Hey guys. Just put a kenwood excelon in my girls car. This is more a car specific question than a tech question. I personally own a grand am, and do installs once to three times a month around town here, but this is the first Grand Prix I've done. I notice when opening the drivers side door the speaker cuts off, but if I push the door latch to simulate the door shutting it turns back on. Normal? She also stated for two or so days starting the car some of her speakers wouldn't turn on for a bit. I bought the metra gmos-01 or whatever it is. Any ideas?
