New Sub Enclosure - Two 12's in a Single Cab

[phlowtey]

I had a single 12" sub in a pre-fab enclosure in my truck. The enclosure pushed the passenger seat pretty far forward. I had another sub so I decided to see if there was a box design that would allow for both subs without pushing the seats forward. After relocating the rear speakers into the doors - http://therangerstation.com/forums/showthread.php?t=129372 - I was able to design a box that worked. Here is what I came up with.

It is divided into two chambers. Total volume is just shy of 2.5 cubic feet.

I cut the plastic panels and the carpeted panel in the back of the truck. The enclosure is wedged under the beam across the back under the window. The amp is connected to the subs and all four speakers. Running the wires was interesting.

The enclosure is back far enough that if it is pushing the seats forward at all it is minimal.

Nice box! You don't need separate enclosures for the subs. They are fine to share the same volume of air. In fact, some times separating them will give each a slightly different tuning frequency. Most likely you'll never notice and the divider will help by adding plenty of bracing and reducing flex.

looks good but I prob would have mounted the amp lower (like between the subs) so it is out of view as well as out of sunlight

The amp is 7" x 2" x 19" and has a fan on the bottom so finding a spot for it wasn't easy. I don't really like where it is at but there were not a lot of options.

what subs and amp are you running? the subs look like older fusions?

The system is a little hodge-podge. I bought the amp and just used stuff I had laying around. The subs are Fusion Encounters, around 10 years old. I have two pair of 3-way 6x9's. One set of Pioneer's and a set from Soundstorm. The amp is a 5-channel FLI. Overall, it sounds decent for what it is. I haven't had work for over three years. When I get regular income I think there are a fewchanges that need made.

i had a pair of fusion encounters the newer ones and they sounded like crap. i will never buy fusion again lol. and they were in a sealed box so i know it wasnt all box. my new JLs sound great in a box i built.

My two older brothers ran a car audio shop for a few years around 2002. It seems that a lot of companies that were decent then are hit or miss now for quality.
