After finishing a custom install (full system) in my daily driver (BMW330i), I decided to work on the FX4's system.

Heres a shot of my install on the BMW(took about 2 weekends to complete).


Now for the FX4's
This box was fairly complicated: The size has to be perfect to fit a sub with a top mounting depth of 5.875. I also had to figure a way such that the excursion of the sub wouldn't hit the seat. I also had to incorporate the cubic footage and tried to make it equidistant between subs and as close to ideal as possible. The type R 10 has a max X of around .75 inches so I will be putting spacer mounts on the box(sort of like a baffle) to allow the seat to set on and the sub to extent unobstructed. I will also be putting spacers on the seat mounts themselves. These spacers will be around 20mm and will be bolted between the seat brackets in the factory position with the factory bolts(6 in all).
This was a test run for fitment











I will have pics of all this up tomorrow if you need anymore info or ideas. I will also be building an amp rack for two Rockford Power series amps, hopefully I will be able to post those pics as well.

If you need specs IM me.

 

This looks sick man.. Nice work! I was just wondering how I could get some bass into my extended cab.

 

Sharp job man! I'd like to see how you mount those amps. I got my amp underneath my passenger seat but still trying to figure out a better place for it.

 

If you notice in the middle of the floor board, it raises about 2 inches. The width is about 10 inches and the length is 14 inches. I will be making a rack to attach to the sub box in that spot. It will be the same height as sub box so I can mount each amp on top of the other, with ventilation from two 12v fans pushing the hot air under the middle front seat.(This is with the front seat all the way back)

I will be coutersinking the amps into .5inch mdf to all them to fit in the small 5 inch depth.

Ill post pics tomorrow to give you an idea

 

That's going to be sweet

 

nice job so far! looks like you know what your doin lmao

 

damn!!!
