It sounds like you either blew a fuse, or you cooked your amp. The fuse on the P200.2 amp is a 30A fuse, and it sits right next to the power, ground, and remote wire connections on the end. Pull the fuse out and see if it's blown. You should also check any other fuses that you have in the car before the amp.
Hi, i have a rockford fosgate p200-2 amp. the subs were going fine and then they stopped. There is no power light on on the amp. I think that a fuse blew. I cant find the fuse tho. Where would the fuse be? and is this what you think happened?
