anyone have fiberglass boc instruction that are not for a spare tire well. Also how to fiber glass boxes sound? Thanks

 

My instructions to you would be to get a pro to build it. If you haven't done it, or watched it being done, it is probably above your skill level. But they sound great, and are much lighter than a wood enclusure. Lots of normally dead space with a wood box can be used as airspace with fiberglass. you can get into every nook and cranny in the trunk with fiberglass, and have more trunk room when you are done.

 

Enjoy. I will be trying this at some point. I figure if I *** up, it is only money. :-D

Don't mix it too hot, buy and wear lots of latex gloves, cover everything that you don't want coated in resin with a plastic drop cloth, and use a fairly thin mat and cloth (lays down easier).

If done right the box will nearly sound as good as an MDF/birch ply enclosure.
