each sub is wired by its self in series with the amp at 2 ohms. and the grounds are in good shape, i made sure that i checked it. but i went to visions today and talked to a guy that i know and he gave me a four gauge wire kit. i think that it is going to help alot actually. i only have 8 in there right now because thats what the kid had in it before i bought it with two acoustic speakers hooked up. when i put my system in i didnt even think to change out the wiring.

Ah, you have your system wired incorrectly.  If each sub is wired for 2-ohms and both are connected to the same amplifier, then you are placing a one-ohm load on the amp.  It can't handle that.  You need to re-wire the system and place both subs in series so the amp gets a 4-ohm load.

The wire gauge of your power system will not cause the problem you see.

Just curious here,  What is the impedance of each voice coil and how many voice coils are on each woofer?
