Vent pole spacing needed?

[oxsign 5,000+ posts]

So I took the rear seat out of my crew-cab, re-drilled the seat brackets (again), got another 1" out of it. So now I've moved the rear seat up a total of about 2.25" to try to get these subs to fit, lol. Now the sub clears the seat by about 3/4"-1", but the rear of the sub (magnet) is up against the back of the box at an angle. I have about 3/4"-1" between the vent pole opening and the back of the box. How much more do I really need?

Should be okay. but it the boxes flexs AT ALL... you'll get noise from the sub motor itself hitting.

Had it happen on a tight box before...

I'll keep that in mind thx. I do plan on using 1" dowel rods for bracing, maybe that will help some.

Mabye get a piece of foam and jam it in behind where the magnet is going to hit the box too...

yea dont let the motor touch the box. mark where it hits take a router and take out some of the mdf then resin there...

Won't you gain 3/4'' once you add the front baffle???

Nope, you'll see after I post pix. The front is sitting inside the "sides, top, & bottom". //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

line the back wall with neoprene as a precaution?

I would do as posted above and just sand down 1/4" or so where the motor is currently hitting the back. This is what I had to do in my truck box and it worked fine.

how much of a gap should there be inbetween the pole vent and back of box? atleast 1/2" or so?

im cutting it close with one of my 18" DP's in my single 18" ported box, looks like ill have about 1/2" of airspace behind the motor. there is a brace going from baffle to the back though, so it wont flex and physically hit the back, i just want to make sure there is proper ventilation. there is a gap inbetween the motor and basket anyways, probably 1/4", so that should allow for sufficient cooling i think

...not a good idea, imo. When you slide in the front baffle, the sides, top and bottom will just scrap off all the wood glue.
