Amp ground?

Iam thinking thats it, i have my amps grounded in the back seat bolts, but the bolts come from the chasis and through the seat frame and my crimps are touching the seat frame and the bolt from the frame not the frame itself, get it? Either that or its my HU? Im so pissed! Even my subs whining.

Then by process of elimination somethings around with your amp ( assuming the speakers making the noise are hooked the the amp).

What do you mean, exactly?

Yes the speakers are hooked to the amp... my sub whines my mods whine and so do my tweets.

when you disconnect the RCA's and they still whine, it eliminates the HU, since the hu cant cause the noise if it isnt connected.

I'd say try finding a different ground. I would think the seatbelt bolt would work, but try a new location to eliminate that problem.

The seatbelt bolt is too far i think, i think ill end up drilling. But before drilling iam going to try that bolt if i can reach it.

Too far??? How the hell do you figure? Get a bigger peice of wire, it's better than putting tons of holes in your "truck"...

Well i would think its more than 3ft. I though grounds were recommended to be shorter than 3ft?
