Been trying to get my aftermarket stereo to work. It was on the vehicle when I bought it (1990 cherokee) and it never really worked much. The issue is it cuts in and out when I'm driving around. I can get it to work pretty well just sitting in one spot (I thought it was just a bad antenna connection) but when I move it starts getting choppy. I've heard it could be a bad ground but how can I test that? Thanks

 

it could also be a grounded out speaker wire. easiest way for me to test was take the stereo out and hook it up on the workbench. one speaker, and 12 jump box. i moved the speaker from wire to wire to check all the channels of the radio.

after i determined that the radio was fine, i put it back in the jeep.. but .. i only hooked up on one speaker at a time.. until .. the driver rear roof speaker negative wire caused it all to stop working.

 

Well, I know for a fact that the passenger door speaker doesn't work. Driver door speaker had a bad connection but I fixed that. How'd you connect it to one speaker at a time?

 

manually wiring it with jumper clips and finish nails. you clip the clip to the nail.. and the nail slides into the harness fine to make the connection.

 

Here's something else worth mentioning. If I'm sitting in the driver seat listening to the radio, even when I'm not driving, if I lean back in my seat the radio cuts out. Not sure if that helps any.

 

I'd bet that the speaker wire runs right under your seat, and thats likely where you'll find the short.
