I was doing about 120 and went over some railroad tracks and I think I rattled something loose. Now my passenger, front speaker is cutting in and out and crackling at times. I pulled the speaker out and tested it, works fine on a different system. From what I could tell all the wires in the door seemed fine. I also pulled the radio out of the dash, once again all looks fine. Then I was sitting in my car the other day just listening to the radio, the passenger speaker was not working at the time. I bumped the steering wheel and the speaker came back on. I knocked the steering wheel again and then it cut out. I repeated this a couple more times, each time I hit the wheel near the volume control button it would cut in or out. Haven't had the chance to pull the button off and check it out but wondered if anybody had an idea what exactly the problem could be. On a side note, in the future I'm planning on swapping out the steering wheel with a more basic racing style wheel, if there is a problem with the buttons would it be wise to ignore it since they'll be eliminated soon anyway?

 

Ok, I did a little more poking around and think I've isolated the problem. I pulled the radio out while I had it on and started playing around with some of the wires. There was a small black rectangular box that had a red and black RCA type plugs going into it. When I played around with the red plug the speaker came back on and stayed on. I noticed that if I pushed the plug all the way on the speaker would cut out so I backed it off just a bit and it seemed to do the trick. Obviously this is just a temporary fix, do I need to replace the module it's plugged into?

 

That module is not factory - there is no factory wiring with RCA plugs. It could be an auxiliary input adapter like a GM9-AUX or it might be a line out converter for adding an aftermarket amp to the factory system.

 

Yeah, it's an auxillary input adapter. It said on the unit itself I just couldn't remember exactly what it said, and was too lazy at the moment to pull the radio back out. Assuming that's the problem are they generally very expensive?

 

The first question is "are you using it?" Do you have a satellite radio, iPod, MP3 player, or some other device plugged into the auxiliary adapter? If not, just remove it and forget about it.

If you still need it then you can get a GM9-AUX for $65-$70 online - perhaps cheaper on eBay.

 

I was talking to someone else about this and they told me to do the same thing that you did. However, when I pull both of the wires out it kills all of my speakers. I was told that the amp should only be powering the subwoofer but it appears it's affecting all of the speakers within the car.

 

In that case it must be a line out converter that is connected to an aftermarket (multi-channel) amp. The previous owner must have replaced the Monsoon system and rewired all the speakers. You can pick up a replacement LOC at any audio shop (even WalMart) for $15 or less.
