Bad Decision

I tried to install two 15's behind the seat of my 2005 Dodge. I had more than enough mounting depth. However, we tried to build the box on the smaller side and it didn't work out too well. It peaked too high for my liking. We installed two U15 v2's on an SIA5000. It did do a 148 on the meter @ 37 hz. I probably could've got it to a 150. It just wasn't worth it. My box builder screwed up the driver's side cutout and the box kept breaking screws and spitting the sub out when I turned it up. I'm going to put a new baffle on it and switch to two twelves. I'll attach pics if anybody is interested.

That ***** it didnt work for you. I helped with a similar setup back in 2010. He used 3 JBL GTO 15s. Those boogers had like a 5" mounting depth, the mag was inside the basket. Sounded pretty good. He built the box, and covered it. I just helped lift it into the truck.

The Sundown U series subs that I used have about a 9" mounting depth. I'm 5' 11" tall and still sit comfortably. I did move my driver's seat two clicks forward.

Good luck with the 12s.

How many cubes was the box?

Pretty neat there was enough energy to spit the sub out of the box.

Are you going with 12" U series?

Its a shame the 15s didnt work out. I would think a good pair of tens would serve behind a single cab,or 4 sealed tens even. But thats me. Hope the 12s work out for you. Interested to see how they serve

I'm thinking two HD 12's or DC Level 4's. I might even go back to 4 - 8's. I want to buy 4 - HD 8's and put them on my SIA5000.

My 2 - 15" wedge box is around 5 cubes net with 80 square inches of port. My 4 - 8" wedge box is 3.69 cubes net with 43¾" square inches of port.

What air space is this enclosure? Looks kinda small but still looks like a good ~2.5-3 cubes per side?

It was too small for 15's.

If I remember right, 15's need like 2.5 cubic feet per sub. Then you have the port to factor in.

Depends on the 15's...I had a set of American bass 15's that modeled 4 cuft sealed and my stereo integrity do great in 2 cuft..

4 cubes sealed, for each sub?

Yep I had them sealed in 2,5 cuft (each) and they were ungodly peaky

I guess that's why I was asking since I have seen 15"s that will work in 2.5 cubes and 15" that want 4-5 cubes. I'm guessing the tuning is a bit high anyway due to the enclosure size limitations? Looks like you did a great job in trying to get it all in there though. I always hate when something goes to plan, but then doesn't go to plan at the same time :/
