I have a '07 Type S w/Nav and lately my door speakers have been shutting off. Actually, it only has happen 3x, and it doesn't last that long. But, today it has lasted all day. Even disconnecting the battery didn't fix it. It's kind of weird, I almost feel the amp is buggin' out. It's similiar to when I have my cell connected via Bluetooth and I get a call and the amp lowers the volume and kills power to the front speakers.

Has anyone encountered this? I was searching, looking for amplifier hiccups. I don't want to got to the dealer unless I was sure because I do have some mods.

FYI...I have only replaced speakers and added an amp for the sub. Noise Cancellation is disconnected. This set-up was done 1 year ago with no issues, until now.
