Guys I just got 2 of the older style Powerbase evo's. They have the blue cone and chrome baskets. I email powerbase and they recommend this

Subsonic Filter Setting If Applicable 20-25 Hz 20-25 Hz
Sealed is optimum sealed is 1.25 and large is 1.75. with 16 oz of polyfill.
I need help on placement of the woofers and port. I really want a slot port but may have to do it on the side. I have about 35" from side to side and maybe 17" in height. I'm not looking to fill the entire trunk up either with box. What should I do. Of course I want it to be loud as possible. I also have a 60/40 folding seats in the rear. I'm afraid a slot port will take up so much cu ft inside I might have to do PVC 4".
