Oh, if you have not pulled your trunk liner yet, you will find the well has a lip to it. Cut your lid large enough to fit under that then you only have the rear of the well to worry about sealing. If you are careful enough in you measurements you can cut the MDF tight enough to the contour that when you carpet it, you pretty well sealed it.

 

The liner has been pulled but not cut. Matrix- How "tight" does your sub sound?

so matrix, are you just running that sub free-air then?

FFSkip, maybe that's the better way to go? never mind sealing everything, just seal the edges and use a good free-air subwoofer?

 

I am using my relatively new(August) subs I have - JL 10W3v2's.

 

I'll try and help here a little... As I'm reworking my system as well right now with the help of my brother.

If you use the entire space in that well you will have WAY to much air to move around. I suggest that you make a fiberglass box that can be taken out fairly easily. That how my box was last year. It was a sealed box with the wire coming out the side all epoxied in with connectors on it so if we needed to remove it it was very easy.
Here's what it looked like last year:


My brother took a 1.0 cubic foot of packing peanuts and dumped it in the well and it didn't fill much... so you really don't need that much space for a sub to work properly. You don't want to Dynamat the inside of the box as you WILL lose the sound coming from the sub sound deadeding ya know

 

Thanks, Mr. Knight! Based on JL's site, I need between 1.2-1.8 cubic ft of air. I am using two subs. I'm going to do the "styro"-thing just to say I've done it. I'm also going to check this enclosure- my current one:

 

That looks good, a little big, but the paint work is nice

 

Thanks. It was not meant to be on top of the liner. It sits a little lower than the picture. Not sure if it's too big air-wise, but it is tall. Can't get the clubs in the trunk. That is one of the reasons for the change.

Just found out how much I paid to have that enclosure built! :fallsonfloor:

 

Buy a 50 lb. bag of kiddie sand at Toys R Us for $2.99, line the well with plastic, fill with sand, drive for a few minutes to vibrate it solid, dig it back out and measure. Using sand, you can vacuum any grains that left the plastic.

If you need less space than the well offers, measure out the needed amount of sand, make a basic mold of the well, fill the mold with the measured sand, cut mold to level.

As far as LEDs coming from me, you'll be waiting a while (no jokes from the peanut gallery!). I have yet to sleep as I've been working on the third revision of my business plan nearly nonstop since 11:00 p.m. last night. Without that, I don't get funding and products don't get manufactured. The good news is, once that happens, I can send out as many orders as I want immediately, no waiting list.
