Sealing off a hole cut for a sub?

[TQua2009 10+ year member]

Is it possible to seal a hole that was where a sub was originally mounted and cut a new hole in a different position on the box? If so, can anyone give me some tips on how to do this?

oh lawd.

build/buy a new box. this is the best/only way

or use piece of MDF + Titebond 2 or 3 + seal up the inside.

then cut new hole. but why?

I cannot build boxes. Every time I try, I just end up wasting $40 on a sheet of MDF and about 8 hours time.

Well, the reason is that my subs are currently downfire, and the XMax is larger than the space between the box and my floorboard. So, I will be hitting the floor when I get my new amp in. I need to face them towards the seats and I have a complicated back seat, so building a box is hard for me.

im not sure what ur wanting to do. but i dont see why you cant juse put another baffle over your current one and cut a new hole

Because to fit one in, it would have to be smaller than the hole correct? I was trying to figure out how to completely seal it with that in mind. Sorry for being so confusing, long day at work and getting ready to go to my other job...

Maybe do it like a sheet rock patch.

Trace the hole on another piece of wood. Cut it out the screw the circle onto a new baffle then screw the new baffle onto the box. That way it's smooth inside the box.

Ahhh, good idea. I will try that after work tonight.

what is the goal of this?

Any chance of just ghetto rigging some supports under your box to shim it up higher?

The goal is to get them to stop hitting my floorboards every time the hit. And I did try rigging shims, out plywood first, then a nylon block. Plywood broke, nylon deformed from constant pressure. So I was back to where I started. Also, on shims, it slides around bad.

why don't you get metal brackets.. thick ones.. and use a few.. and secure the box so it doesn't slide..
