Hey all, Ive done some searching couldnt really find what i was looking for so I figured Id ask.

I have a 94 4 door with the premium sound, I recently installed a new Pioneer DEH-1900MP HU without bypassing the factory amp (ill get around to it). I used an adapter harness that I spliced together with the Pioneer's harness so it just plugs into the factory plugs, everything is in where it should be. However, im getting a very faint ticking buzz when the engine is running that is coming from the front drivers side speaker only, the ticking gets faster as RPM's increase, but is uneffected by the radios volume. Also when the HU is powered off, the same speaker pops, this is also un affected by volume. Ive checked all the connections and everthings goods, im not really sure whats going on here. Any suggestions are welcome. Thanks
