I am going to cut a piece of plastic and just JB plastic weld it to the back. Should work perfect.I'm not sure to what you're referring to? But if there is any hole, you plug it. you want the enclosure sealed.
I'd probably use a few layers of fiberglass and resin. expensive and messy since you'd only need a few oz of resin and a couple small patches of fabric, and they are not sold that way.
Or you could smooth out the area, use a shape of plastic panel (kydex, delrin, etc), and glue that in place with a strong epoxy gel.
There are two things wrong with this approach.I personally think the stock sub box should be ported. Open it up a bit.
What sub are you replacing it with?
I put duct tape over the inside, then silicon caulk in the hole from the outside.I am upgrading my sub and using the stock box and I was wondering if I should be covering the hole in the back of the sub box that is used to mount the stock sony sub.
If I need to, how do I do it?
If I hadn't already drilled the sub in then I'd do that. I'm just going to put the ABS over it and it should be fine.I put duct tape over the inside, then silicon caulk in the hole from the outside.
Its the typical rockford replacement. I've had it for a while but I decided to put a .75in spacer to lift it a bit and do the polyfil mod. Sounds good on an aftermarket amp.I personally think the stock sub box should be ported. Open it up a bit.
