Stopped by the Autozone to have them check what is causing the CEL light to come on my girlfriends 2001 Jetta. After the guy told me what the computer says is causing the CEL, he said he would reset the light in order to turn it off. I thought, cool. Well, afterwards when we drove away, I noticed her aftermarket stereo system was not working properly. Had to turn the volume all the way up, and it just sounded very very muffled. Has been working perfectly up to that point, in fact, was listening to it as we drove into the Autozone parking lot.
Obviously, resetting the code light did something, but I have no clue. I checked the fuses for the stereo, disconnected the battery terminals for a few minutes, but nothing. It's an Alpine 9826 head unit with a JL audio amp.
Could this be something with the security system?
Thanks for any help!!

Thanks man!
It was professionally installed by a very reputable company, in fact, I am good friends with the manager, so I assume everything was done correctly. Just seems way too coincedental that everything was working perfectly until the guy reset the code. I guess I will have to take it back into the audio installer and have them give it a look. Very very odd.
Oh, and thanks for your DIY on the brake light switch!! You da man!

Excuse my ignorance guys, but what is the K-wire?

Thanks man, I will do the little diagnostic check with my voltmeter and a resistor. I am starting to think that this is the problem.
