OK, so i recently got a rockford mono amp P300-1 as well as a P2D412 12" sub but recently my dumbass friend decided has was going to open my driver side door and my alarm went off. of course, my sub and amp aren't working now. anybody know what could possibly be the cause. i dont know shit about cars, but i can drive the hell outta dem. any info please, thanx in advance

Aight, nevermind. I bought it back to the place that installed it and they fixed it in 10 minutes. He did tell me i won't have to worry about coming back to fix the problem again. Thanx N E Way
