My front right channel is screwing up, but at random intervals. My left components, rear 6x9s, and sub are working perfectly, but the right front components have problems occasionally. They either cut out or have this fuzzy sound with a lot of noise while the other speakers are still fine. It happens when the car is very cold mostly. It also happens sometimes when I go over bumps or when I first shift my car into drive and move forward or hit the gas firmly from a stop. Sometimes it's just on and off for no apparent reason. It seems that this would be a wiring issue but I'm not sure. The warranty on my amp runs out on the 9th, so I have to deal with this shortly if it is the amp. I don't see how it could be the speakers, and I would think if it was the head unit both right channels would be having the issue.

My setup is an Alpine IVA-W205 hu, Alpine Type-X components, Type-R 6x9s, Type R 12" sub, and the amps are JL Audio 300/4 and 500/1v2. I won't have a chance to go to the shop where I bought the 300/4 for a little while so any input on whether it's that or just the wiring would be much appreciated.

 

Start with checking the connections at the speakers, and work your way back.

Diagnosing intermittent electrical problems is bad enough in person, but nearly impossible over the internet.
Only real solution is to take it somewhere experienced in car audio and hope for the best.
