2 15 Treo Subs in 92 Cavalier

I need to know if i would be able to fit two 15" treo subs in my little 92 cavalier trunk. I am going to build a custom sealed box made of 3/4" MDF. I also would like to know what box volume you would recommend for the subs. I am buying them used from a friend, and they are a few years old, so i don't know much as far as their specs go. Any and all help is appreciated.

I am sure that you can fit 2-15's in the trunk. It will be tight. You'll want to build 2 boxes though, easier to get in there. Can't help ya on specs though, I've never heard of them. 

what model of treo they are? TSX? did you check with treo self, send them a e-mail, because on their website they don't have the recommended enclosures yet for their subs. TreoShaking The Neighborhood

I have checked on treo's website, and they look a lot like the TSXs but they are about 4 years old. The new TSX on their page says they are optimized for small to medium sealed, ported, and bandpass, but i don't know how small is small to medium for fifteens.

I had 2 12"s, in a 4.5cu ft box in my 93 cavalier.. Why don't you just take some measurements, and start experimenting with WinISD ?

4.5cu ft was total for the box.. I didn't mention per chamber :) It took up the whole trunk, with the subs mounted inverted.
