    damaged head unit?

    I finally connected my front componets to my amp today to find out that now i have a weird disturbance in my rear right speaker. even with no current going thru that speaker there is the interference. (i moved audio 100% front 100% left and the noise was still there). I havent been able to check the grounding yet, as well as make sure im getting a good solid ground, but the only thing that strikes me as strange is....when i switch from FM to CD player, i can hear the cd spin up(through the speakers), then 2 beeps, followed by another cd spin up, followed by music. Is this strange to anyone besides me? sounds like to me that the cd player itself is introducing the noise. any suggestions?

    hmm, you have a compact CD player you could try to feed sound thru the amp with? im no audio whiz but, it sounds to me like it could possibly be grounding or the amp its self if not the CD player.

    I'd check your polarity on the speaker (swap your + and -). I accidentally did that on one of my subs and it sounded like crap because they were "fighting" each other. If that don't work, try swapping your left and right wires. If the sound stays in the same speaker then I would say something wrong with the speaker. If the noise goes to the other side then it's definitely something with the wires, amp, or something further.

    I also like the idea about hooking up a portable CD player. Nice idea. 3.5mm to RCA cable will be needed.

    If you have everything faded away from that speaker then something strange is truely amiss.
    I've been involved in car audio for quite some time and have never heard of this happening before, what are the chances you accidentally stripped the speaker wire and it is making contact with the chasis of the car causing some sort of feedback issue?

    Well, i dont know what the problem was, i rewired my amps today, but the only thing i did was put electrical tape around the RCA cable contacts, because it was possible that it was touching the body of the car. Also i put my wires out of mind(out of sight). Anyways i can still hear the cd spin up and the 2 beeps, but the buzzing/humming noise is gone..or maby my Xover is canceling it out. Oh well, we shal see. thanks for the help though.
