Default Do you subwoofer mounting screws come loose?

Two times now since I put my subs in my car I hear a horrible noise, quickly turn it down thinking "shit I blew my new subs," pull over, and one is leaking air around the gasket somewhere. They've been in for less than a month.

I've never had this problem before and want it to stop! What's the deal?

what type of wood is your baffle made of and what type of screws are you using?

You're probably over tightening them

3/4 mdf (single layer), 1" drywall screws. Not the self tapper kind for metal studs.

When I first did the holes, I went about 3/4 of the way in with a drill on each, then hand tightened after that. I guess they could be overtightened, not exactly sure how to know for sure.

dont predrill the holes and use a #10 screw no issues

drywall screws suck and if you reuse them then they will probly snap

plywood and thicker screws. I use sheetmetal hex head 8mm screws. Get so tight into double baffled birch that my corded drill wont go any tighter with zero stripping.

Hmm hadn't thought of just using a thicker screw lol. Have to take em out the weekend, rotate a bit, and replace with thicker screws. Thanks guys. Will report back if they do it again.

Edit: what's the plywood suggestion about?

plywood has actual sheets of wood anchored together so your screwing into solid wood. Whereas MDF your basically screwing into glued together wood pulp. Make sense?

take the screws out, shove a couple toothpicks in there and put the screw back in.
