Aftermarket Stereo Problems

Hi everyone - I'm new to the forms and am hoping someone can help me with this problem. I replaced the stock head unit about 3-4 years ago - no problem. By far one of the easiest installs I've ever done.

Within the last 4 months, the radio has been nothign but problems. When driving (or not driving), the audio will break in and out, much like losing antenna signal when going through a tunnel, however, it's not losing antenna signal becasue it does it when playing CDs as well.

When you go over bumps sometimes the radio signal will go in and out (not the power, just the audio). But it doesn't have to be triggered by a bump.

Seems the only solution is brute force on the dash above the stereo - leading me to believe there was a bad connection or faulty ground. I then took the stereo completely out and re-installed it, taping all connections securely with electrical tape. While the audio cutting in and out has improved (somewhat), it still happens.

Does anyone have suggestions? My next step will be to get all new wiring and try a new head unit. Maybe it's an internal issue with the stereo itself?

Very well could be an internal issue in the radio...also, when you say "taping the connections" are the connections currently made? Did you just wrap the ends of the wire together and tape em up? Try using wire nuts or butt connectors...or better yet, pick up a cheap solder iron kit (under $10 from Radioshack) and solder all your connections (buy a pack of shrink tubing and slip a piece on before you make the connection, then use a heat gun or your solder iron to shrink it and seal the connection).

By soldering it, that will help ensure all the connections you've made are good and tight...then start checking the grounds...could even be a speaker ground shorting out or something.

I should clairfy that by taping I taped the plastic connectors on the wire harness to the leads in the vehicle. I didn't tape any wire end, just the plastic conectors together which terminate the wires. There is no need for any wire nuts, as the wire harness from radio and internally in jeep have plastic plug connectors.

Does anyone know of where you can purcahse the repalcement audio wiring internally for a TJ? I didn't see it on Quadratec.

I installed an aftermarket stereo about 4 years ago. It worked great - no problems, easy install. Recently, the stereo has been dropping audio (both radio and CD). Sometime sit happens randomly, other times it's casued by a bump. It is not just a single speaker cutting out, but all of them (both dash and both soundbar speakers).

I took apart everything and unhooked the stereo and remade all the connections, checking that they were all secure. Still losing audio. So I went and bought another stereo. Installed it. No change.

I'm leaning toward the issue being casued by the Jeep's internal audio wiring or grounds. Has anyone experienced this problem? I'm at a loss for how to proceed now since the new head unit also experiences the same issues. Has to be somethign internal to the Jeep.

Any help would be great as I can't stand listening to music and having it go in and out all day long...
