hi all, my system has been faultless up until today when i was driving it and the bose symphony II just switched itself off and then on again. happens randomly and with the volume high/low. i thought it maybe a lose wire from the recent andy mac sub i installed (ie ground or remote) but it still happens when the car is at a standstill. i have tried it on my ipod and cd's and it still happens. has anyone come across this and is there a way to fix this? any help would be appreciated! i am running the bose symphony II with standard speakers and the amss. there have been no issues since the install over a month ago.
