the power in set screw on my JL A6450 6 channel amp got cross threaded by a previouse owner, while playing wiht it, i managed to get it stuck the allen socket isnt to torn up, its a pretty hard steel, but i can't get the damn thing out its torn up just enough to let my allen wrench slip. the whole power block insert proboblys needs to be replaced. anybody local to the north east coast who can help me out, or maybe even just walk me through where to get the parts and the procedure, it's not a hard solder job really, but I'd rather have somebody do it who knows what their doing. kind of puts me in a bind, i sold my current amp and intended to use this JL amp temperaley while I worked on getting the new one in. i'll be able to throw something together with some other amps to get my car stereo running, but the problem still remains with this JL amp.
