i have a hifonics brutus 2000 watt amp about 3 years old... i have it in a 4 door dodge ram powering 2 m.a. 12's, its been working great until lately... it will be playing and then it will cut out randomly... i checked all connections and everything seems fine... i got pissed last week and hit the top of the amp and it turned back on... now whenever it turns off, a slight hit and it turns back on...

idk if the amp is on its way out or it just needs something inside re-soldered... any help would be greatly appreciated

thanks
