All I did was change the 8 gauge to the 4 gauge wiring, added a big purple ground wire instead of the smaller brown one and used different wire from the head unit to the amp. I moved my amp from under the seat to mounting it on the box in the back as well. Now I notice that the subs arent as deep (12" slp) and they sound worse when they get turned up. I dont know what I did wrong. Did I do something with the wiring behind the head unit? Is it the new bigger cables? And the amp is a 2200 watt soundstorm. Your help is much appreciated.

 

You prolly bumped a setting on the amp...

BTW: GET A NEW AMP!

 

How many sets of rca's does your headunit have? Do you have the set for the sub amp plugged into the sub set? Does your hu have hpf?

what the hell is a hpf?? And why should I get another amp? A friend of mine who installs amps says this is one that he recomends when it comes to price and the quality. I actually like the amp and there may be a better one out there for what I payed for, but I wont know and right now I am pretty happy with it.
