Customer reviews more useful to 7 of 7 people found this review helpful. exceptional quality for the price Hacker Martin Rojas Do not waste your time looking for other brands. If you want the best quality and the power of your car audio system, get Rockford. I replaced my Sony 600W amplifier 4 for it, and let me tell you, there is no comparison. WI 2120 and filled the speakers have a subwoofer Sony Sony W 400 ... the sound of the speaker is loud and clear (similar to what I was getting the Sony amplifier) ​​... But the sound from my subwoofer is just amazing - and only half the power (the whole car shakes when) ... I highly recommend this product and never return to the custom of brands like Sony or Pioneer amps 4 of 4 people found this review helpful. Beautiful but flawed by a great amp looking StereoInstaller1 What! Construction Taiwanese terminals typically excellent, beautiful landscape controls. The S / N ratio is a bit noisy, but if you listen to piano solos in a car incredibly quiet that you never get the little hiss noticed that I was very impressed with the sound dynamics, but a "cut" (har -dee - harhar) and legal clarity. Vocals were nice and shiny clean dishes well ... SQ was pretty much everywhere. Guitar in particular, was very nice, full and fat. Two problems for this amp IMO, and the first function is really a glaring omission: the high pass filter set to 80Hz. If you are one of the thousands of cars with a smaller front speakers (if your vehicle is nothing less than a total depth of 6.5 driver "for use) makes this amp a very poor choice, unless you're planning an external crossover. This fixed 80Hz crossover could explain the "fat" midbass, but it was certainly not appreciated by 5.25 "speakers in front of the BMW. The second issue is heat. This sleek looking amp does not have sufficient heat dissipation IMO, especially if you plan to run a sub 4-ohm mono, half of the ending (my general setup "Starter") will probably have to do something for the release of heat, especially if amplifier is closed in any way. Strangely, not the largest mono amplifier using this heatsink itself does not seem to have this problem, even on a single 2 ohm load. This series of "Prime" is great looking product with only a few minor errors, and priced very well. 2 of 2 people found this review helpful. Great little amp! By JE If this amp about 6-8 months. Strong little work horse. Can not beat her power "and" price for that matter, to run the 4 speakers. You can use 3 times as much, and need two to do the same trick with other brands. And then you feel 'others' too! It is a sign of proven superior. Everything you need! See all 8 customer reviews ....
