Lexan thickness question
#1
ok, here's the deal, I'm planning to cut out a part of the rear deck on my lancer, and fire a 12" sub facing up, with up to 1200 RMS running through it. I'm also planning to use lexan to separate the sub from the trunk, since there won't be any obstruction between the sub and the cabin, I'm thinking that 1/4" lexan will be sufficient to separate the sub and the trunk, but still show the sub.
anyone have any thoughts?
(BTW, I already have the 1/4" lexan )

if it was part of the box, I'd totally go with the 1/2" (I may be able to get some of that free too ) but I'm thinking that since there'll be no pressure, and it'll be supported well on every side, and not be that big (10" x 22" or so) I figure I can get away with the thinner stuff...

if you could double it up, to make a 1/2" section, thats what I would do, if you have enough. I would be worried that 1/4" would flex too much, and vibrate and rattle like crazy...

I'm having a little trouble understanding this. So you want to run your sub IB, hanging from the rear deck, yet you want to isolate the sub from the trunk? Not from the cabin? Traditional IB designs are to isolate the trunk, which acts as your sub 'box' from the cabin.
Will the sub be in it's own box or be in an IB setup? If the lexan will be any part of an enclosure wall subjected to pressure, 1/4" will flex. Lexan isn't as rigid as acrylic so it could flex even more. If the flex does not bother you, do the 1/4".

The sub won't be IB, it'll be in a sealed box, firing upwards through a hold cut in the rear deck. the lexan will simply isolate the sub from the trunk, and provide protection for the sub from anything inside the trunk. it will in no way be a part of the subwoofer box.

SINGLE-VENTED BAND-PASS
("4th Order Band-Pass")
The single-vented band pass is one of the best designs for the car. It is basically a "compromise" design between a sealed and vented box with a good compromise in performance and reliability. Probably the best type of enclosure for most applications.
Advantages: small box volumes, extended low frequency performance, and can be used with very high power amplifiers.
Disadvantages: slight drops in efficiency compared to a vented box and increased box design and construction complexity.
