Stereo Troubles

[79_Conti_Mk_V]

I recently got a brand new cd headunit for my pickup, i installed it in there for about 2 weeks and it worked flawlessly... I removed it from the truck and installed it into my lincoln...now i get no sound what so ever... i ran my own wires, not using any of the factory harness, so i know the connections are good.

But oddly enough, i get alternator whine through the speakers when the music will not play through them.

i've been told i might have blown the channels in the radio, but i don't see how this could be possible with it still putting out alternator whine through the speakers..

Any of you audio gurus gimme a shot here, i need to know if it needs to be returned or not.

hm,... Got a meter? Actually, is it possible you hooked up 2 speakers and the fader is set for the opposite 2? I'd just check the balance and fader before I did anything else. If you have a meter you can check for voltage on the speaker wires at the back of the radio. Make sure you're set for a/c voltage at 10x scale and crank the volume up. The voltage will rise with the volume. If you read voltage, the HU is good. If there's no voltage, check the HU to see if there's any switches on it that would change between RCA's and speaker leads.

I never tweaked the settings of the stereo, just installed the speakers, wires etc. and installed the HU. I had it playing at one point, but i had to fiddle with the speaker wires to get it work...hrm.

No meter, so no way for me to check the voltage...ugh. Any other means of checking out the HU before i box it and punt it? :D

Had to fiddle with the wires? could the plug pins not be engaged? If you have some other speaker that's known to be good, could be a home bookshelf or something, tap it right off the back of the deck and mess with the wires with the HU in your lap.

Check the fuses. There should be one in the back of the head unit.

Did you connect the remote line? If you have a factory amp, you definately need that.

You may want to reconnect the stock head unit and make sure it still works.

The OEM head unit for my car got lost when one of the previous owners decided that he was going to just install a nice new cd head unit in the car, so there is no way for me to check it out.

I'm thinking about just putting an 80's ford cassette player in it, and putting a cd changer in the trunk... it'll solve a lot of the headache that i'm having right now.

Interfacing an aftermarket CD changer to an 80's factory deck? Seems to me that would be a bigger challenge than what you're facing now.

I was under the assumption that you were not using any amps outboard of the headunit from your comments on new wiring. Is this the case or no? If you are than that opens up possibilities for more problem areas.

[79_Conti_Mk_V]

No amps, just the wires from the headunit directly to the speakers. The plug pins can't be loose in the back of the stereo, as everything is hard wired directly into the back of the unit, so no problems there.

The type of head cd changer i was looking at connects to the stereo antenna, and will play through the stereo that way, i don't see anything too hard to setup about that.

But then again, i've never set one up so i don't know really what i'm looking at either.
