I've got a 97 that came with the Delta radio, but the previous owner had installed a clarion HU and replaced the rear speakers with some aftermarket units. There's also an amp and sub installed, but wired nice and separately. I'm getting a fair amount of distortion and interference from the rears, and I was wondering if it would be better to remove the nokia amp, especially since the amp is just hanging by its wires below the speaker. They're wired through the stock wires, so if I took the amp out, which wires would I have to run to the speakers? Or would it be better to run some 18 gauge wire from the HU's outputs?
