sinister-kustoms

The IDQ v2's are killer subs as far as SQ goes. I've had a few over the years (still have a pair of BNIB 12's) and absolutely love them!

The reason behind the blow through is so I can keep all the seating.

That's not really going to work either. I'm running a Sundown SAZ-3000d on four 12's, and want as much port area as I can get. The Sundown would take up over half of the available area. I'm starting to think roof mount may be the only way to go without too much compromise. The only trouble there is running four runs of 1/0 gauge up the C-pillar and keeping it tidy.

There's no room under the back seat. These trucks have a raised floor in the back to make room for the gas tank. Would prefer not to put the amp in the bed. I'm in New Zealand, where we have an almost sub-tropical climate so I'd like to keep it as sheltered from the elements as possible, not to mention would-be thieves. I'll be making the box using treated timber and have a tonneau cover over the bed. Believe me, I've thought a LOT about all the options.

It's just fabric of the back of the seat frame, but I want to mount the amp (SAZ-3000d) to it, so there would be a large hunk of aluminum fairly close to the port mouth.

Couple of questions for those that have done blow-throughs. This is the back seat in my Mitsubishi crew cab. If I were to mount my amp on the back of the seat (where the sub box is in the pic), would that restrict the air flow in to the cab when the seat is up? Also, in regards to the tuning theory of building the sealed section, measuring peak and tuning the ported section accordingly - does that work with a blow through? I would have thought if the cut out is smaller than the overall cone area, then it would act as a really high tuned port?

I think I just used up all my bandwidth going over all 13 pages of AWESOME! Incredible build mate, your fab work is top notch!
