Fully tune-able true 5 channel amp. Top of the line quality all around.
so far I can't find one issue with this amp

Sonic Electronix even has the best price but.........

1 HUGE PROBLEM....
Under the description it says it requires 1/0 Gauge power and ground wire.
This is absolutely incorrect. It can only fit a maximum of 4 gauge power and ground wire. So when I ordered this amp I purchased a 0 gauge install kit to go along with it. Thanks to Sonic Electronix's advice I wasted $100 and set my build back by two weeks. Hopefully they will change this information immediately so no one else makes the same mistake.

I have this amp on my car and the settings and quality of this amp are top of the line. It makes it super easy to have just 1 amp instead of 2 separate amps. Lots of power, great sound quality and good built quality.
