Awesome! How much height did you get under the seat?

Max dimensions for a box under the seat are 56” wide, 13” deep, 8.25” tall on the front and 5” tall on the rear of the wedge. This is without removing the storage pockets or doing a seat lift. With your all weather mats, you may only be able to get 8” out of the front for height.

I have (4) downfiring 8’s right now in a sealed box, but am working on plans for front firing, ported for the (4) 8’s. Amp is mounted behind the seats.

Hope this helps you.

This is about right. My box is 34" wide (essentially the width of the driver side back seat. I was able to go deeper than 13" by removing the plastic shield under the seat - so was able to add an extension that is 26" wide and about 6" deep and tapers from about 5" to 3". You can barely see it in the bottom picture but this back part of the enclosure is the port - it is about 5.5" by 2" and a little over 17" long. Also there is room under the seat as the bottom of the seat is not solid - I was able to add a "pop out" (square piece on top of enclosure) to allow use of a deeper woofer.

Thanks for the replies. It’s looking like forward firing will be a tough challenge as well. With in 8.5” or so of height and a cutout of 7.5 required it’s gonna be close. I might have to consider down fire with a bump also.
