so ive had my amp for a while now and ive been getting this weird problem with it, so what happens is when the amp turns on the green light on the amp dims and will slowley go out then turn off but the weird part is that its getting 14.4v then when the amp turns on it drops to 8 volts, and whats weird is that sometimes the amp does work and it gets the 14.4v but then all of a sudden it gets 8 volts the ground is prefectley fine. has this happened to anyone else its an audioque 2200
