  1. Beast 5 Star Review

    Posted by on 11th Nov 2018

    So I decided to buy this amp, and it was one of the last ones before it discontinued, I have this hooked up on 0ga ofc wire, with a D7500 battery. The subs are 2 12’s contraltos wired at 1ohm and I tell you what, this amp is a beast. It supplies POWER. THIS IS THE ONE! It does not run hot. The bass knob that comes with this amp is a bit sensitive, and has a bright blue tho, but that doesn’t matter. POWER IS WHAT MATTERS. A legend that is now discontinued

  5. Mind Boggling Bass!! 5 Star Review

    Posted by on 29th Nov 2016

    I've worked my way up through the ranks of the bc series amps from the 2k to the 3500 and now to the 5500!! There is a reason I've stuck with this brand and series! Absolute powerhouses built tough and ready for everyday ground pounding to competing! If your looking to be dependably loud and support a great company look no further and scoop one of these amps up as fast as you can!!!

  6. Best amp i ever Bought hands down 5 Star Review

    Posted by on 3rd Aug 2016

    I have 2 FI sp4 18's and a crescendo 5500 on each sub. My bass is ridiculous right now. If your looking for a good amp with clean power by the f#%@ing amp you won't be disappointed.

  7. Rock Solid Amp With True Clean Power 5 Star Review

    Posted by on 2nd Sep 2015

    I took this amp to a competition the day after I got it and was playing it for a good amount of time and went to feel it and it wasn't even warm , I HIGHLY recommend this amp A++++++

  8. does what it supposed to do and sounds great 5 Star Review

    Posted by on 22nd Apr 2015

    this is a great amp if your thinking about buying it stop thinking and buy it! i have this amp running 4 sa 18"s in a blow through my peak is 28hz so it gets pretty shaky anywhere in my truck. i have tryed a couple other big name brand amps and none can take the abuse my system throws at them. they mean business when they say these amps are vibration resistant. and it plays alot better than some amps i have owned it will get dumb low and brings out the higher tones as well
