[QUOTE="mc71, post: 8456334, member: 664923"] Thanks, I think it's only the one sub & I do think the sub is the problem.. [i set amp gains with a dmm. I doubt it's +/- phase (wired parallel...final ohm checked with dmm). I spent a month building/sealing the box (3 chambers, 1" MDF, triple baffled, several coats fiberglass inside/outside, seams siliconed)]. Maybe I'm grasping at straws hoping the sub's +/- connections are getting bumped from the SPL (vs facing reality the sub is bottoming out) :-/. It's just weird my first sub having this problem is a GTI mkii (& not any alpine, JL, Memphis, Audiobahn, etc I've had in my past). Although the mkii's voice coil terminals do get bumped more, fitting through box cuttout hole, they seem to stick out more. Guess my real question is, has anyone had a "bottoming out sound" that turned out to be a loose connection? I'll pull the one sub and see what happens....also double check my gains...I'll just recheck everything lol. thanks again. [/QUOTE]
