Check out the GDL site that can-do mentioned. It will tell you everything you need to know. The two phillips screws holding the amp in can be ABSOLUTELY impossible to get loose, besides you can't even get to the one closest to the fire wall. Fear not! GDL has a tip on getting it out. I have five used ones from the werecking yards in the last week and a half, three do nothing at all, one will accelerate only, and one works some of the time and today it started competing for attention over the radio. I think that going to GDL is probably the way to go, not only that...I believe that they have a special going right now that offers a free lifetime warranty if you ask for it. Cant beat that.
