Hello,


I am new to this board and a first time poster with a question.

I have installed a new radio and speakers using the factory wiring.
I got one of the adapter harness' and soldiered the new radio wires to the harness and plugged it all in. I am getting a constant hissing noise that I cant seem to get rid of. I was wondering if there was a factory amp that needs to be disconnected or wired around if possible? I wanted to try to keep from having to run new speaker wires to the doors and rear deck if I can.

I have looked under the front seats and everywhere else I could think of for the amp if there is one. Not sure if there is or not.

Any advive or sugegstions would be greatly appreciated
