Hey guys, first time post for me here.
I have had a system in my vehicle for awhile, I was using a Kenwood KAC-7252 (old i know, I have had it for about 12 years i think?) and i WAS running two MTX 12's on it and everything was running and sounding good. I have 4 gauge wire for the power and ground. I just got a pair of kicker comp 15s off of a friend. When I try to run them ill get a half-assed sound and all the lights will dim, including the amp light, then nothing happens for a couple of seconds, and then it will do the same thing again. What could be going on here?
