recently purchased a Road Gear 250w rms mosfet amp. hooked it up to a RF HE2 and it sounded awesome! pounded my head off in my little integra. only problem i have now is that when i was driving, i went over a hard bump in the road, and it killed the amp. i checked the fuses and wiring and everything is ok, but every time i turn on my radio, the "protect" light on my amp illuminates and nothing works. what can i do?
