My XXX has been sitting out in my shed for a few months, Waiting to get installed..But from the looks of things I dont think thats gonna happen for quite some time.. I have a system (or somethin like that) in my room compiled of all my dads old junk..a Quasar Eqaualizer..Onkyo TX3000 (100wt. rms) amp. & 2 AR(??!) 8"s..I have no idea what year this stuff came out, But my guess is over 20 years ago..Its all works fine though..I also have a 15" no namebrand sub I got off one of my friends..Im wondering if i could pull that out and throw the XXX in there temporarily..Im not too sure howd id wire it up..but..I just wanna know if this is a good idea or not before i start rippin stuff apart.
