Engine Noise :(

I had a hu replaced with no ground loop problems. Then I installed an amp and replaced all the speakers as well. Now I have a ground loop, which is annoying. Does this same technique work for my situation, since I grounded the amp to the frame in the middle of the car? Just checking, or if I have to do something totally different to get rid of my new ground loop. Thanks in advance.

How and where did you run your rcas and power wires? Did you sand the ground spot down to bare metal before putting the ground wire on? Were did you ground your head unit too? Also what kind of amp is it?

the hu was installed using the factory harness connector. so i believe it was connected to the ground through that connector. I would have to double check that to be sure. I ran the power along the passenger side and speaker wires with rca along the driver side and the remote lead as well. Figured those would be ok due to low power, compared to the power wire. Jl 900 5 amp is grounded in the trunk to a bolt that I didn't sand because it was pretty large in size(thought it would suffice). I am just wondering if the hu wasn't grounded accept for the factory connector it is connected to. (I never installed the deck, just
added the rest)
