first of all i have a 1996 cadillac deville that i just upgraded the big three and put an aftermarket alternator got all my rcas and 2 runs of 0 awg and speaker wire ran. keep in mind that there are no amps hooked up just all the wires ran to the trunk. i have pulled EVERY fuse out the car and i still get like 2 volts with a muti meter from my negative on the battery to the ground wire. what could possibly be the problem.
