Building an under-seat box for a 10" Fi BL. It'll be powered by my JBL GTO 1201.1 that I had with the 15" Q... It will be ported, tuned to around 33-34 hz and has around 1.2 cubes after port/driver displacement.

The BL next to the Q. It weighs maybe one lb less than the Q believe it or not... it's a beefy little bastard. I bought it off of here from slam (http://www.caraudio.com/forum/member.php?u=23494). Great guy to deal with!

Box design by a guy on a truck forum I'm on... I changed the measurements up a little bit, but his picture help me to get a really good idea of what I wanted to do.

Just got all the pieces cut tonight and mocked it up... I'll finish up the box tomorrow other than carpet (waiting for it to get here).

Great little sub there. 1.6@35 with a pair of 3'' aeros worked best for me.

Box is done.

Sounds ****in amazing, quite a bit louder than the Q was in the sealed box and hits EVERY note. Sound quality is 100x better with this setup, plus I can still use my back seat. I also had to relocate my amp to the back wall. I used heavy duty velcro to attach it.

All I have left to do is carpet the box, put the grille on, and put the seat back in tomorrow...

Looks great....the BL is very underrated as a daily sub. That's impressive that it was louder than the 15'' Q sealed!

And DONE :D Sounds a lot better than the previous setup (15" Q in a big *** box that I could use the back seat with) . This setup is just as loud if not louder, sound quality is WAAAAY better, and best of all it's way more functional. Few pics...

Yeah, didn't really surprise me either :laugh: It was one BIG *** sealed box, but it doesn't even compare to the loudness or sound quality of this setup.

Haha yea the sub does hit the bottom of the seat when moving out, but the bottom of the seat is thin carpet that has about 2" of give before it gets to anything slightly hard. I could leave it like it is, however I already ordered a grille for it just to be safe. The seat is all the way down and locked in position in that picture... I just noticed the floor mat looks dirty as hell in that picture, too lol **** flash.

i'm probably going to run that sub in my s10. i have it narrowed down to the BL 10, DD 8's, or a focal 33v1 13. i'm leaning toward being a little louder than focal, so BL 10 is my first choice as of now. good to hear nice reviews.

What are the specs on the port? I see 3" diameter but length?

I love the BL so far :D Hits the lows great. It's very good with snappy bass as well, doesn't skip a beat.

3" flared port, around 11 3/8" for ~ 33 or 34hz
