   worked fine no feedback. Maybe the other guys did something wrong like running rca next to or over power wires no issues here.

   Needed an amplifier to play holiday music out of 4 speakers, on a firetruck, from an mp3 player. It worked like a charm. Plenty loud enough for Santa & his helpers.

   When I first bought it I installed it on my Chevy Tahoe. It sounded crap! The Clarion radio I installed had more power than this amp. Then I installed 2 other amps replacing this one, and none of those sounded OK. I took away the amp installed on my Jetta, which sounded AMAZING, with the same speakers and didn’t even close to the way it sounded on the Jetta.
   
   So I decided it was something with the acoustic on the Tahoe.
   
   I bought another SUV and something happened to the amp I was installing, didn’t wanted to power, so, with all cables running through the SUV and the speakers installed, pair of Kenwood 6×9 400 watts 4-way, and a Pyle 10″ sub, just curious, I decided to install this Pyramid amp just to make at least some noise in my SUV, thinking it was going to sound crap.
   
   What a surprise!
   
   This small amp, really moved the speakers and sub! Sound is great, way ahead of expected.
   
   Only con of this amp, it’s that it’s not bridgeable. But even do this, I bridged it to give it more power to the sub, and gave little more, and has functioned perfect for about 2 months now.

   It’s a cheapo. I don’t recommend it, as it reproduces a substantial amount of electrical (alternator) noise.

   not a very good product. The most electrical noise I have ever heard from an amp. These amps shouldn’t be on the market.
