DB Drive 5x7s in the front, DB Drive 5x7s in the back (high power rated gear).

Crystal clear, with room on the gain for more!

Sound quality

These are one of the better amps sonic carries. You can run a 2 way active off just this amp or run a set of comps up front and bridge the other 2 channels to power a small sub. There under rated just like all DC’s stuff to this thing can push every bit of 120watts a channel if not more.

Worth every penny

Replaced my 1500watt planet audio amp for this amp and it is 10 times louder and way more clear I was beyond surprised. Right it is pushing 4 6x9s I will end up putting it on 4 kicker ks components and the 175 watt one on my 6x9’s
