So i love my two fi ssd"s, and i wanna get two more and another amp of the same...

I was wondering if this would work

12" high, and 38" wide, and 30"long

their upfiring with aeros...its in a trunk car, so the subs would be facing up, and port into cabin or rear(would this work well?(the faeing up part))....not sure on size of aeros you probally would have a better idea? thanks

tuned to 34hz btw.

PS heres my old video of system as is

did you just guess what would be best for all 4 drivers in one box? you need to calculate port area, volume, etc. dont make a box specfically to fit just the drivers. tuning is more than just hertz. it has to do with internal volume, air space, etc. considering as much flex as you have with those 2 12's i would suggest selling them, and get an 18 in there if you can or two 15's. if you have room for 4 12's you could properly do one 18" driver and get pretty **** loud. i would try two 15" BL's if you want to stick with FI. just my 2 cents

yah im trying to sell them but idk to who?
id like one 18 but could that be louder than two 12's?
like one btl?
ik thats a general question but still...

put them for sale in the classifieds section. keep it updated. try ebay, some audio shops might buy it from you if they sell used woofers, usually a low end audio shop. and yea one eighteen will get louder than two twelves
