Don't know if its possibly related to this: http://www.chevelles.com/forum/Forum22/HTML/001822.html or not.

Anyway,
While my key is in the on position, the stereo plays out nice and clean, as soon as I turn on the car, from the speakers you can hear an annoying buzz type sound. I have a pioneer headunit, with 6x9's a 12" sub and a 800 watt amp in the trunk. The headunit and the amp both have fused powerleads running to the positive side on the battery. All grounds are clean, and no fuses are blown. The stereo worked fine for months, then I had my above mentioned problem with my domelight staying on, day after I took the bulb out of the domelight I swapped motors.(When I swapped motors I went through and cleaned and tightened all grounds) The stereo still was working fine with the new motor, and then in the last week or so it started its buzz. What leaves me boggled is it only does it while the car is running? When its just in the acc position everything is fine.
Any Thoughts?
Thanks In Advance!
edit-forgot...I just checked and tightened all the wires at the amp and rerouted the power wires in the motor compartment to a cooler spot and its still doing it.

Try filtering the 12 volt input to the stereo. You should be able to get a filter choke (coil) fron Radio Shack for a couple of bucks. Fairly common to get a whine noise from the ignition. Later on the dome lights.

you might try to get the noise suppressor at a stereo shop instead of radio shack. I got one a while back that did not work very well (poor quality).

This was a couple years ago, though. Their quality could be better now.

If it has an HEI ignition try replacing the capacitor/condenser in the distributer.

It does have an HEI in it. Come to think of it, when the new motor went in I found that my Summit HEI was junk(the inner guts(whatever they're called) under the rotor wouldnt return and would stick like crazy) So I put another stock HEI from a friend in there(used) with the new cap and rotor off my old distributer. Come to think of it, I eyeballed the timing on the new motor(it runs good) could too much or too little advance be causing my stereo problem? Its not pinging or popping and responds nicely.
thanks for the advice so far. I'll add the filter in, but Im kinda thinking, is the filter kind of a bandaid fix since the stereo all worked fine for several months prior to the buzz?

Nope,i wouldn't think so.Try the condenser change,there cheap.

 

[supersport396_2000]

Did that fix it??

 

[RussD]

Haven't gotten to it yet. Its been fluctuating, dont hear it one time sorta there sometimes. I havent been driving the car either other than a little bit this morning. I need to get to it though, gotta have the car dialed in for next saturday. Girlfriend is taking me to her senior prom and doesn't want to take a limo, wants me to drive the 65.
