Stereo Help

[dezquest]

Hello to all. I just joined about an hour ago, and I am need of help with my car stereo. I have an 87 240 DL w/ a Sony Head Unit (GT-200). It doesn't do it all of the time, but after I have had the A/C on I get a humming noise in my rear speaker, even after I turn it off I have checked all of the wiring, and it looks OK from what I can gather. Any advise?

The humming noise ...... does it get louder when you rev the motor? :cool: You might want to recheck your ground wire.

No it stays the same regardless...

This is really the only thing that is annoying. I got the car two weeks ago for only $100. So far I have redone the Inside ( i'll post pictures soon). I changed the Tan(which looks more like puke yellow after 19yrs) to Black and silver. Not quite done yet, but it is turning out pretty good so far.

I also replaced the 4" speaker and added 6 1/2's" to the front doors, and 6x9's to the back. On the front door should I wire the speakers in series? I have them in parallel now and if i turn the volume up past 22, when ever the bass hits the radio shuts off. Any suggestion with that?

I'm no expert, but could it be a fuse? Mine blew a few times randomly when i had a sony head unit, swothced to pioneer and its MUCH better IMO

Ive found that sony headunits are usually noisy, but it could be the blower motor causing interference.

Cool Thanks a bunch. I'm a new Volvo restoration enthusiast, so I'll look into it.
