The Nitro BMW-483 amplifier is a really good product. Right after i hooked it up in my 93z28 camaro, i played with the amplifier for like thirty minutes. I was checking all the gains, and crossovers, and the hi crossover sounds really great . Because if you have any experience with sound engineering, on most amplifiers the hi range and mid range is not that good, but i on this one is sounds pretty clear. The lighting on the amplifier was pretty good but one of the features that could of been done was that it flashes with the beat. over all rating on the product. I give it four stars.

Bad one. Don't buy it. Manifactureneed to improve it. Bad sound and a lot of static.

• Please tell us about the quality of the product. Bad

I replaced my fried Rockford Fosgate amp in my '86 911 with this amp. I was worried at first about going with a non-famous brand. My head unit is an Alpine and I have Focal speakers. The base boost on this amp is great. It was exactly what my system needed and I'm impressed as heck. In addition to the great sound, the glowing blue LEDs do make it look like a Flux Capacitor straight out of "Back to the Future". One thing that was confusing at first is that the 4 channels are labeled as channels 1-4, instead of the standard Front/Rear and Front/Back. Perhaps it was just me, but it confused me enough that I had to write down a cheat sheet. My summary: Excellent sound, lots of power, fairly small size, looks cool, and lots of adjustments possible to mold the sound to your needs.

VERY NICE LOOKING AMP GOOD SOUND AND MUCH BETTER PRICE

The Nitro Amp looks like the Flux Capacitor, but it is easy to install and provides the Thump, Thump my truck was lacking. The amp is really easy to adjust and now I have crystal clear sound even when I turn up the volume. I matched the Nitro amp with 12" Kenwood woofers that I bought through Overstock.com and I couldn't be happier. It has greatly improved my commute.

THIS AMP HAS GREAT DEEP BASS SOUND, UNLIKE SOME AMPS WITCH HAVE ALOT OF DISTORTION, WHEN YOU TURN UP THE HIGH LEVEL, THIS AMP BLOWS AWAY ANY OTHER AMP IVE EVER HAD!!!!!!
