[QUOTE="PSturmer, post: 8119093, member: 568966"] i suspect the amp ground is bad. to test this theory measure the voltage between the negative terminal at the amplifier and your negative battery terminal under your hood. if this value is not 0 or very close to it, then i would recommend running a full ground. whenever i run two or more batteries i always just run a full ground and the rear batteries need not even be grounded to the chassis. in other words all batteries are wired + to +, and in the same exact manner they are wired - to -.
