you need one box with one large port.  if you want max spl for your truck, you need to build a box for that truck specifically.  the box makes the BIGGEST difference in the way a woofer performs."If a man made it, another can modify it...it just takes some thinking."

"If you ask questions, you're a fool for 5 minutes; if you don't, you're a fool for a lifetime."

to get the highest spl at the dash, measure the distance between the top of the dash where you usually put the meter mic back to the place where the box is going to be at.  take that measurement and mutiply it by four then that is the wavelength you need for max spl.  take that wavelength and determine what frequency has that same wavelength and build a box that is tuned to max output at that frequency and play only that frequency (or one of it's octaves) at competitions.  that will give you the highest spl reading possible in that truck.  also dynamat or similar, and brace everything you can.  any vibration that occurs causes loss (i.e. glass vibration, dash rattling, doors flexing, etc.)."If a man made it, another can modify it...it just takes some thinking."

DO NOT CHANGE ANYTHING BUT THE BOX...the amp and woofers you have are fine.  you are not getting the max from them yet.  trust me, i have helped acrue over 100 trophies in spl competitions at the shop i just left 3 days ago."If a man made it, another can modify it...it just takes some thinking."

"If you ask questions, you're a fool for 5 minutes; if you don't, you're a fool for a lifetime."

when i get around to it i'll pull out my work laptop at calculate the wavelength and frequency at that measurement and even tell you the port size and box size you need to obtain that."If a man made it, another can modify it...it just takes some thinking."

100 is a hyperbole...realistically it's about 40 or so with my now hated ex-boss Larry Todoroff with Team Kove.  24 12's in an astro van with 16000 watts.  some local shows helped accumulate that number."If a man made it, another can modify it...it just takes some thinking."

okay.... just let me know what 2 do i got a picture of the way its setup on here just take a look.....and the flex is vey minimmal in my truck vibration 2....plus il be getting started on a new box in the next week or 2...

What type of truck are you using?    I have a few designs laying around that were all good for over a 150, but at a much higher frequency (Not streetable)   If you would be interested in something like that I can try to help, but need to know what type of truck it is first2009 0-1000 Trunk WR 154.0DB 2009 1001+ Trunk WR
