Thread: Need help with sound system for grand prix gxp

For the box covering contact your nearby car audio shop. I guarantee you can get some from them, otherwise you can order charcoal carpet from crutchfield or pick up the cheap stuff from walmart though it doesn't match.

Puting it onto the box is as simple as buying multipurpose spray adhesive in a can, theres alot of different brandss and i dunno whats best. I've been using the 3M stuff and its never given me issues even when i used leather. Just make sure you give it a few seconds to tack up on both sides before you put it together.

As for the fiberglass most hardware stores sell fiberglass matt and resin you just have to ask where its at. If the one near you doesn't, yet again head to your local audio shop. Otherwise you can order it online like everything else.

For finishing off the pillars you can use regular body filler to smooth it out a bit. Then you can use the textured interior paint that o'reily auto parts sell. Just make sure to take your time with that paint.
