 years ago and which also sounds good - just not as good as a new CD I've done errands to run today, just so I could spend more time with my car. It seems that good. I knew that my old head unit was under-powered speaker, but I had no idea that we could put a good amp to change things so much. 3 of 3 people found this review helpful.

These guidelines mean your amplifier's output power ratings are REAL POWER numbers, not inflated marketing ratings. Class bd Rockford Fosgate bd topology is a revolutionary patented design, integrating a technology that is more efficient than typical class AB and has lower distortion than class D designs. POWER bd amplifiers are 75-80% efficient vs. 20-60% efficient class ab amplifiers. What does that mean? More power from your amplifier with less drain on your vehicles electrical and charging system. Differential Inputs Differential input circuitry measures the voltage of both the (+) and (-) input signal. The circuitry subtracts the voltage common to both conductors (noise) resulting in only the clean signal. This allows only clean signal to enter the amplifier. DSM DSM utilize 1% tight-tolerances improving efficiency of the circuit, decreases cross-talk from other discrete components and lowers operating temperature. Dynamic Thermal Management Heat is often inefficiently dissipated across a heatsink causing "hot spots". Rockford Fosgate engineers have developed an award winning cooling design called DTM. This patent pending design seamlessly manages the output of power supply temperatures, while evenly distributing the excess heat across the entire amplifier. MEHSA3 MEHSA3 (Maximum Efficiency Heat Sink Application--gen. 3) reduces MOSFET temperatures, lowers distortion, increases durability and prolongs the output device life span. NOMAD NOMAD (Non Multiplying Advanced Decision) is a "real time" analog computer that protects your amplifier from shorting speaker wires and dangerously low speaker impedances. Punch EQ2 In the early 70's, Jim Fosgate studied the acoustical properties of automobiles. Utilizing a real-time analyzer and pink noise, he would graph out the acoustical characteristics of each car he tested. Jim discovered three problems that were common to all cars: a midbass hump between 100-275Hz, a steep roll-off of high frequencies from 2kHz up to 20kHz, and reduced bass response below 50Hz. The Punch EQ on-board equalization circuit helps correct for these acoustical deficiencies in the listening environment. When set to Low-Pass(LP) operation, it becomes a variable Bass Boost. When set to High-Pass (HP) operation, it acts as a variable Mid-Bass and Treble Boost. When set to All Pass (AP) operation, both Bass and Treble frequencies are boosted.

Rockford is one of the oldest and most respected brands in car audio history, and has been pumping out high quality, great-sounding gear since 1973. By pioneering ideas like the Punch EQ (boosting frequencies below 45Hz and above 20Khz for improved in-car music response) and using MOSFET circuitry to power in-car amplifiers, Rockford Fosgate paved the way for modern in-car electronics and hasn't slowed down since. The P1000-1BD features an ultra-small small footprint, and clean, simple design that looks great no matter where it's installed. Dynamic Thermal Management ensures even heat dissipation across the entire heatsink for maximum efficiency and cooling. Rockford Fosgate amplifiers combine raw, clean power, with sleek, smart designs that are easy to install and look great in any car. All Rockford amps are CES-2006 compliant, which means the power listed is the actual power delivered, and each amp includes a birth certificate to prove it. But don't let the small size fool you; this petite powerhouse, which can easily fit under any seat, packs quite a punch! The P1000-1BD features Rockford's patented Class-BD circuitry and is designed specifically to drive subwoofers with maximum clean power. Flexibility and efficiency are what the BD series amps are all about, handling subwoofer loads from 4-Ohms all the way down to a 1-Ohm. So whether you're powering a single 4-Ohm sub or a quartet or subwoofers, the P1000-1BD will rock the house. But what exactly sets a Rockford Fosgate amplifier apart from the competition? Plenty. Keeping Things Clean and Cool The amplifier's job is to produce power, and lots of it. But a side effect of creating power is heat, and that is an electronic component's worst enemy. Rockford tackles this problem by incorporating a cast aluminum heat sink, Dynamic Thermal Management, and MEHSA³ technology to every amplifier, resulting in a significant reduction of the amplifier's operating temperature. The cast aluminum heat sink surrounds three of the four sides of the amplifier's circuit board, which maximizes the cooling surface area, and since the heat sink is cast it offers 30% better cooling ability over extruded designs. When combined with Rockford's patented Dynamic Thermal Management (DTM), cooling efficiency is taken one step further. DTM distributes heat evenly across the heat sink where other heat sink designs can create dangerous hot spots in the amplifier. Rockford also developed MEHSA³ technology for the MOSFET (metal–oxide–semiconductor field-effect transistor) power transistors. MEHSA³ (Maximum Efficiency Heat Sink Application- Third Generation) maximizes heat transfer from the MOSFETs to the heat sink for up to five times better heat transfer. By keeping the internal components cool, the amplifier maximizes efficiency, produces more power, and reduces distortion for increased sound quality. Not only does the P1000-1BD produce lots of clean power, it also delivers exceptional sound quality. Differential input circuitry measures the positive and negative input signal as it enters the amp and subtracts the voltage common to both conductors (noise), resulting in a crisp, clean signal for maximum sound quality. The use of TRANS-ana circuitry, borrowed from pro-audio company, Hafler, also adds to the sound quality recipe. The TRANS-ana circuit simplifies the audio signal and allows it to travel through the amplifier as a low voltage signal before it reaches the amplification stage. This improves the sound quality of the signal, delivers cleaner performance, and improved reliability. The P1000-1BD's TO-247 MOSFET power transistors offer 60% more metal tab area that the industry standard TO-220 MOSFETs, which means more power, better cooling, and improved sound quality. Once the signal reaches the amplification stage, it's greeted by much beefier MOSFETs than what is traditionally used in most amplifiers. Rockford uses TO-247 MOSFETs compared to the somewhat standard and less efficient TO-220 MOSFETs. TO-247s offer 60% more metal tab area, which means more power capacity, better heat dissipation, and lower impedance capability. In other words, these things produce some serious power with very little effort. Sound Shaping and Equalization Adding subwoofers to your sound system is one of the best ways to improve your sound system. A subwoofer adds depth and realism to your sound system that door and dash speakers simply cannot replicate. But since a subwoofer cannot produce mid or high frequencies well, Rockford incorporated a variable 12db low-pass crossover into the P1000-1BD. With a twist of the dial, the high-pass crossover can be adjusted to eliminate any frequencies below a certain point between 35Hz and 250Hz. The Punch EQ can be adjusted to deliver up to an 18dB increase at 45Hz, improving overall sound quality, and overcoming audio response problems common to the automotive environment. Rockford Fosgate built a reputation around the  Punch EQ, which is incorporated into their Punch amplifiers, and allows the amp to better shape the sound quality of your speaker or subwoofer system. When using the high-pass crossover, the Punch EQ can boost high frequencies above 12kHz anywhere from 0-12dB. This frequency range is often lost to road noise and other factors, and the Punch EQ allows you to dial up that range for perfect sound. If the low-pass filter is on, the Punch EQ can add a bit of boost (up to 18dB) to the 45Hz frequency range. This gives you the ability to dial in a little extra rib-rattling bass to your music that can be lost due to the compact size of most car interiors. Making the Connection All controls and connections are located on one edge of the amplifier, making it easy to access all controls and guaranteeing an easy, clutter-free installation. The P1000-1BD will accept up to 4-gauge power and ground wire, and all connections are neatly housed in c-clamp type connectors that terminate inside the amp's chassis. This adds a cleaner appearance to your install and ensures no "fly-away" wires can stray to other terminals causing possible shorts. All connections are recessed into the amplifier's chassis and located on the bottom edge of the P1000-1BD, for a clean, uncluttered install that looks great in any car. Speaker connections also use a similar clean audiophile design, and will accept up to 8-gauge wire for maximum signal transfer to your subs. The amp features a single RCA connection flush with the amp's chassis, further enhancing the overall clean appearance.RCA jacks are also recessed to the amplifiers chassis. The P1000-1BD has two pairs of RCA jacks, one is the input, the other is a pass-through jack. A pass-through allows easy connection of an additional amplifier without the need of a second set of RCAs run all the way to the front of the car from the second amplifier. This is particularly useful when using the factory radio as the source unit. An RJ-45 jack is located next to the crossover and Punch EQ controls, and for connecting an optional remote-mounted Punch EQ control. The remote PEQ controller can be installed up front and within easy reach to give you on-the-fly control of your Punch EQ settings.

Pushing Power The P1000-1BD is a very flexible amplifier, and is stable down to a 1-ohm load. At 4-ohms, the P1000-1BD will pump out a nice respectable 250 watts. At 2-ohms, the power doubles to 500 watts, perfect for a single monster subwoofer or pair of moderate subwoofers. But drop this amp down to 1-Ohm and prepare to unleash the beast with an amazing 1000 watts RMS. The P1000-1BD is a great amp for upgrades if you need to add more power to your system, but it's also a great building block for designing a monster subwoofer system in steps. The BD's impedance flexibility makes it easy: start with a dual 2-Ohm subwoofer wired to 4-Ohms, and the P1000-1BD will pump out 250 watts. Later, you can add an additional sub of the same model and voice coil configuration, and the P1000-1BD will lay down 250 watts to each sub (500 watts total at 2-Ohms). Flexibility, power, and convenience are what the Rockford BD-series amps are all about. What’s in the Box P1000-1BD amplifier, Installation & operation manual, Warranty
