I'm getting ready to start building a box for 2 Sundown Ev3 12s that should be here later today and figured before I possibly ruin $40 of 3/4in MDF that I'd check with the CA hivemind first. Initially, I was wanting to build a tline but after banging my head against WINISD/Hornresp and getting no where, I gave up and simply copied the bassahaulic refrence design SA has on the Ev3 page. The only change is adding a mirrored chamber on the port side, that way I wouldn't have to do any math for port volume (and have a box built far sooner than it would take me otherwise).
Other than being less efficient than a smaller footprint single chamber ported box, does this design have any critical flaws? Whenever I get a better grasp on WINISD and Hornresp I'll build a different enclosure, for now I just need something to throw the woofers in so I can finally have some solid bass in my ride.
Misc details:
2000 Astro van, both rows of seats removed so space is a nonissue
Pioneer avh-x2800bs headunit
Garbage tier JVC coax 6.5 front door/4x6 rear pillar speakers, JBL stage 6x9 for the dutch doors.
(soon to be installed)
2x Sundown Audio Ev3 12in d4 woofers
SFB-2000D amp
1/0 Power wires, stock electrical (big 3, 2nd battery (if the case repair holds up) and AD244 swap will be on my next day off late next week)
