jghs83, have you tried opening the little 'ski hatch' in the rear bulk head and see how that helps output on the subs? I have a feeling you may be 'strangling' the design with the small opening...
It might not help...but generally 4/6th order bandpasses like to be vented 'into' vehicles with atleast the same size opening as the 'mouth' of the enclosure...

Some quality looking systems here
Bassboy, the opening is only ever so slightly smaller than the port of the sub, it doesnt sit flush with the bulkhead so some sound ends up in the back, plus the cutout was intended for a single kicker l7![Grin](https://passionford.com/forum/images/smilies/icon_smile.gif)

We built this earlier this year for a disabled lad that wanted to compete in the EMMA series of competitions.
It's a pug 107 and initially i designed it with 6x15"s but the quality of the kit is shall we say questionable. We rebuilt it for the european finals with only 4x15"s and had the amplifiers tweaked to produce power closer to the stated figures.
Personally I can't be arsed with it all anymore and have a completely standard set up in my own car but I do still like sitting in a car with a big system.

![](http://i421.photobucket.com/albums/pp293/sandy9911/2011-08-13203949.jpg)
altho i have since taken it out of van and put it all in my 306m while im fixing van. but the plan is to have 3 or 4 of those sub cabinets if i can fit them in, then 12 or 16 6x9's or components

Here is my ford ka2 which i brought back in feb 2000 when it was 3 year old back then it was standard being single a began modifying it with kit wheels and a chunk of ice from ice direct it had a kenwood dvd head unit running 5.1 surround sound dab kenwood aerial all the speakers and amps are diamond audio items last time it was checked it was 160 db enough to blow the window.
It also had a split charge system and uprated alternator
The system was built and done by me at home in my drive with the help of my now wife but then my new friend that was 10 years ago i am now married and have your 11 week old son
