Since I've brought my '08 Redline out of winter hibernation, I've had 3-4 occasions where I all of a sudden have much reduced bass coming from the sub behind the passenger seat. I'm wondering (before i start taking things apart) if my issue is the Monsoon amp is overheating ? The only solution I've found for it so far is shutting the car down for 5 mins or so and then everything seems to go back to normal. Any other ideas / thoughts? I'm assuming that to get to the Amp I need to remove the trunk liner?
