Alright guys buddy of mine has a fosgate power hx2 10 that he bought from my best friend brother in law that was givin to him....yea i know ****ed up ain't??? well he doesn't have enough power to even push this monster he is pissin it off with 500 watts from a sony 4 channel amp.... so sad.......well i made him an offer i would give him a brand new alpine 12 type s for the 10 and i would build a box for him. well the box is done and sounds good in my car and he likes it, hooked it up in his car, plays for awhile and his amps get hot and shut off. the 10 never done it but the 12 does it, turns the key off try it again plays for a minute and it gets hot and off it goes. So my question is what is causeing this, it never done this in my car on my amp which is a brutus 2000 any help would be thankful guys holla atch boy and help me out.
