I couldn't figure out how to get it to work right with that sub. It just sat too close to the carpet, and the sub didn't like it. I ended up destroying the rubber.
jared, He did tell me he HAS to build the box to clear/allow 2" of excursion.
Now that i have the subs in i see why!
He also did mention about the seats firming up alot, but i could raise the seat if needed. I told him just build it and if i need to raise the seat a little i will
So after waiting 2 weeks and no sight or word on my box I decided to call. To my surprise no answer, then minutes later i received a call that apparently I missed. Also got a text message from them apologizing for them missing my call.
I called back, he said my box will be shipped tomorow. A+ customer service so far. Haven't dealt with many where they will call back without a voice-mail much less text.
I have the 06 LD CC subthump box and stuffed it with 2 Sd-2's.
I removed the rubber ring on the magnet and opened up the recess in the box 1/4" on the sides.
The sd's dropped right in.
I also had to raise the box 1" to clear the surrounds from the floor.
Here is my thread over at GMF.
