If you want to have a chance of being in the mid 150's, then you better go ported.

Plus you better invest in a shit load of MDF and a TermLab

ok but does anyone no how large th eport cut out should be? i was thinkin of making it 4"x10" in an 6cube box im makin 2 6cube box's each one tuned to high 30's.. yea and im lookin at near 4 sheets of mdf just to build these 2 boxes.

id honeestly, put more port area, and tune higher. if ur goin mid 150's ur gunna need a lot of port area and prolly mid 40's tuning. if not 50's

the largest i think i can make each port is prolly 4.5x11.5 unless i made one huge @$$ box an braaced it really good which i dont want to do because it would be a pain to install an all. so do u think 4.5x11.5 would work if i tuned it to 38 or 40 i still want it to be able to handle daily music an not sound like an wet fart.

u got the wrong subs if u wanna hit 150's and sound good.

I disagree...

a change in woofer you'll want the Sd. If you stick each driver in a 3.25 per driver, tune to mid 40's you'll hit high numbers, but for more daily souind, tuning to low 30's is better...

Kicker can sound good when loud...Why does everyone think they have no SQ?

You must be new. That's an old old arguement here.

Because they're kicker and there square...so they must sound bad

Because they're kicker and there square...so they must sound bad My opinions of Kicker's square shape is based on physics, not ignorance. Sorry.
