Anyone have this done to their cars? I want instead of having just a plain wooden rectangular box made for my 3 JL's I want to want them to make my trunk Fiber Glass so it can be more like a round shape to it because I would really like mine custom. Anyone want to share some good advice?

fiberglass would be fine for free air speakers but for subs..... enclosed box made with by spec will give your subs optimum performance

WHat do you mean fine for free air? DO you think that fiberglass boxes cannot be sealed or made for a certain internal volume. Fiberglass boxes are GREAT for ALL applications! But as stated, they should always be built to the manufacturers specs. for internal volume! I have made several, and they were ALL sealed and ALL were built to manufacturers specs.! Everyone sounded great! Not to mention that fiberglass can be made much more rigid than just about any wood!

i would have thought that fiberglass would crack from all the vibration..... if you were talking about fiberglass housing for kick panels and doors.... than fiberglass should be cool.... but for subs.... I would go with a box

Thanks for the info guys but unfortunately i will not be going for fiberglass cuz over here dealers told me it's too expensive and i will take their word. How much do you have them wes?

NO, fiberglass is GREAT for sub-enclosures! It can be made much more rigid than MDF. If built correctly (thick enough), you can get the same, or better, results with fiberglass that you can with wood. Actually there are TONS of SQ competitors that use fiberglass sub enclosures! And yes, custom fiberglass enclosures can be very costly! If you are on a budget, either do it yourself with fiberglass, or go with an MDF enclosure!

MDF stand for medium density fiber board, it's one of the most common materials used to build enclosures. You would typically use MDF in place of say, particle board, or other types of wood. It's in-expensive and is easy to cut! It's also dense, which makes it great for speaker enclosures! You can pick it up at the local Home Depot or the like. Or you can make one out of fiberglass, typically glass boxes start out with an MDF frame and then fiberglass is laid in the desired area to get make use of the contours in the spare tire well, or whatever area you wish to use. I would suggest reading the information on my site, even though it is regarding kick panel construction, it is a very good starting point for learning to build things with fiberglass! Once you have checked that out, I'd be happy to answer questions for you! Also you will need to be able to determine internal volume if you want to make a box that is worth a ****. SO here's the formula for that.

Height x Width x Depth = Internal volume in cubic inches.

To translate cubic inches to cubic feet.

IV in cubic inches / 1728

This should get you on your way! And remember that this is internal volume, so you'll have to accomodate for woofer displacement and materials!
