Tell me if you like or dislike your under rear seat subwoofer?

[gwb72tii]

Until if and when I get to building a proper 10" forward firing sub/box mounted in the trunk, I am thinking of one under the rear seat as a temp solution. 
Or perhaps a longer term solution depending on your opinions.

Do you like how yours performs?
What size?
Good enough?

As I've mentioned in other threads, when I owned my last e30, I had installed a "Lukebox" made by a forum member that bolted in the trunk to the sheetmetal behind the rear sear backrest. There was an opening in the e30 behind the rear seat armrest that conveniently allowed a sub to fire through the back of the rear seat into the car. The end result was the best stereo system I've heard in any car, newer or older. I may make my own for my 535is, but maybe not.

TIA!

I've made two:

Here is version 1. It was OK. Sounded better than it looked.

Here is version 2 with a larger driver and a larger ArcAudio amp It's better and I have no real complaints, although it does struggle a bit with one passage from The Planet Krypton from IASCA competition tracks.

If I can get a tuning session in, I'll post the response curve. 

If I find time and money, Im going to take another run at getting that JL monster to fit.
