Sub enclosure complete

[SK]

Completed the sub enclosure last week. It replaced the one I built a few years ago....This one is much more compact - made out of fiberglass and molded to the curves of the floor and back seat. Sounds great.

Very clean, I want to do something similar on my car........would you mind emailing me the dimensions and/or plans if you made any?

later,

Nice Job SK.

Also, if anyone is looking for audio/install ideas, you should check out the job on this 1983 911 cab:

A bit over the top IMO, but the work (and gear) is top-notch.

I would consider myself a fellow audiophile, but I could never bring myself to ad that much weight to the car!

I also use JL audio subs in my 79SC. I made a similar setup under each front seat for my 8" subs. There is 4 inches of height x 13 inches wide x 13 inches long. Use the fiberglass to get the contour of the floor and use wood to form the sides ( 3.5inches tall). Finally use .625 thickness for the top. You end up with about .3 cubic feet for the enclosure. It is a good complement to the other speakers in the car. Also the most important part is you cannot see anything!! My amp is at the front of the pasenger footwell. Mounted to the wood floorboard but facing towards the front of the car. (Alpine 5 channel)

I did the car audio stuff when I was younger. I still love the music but now I have a car I love much more.

In response to the plans request:
Here is how I did it.
The box is made of medium density particle board and fiberglass.
The face plate, inboard side, half the back, and the top are made of particle board. The bottom, outboard side, and outboard back is fiberglass.

I started by making a frame.
1.I cut out face plate 18.5” x 10” medium density particle board 5/8”. Custom trimmed right lower corner to fit curves of my floor (see drawing). Also cut out the hole for the speaker.

2.Cut side panel (this would be the inboard side of the box).

3.Cut the back panel. Only half of the back panel is particle board. Since the foot well wall curves, the back panel is half particle board, and half fiberglass. You will be able to see where the wall is flat….this is where the wood will go.

4.I screwed the face plate, side panel and back panel together and custom fit it into the space.

5.Once I was happy w/ the overall fit, I removed the frame and covered the interior of my car w/ a plastic painters drop cloth.

6.On top of the plastic, I laid a sheet of fiberglass cloth (purchased at Home Depot) on the floor and side wall of the foot well. The sheet covered the entire foot well floor, and ran up the wall much higher than the box will be.

7.I placed the wood frame in the foot well on top of the fiberglass sheet. From here, you can see what will need to be coated in resin. (the bottom, back and outboard side)

8.With the frame in place, I mixed a batch of resin and applied it to the fiberglass with a disposable paint brush. (wear a respirator, glasses, and gloves.) After 30 minutes, it was hard and the frame attached to the fiberglass shell could be removed from the car. The box now had the general shape. I trimmed the excess fiberglass cloth, and wrapped it around the edges of the particle board where fiberglass and particle board met.

9.From here, many more coats of fiberglass cloth and resin were applied on the inside (approx 5, so it was getting thick and solid)

10.Next I custom cut the top out of particle board, and screwed it in. After the top was secure, the box had its final shape, so I checked to ensure it fit well. After the fit check, I applied more resin to the exterior of the box and laid fiberglass on all of the wood to fiberglass joints to help seal the edges and give the box a rounded look.

11.Next I sanded the box to prepare it for the speaker carpet.

12.Glued the speaker carpet to the box.

13.Calked all of the joints inside the box w/ silicone calk.

14.Installed the speaker.

Your box looks sweet. I did something similar with 2 JL10W6s with 0.35 cf airspace each woofer. It was a real tight fit, but well worth it. I made it so two people can still barely slip their feet between the box and the front seats.
