Subwoofer Installation

Here's my old install that I was working on - apparently, I made a few poor assumptions....

Because of the problem with not having a spare tire well, I was left with three options...

1. I could use a "regular" mdf box
2. Try to squeeze them into the sides of the trunk
3. Use an I/B alignment

Option 3 wasn't possible, as my subs, the IDQ's, are not well suited to infinte baffle installations.

Option 2 would require the fabrication of two totally different shaped enclosures. They would be tough to match in size and to have them look symmetrical. It would also cover the tail lights, the trunk lights and the battery.

Option 1 was not a popular choice. I hate giving up fold down seats and retaining as much trunk space was a goal.

What I decided to do was to face the subs into the cabin, and use a medium sized sealed enclosure.

Facing the subs toward the back seats would allow me to fire them through the center arm rest's ski pass through. This should keep rattles to an absolute minimum - and the less weight I can add, the better.

I had this box built by Mr. Marv. What a craftsman! He builds great boxs at more then reasonable prices. This enclosure is higher quality then I could have ever done at home, so I was happy to pay for it. I can't stand not building things myself, but with these results, you can't argue with my choice!

As you can see perfect joints and no need for silicon. The box is 0.85 cubes gross per sub and is built from 3/4" MDF. The baffle will be set back from the seats a few inches so that they are not "choked"

Wow, that is awesome. I'll definitely use this as a guide if I decide to go with the M3 over the 540. I like how the battery is in the trunk. Lookin forward to see the final touches.

The sub box was secured by some brackets from the top of the box to the rail that frames in the fold down rear seat opening. The amp rack was secured using the frame rails that run along the trunk, and the rack was attached to the box with some brackets.
