Stereo & Electronics - Rear speaker box completed. My 1st fiberglass project.

Well, I never made a speaker box out of fiberglass before, so this was an experiment. Took a good 40 hours of labor in the end, between measuring, sanding, laying fiberglass, and painting.

One thing I noticed is that it is not as efficient as the wooden box I had previously. I can jump up and down on this fiberglass one (it's strong), but it still resonates a little and it does not produce as low of bass as the 3/4" MDF box did. Guess nothing beats MDF for low-end thump. :bang: Oh well, I spent far too much time on this to not run with it!

The up side is it looks a lot better than the wooden box did and it's still loud. :) Let me know what you think. I'm happy with it. :)

That looks real clean! I like it a lot!

wow that looks great!

Looks good, very good fiberglass work, but the white looks out of place in a gray interior.

Thanks for the compliments. :) I picked white because the exterior is white. So's the Hurst shift knob. Ties the outside color into the inside. At least that was the idea.

great work, but shittty sub..... you should start making boxes for people who need a 12" box

unless u couldnt with that spot. you should have made a box out of mdf and fiberglassed over it and around it

Looks like the grill is just about on top of the surround.

just curious, how did u get the face to look that way, is it competely fiberglass?....... because I just used a 1" MDF as the faceplate portion and the rest was fibergalss. You should make a write up on how u did it for the do it yourselfers, great work honestly

looks good

If I do another, that's exactly what I'll do. I think the bass would be tighter. I origonally went with pure fiberglass thinking I could get a bigger volume (the current box extends through part of the rear panel.) and thus a deeper bass. In retrospect, nice dense 3/4" MDF is a better choice, even though the volume is about 1/2.

To answer other questions, the front is 100% fiberglass laid over stretched felt and smoothed with bondo. The sub is $hit....but works suprisingly well with the inclosure :jest: Also, the speaker grill comes darn close to touching the surround. Doesn't vibrate though.

Thanks again for the compliments :)

very professional looking. Good job.

I'm sooo jealous......

Where some good places to get the materials like resin and fiberglass chop mat from? I went to lows and no one was very helpful.

Very nice box by the way!

currently gathering stuff to build my own box just like that for a 12" W6v2.

how about a nice write-up for some fellow f-body peeps (myself included of course)?
do you know how much volume you got out of that with the extention?

Very nice!! Good job!! I made one out of plywood. A million seams and not anywhere near as nice looking as yours.

Thanks again for the compliments. :) I got Bondo fiberglass resin and fiberglass mat from Wal-Marlt of all places. Ditto for the felt material and the Bondo filler material. I will have to work on a write-up. I pretty much did it like the sticky that's at the top of the stereo section here on "how to fiberglass". I will measure and post the dimensions for the front template. Just give me a day or so.....

You might try coating the inside of the box with some spray in dynamat for better wave suppression.

For a first time you did an oustanding job :cheers:
Although I personally would have matched the box to the interior.
