2009 Yukon Denali JL Audio, Bose Premium - Issues

[fredfred]

I hope someone can help me.

I have a 2009 Yulon Denali with the Bose premium system that includes XM, navigation and a back-up camera. I purchased a JL audio amp and subwoofer enclosure. I took the equipment to a local installer that stated they could do the install.

I inquired with JL Audio prior to the install just to check where to get the feed for the new amp because the person that was to do the installation didn't give me that warm and fuzzy feeling.

Anyway, JL Audio emailed me back and told me to get the amp feed from the factory subwoofer wires. No line converter required. Sounds simple enough.

The installer didnt take the advise. They used a line converter anyway. The system sounded so good when I got it back. About a week after the installation, there is a problem. For no reason at all, the bass goes up full blast and drowns everything else out. It doesn't happen all the time but is getting progressivly worse. Finally got so bad I took the fuse out and cut power to the amp.

Does anyone have a reason why this is happening? JL Audio quit replying to my emails. I am thinking about removing all the equipment and sending back to Crutchfield. Any help would be greatly appreciated.

I hope someone has fixed a similar issue.

Thanks,

X2.

To be honest, when I performed my aftermarket upgrade/install in my '08 Silverado I simply decided to completely bypass the Bose crap. Way easier and sounds AWESOME!

LOC is a PAC Audio SNI-35. Amp is a JL Audio Slash V2, 1000/1v2.

Problem fixed. It was a bad sensitivity input rheostat in the amp. Go figure. Anyway, I took out the LOC and checked the wiring. Switched to the hi voltage input of the amp. It was still having issues. I started adjusting the filter settings on the amp. I adjusted the sens. input with a small screwdriver. When I wiggled the rheostat, presto. Subs sounded great. I stuck a toothpic in and wedged the rheostat to one side. Working perfect now. Waiting for new amp from Crutchfield. Very happy issue has been resolved. Thanks for the help.
