i did the mod where you take out your jumpseat and putin a sub, and when doing the hook up i already had all the wires from a previos sub system that i had, and was able to use all the wires again , i hooked every thing up and it worked great , but now when i got in it today i hear the alt. running in the sub and it also made all 4 speakers make a cracking noise and it sounded bad, just wondering if you al think its a bad ground or a short in the system , or ? any help would be grand.
i have a sony hu and 4 alpine 6x8 door speakers and a jbl sub. as well as a sony amp
