Radio Install Problems
I have a 1992 Saturn T-2251. It had all the wiring in place for a car stereo with speakers already in place, but the radio had bit the dust. Simple enough, right? Just replace the radio. That's what I thought too. I have done several car radios in my life and figured I could handle this one. We got a stereo (Boss 622UA) that fits our budget/needs (mp3/ipod hookup, remote control, etc, etc) and got it mounted in place. The wiring seemed straight forward once I figured out what was what. When I turn it on it has a slight low level humming in the speakers. I have had car stereos do this before and figured it could be fixed with a noise filter. Then I turned on the other breakers in the breaker box. The speakers put out a loud pulsing noise that makes you think the trailer is going to blow up. Turn off all the other breakers, except for the power converter and it is back to the low level humming noise. I am stumped. I was thinking it could be a ground issue, but I have the unit wired to the ground that is coming straight from the breaker box. It should be a solid ground hookup. I tried to consult Boss to make sure it wasn't a problem with the radio, but I can't find any wiring/installation instructions. There is a breakdown of the unit assembly in the owners manual, but that's it. Any thoughts?
