my new system can i hit 150?

[maljr1980 10+ year member]

ok i pulled a 145.3 on a termlab on the dash last year with 3 12" kicker cvx's in a 3 cube sealed box stuffed with polyfill off a hifonics 2010d brutus. i drive a 2006 chevy trailblazer. my new setup is 4 12" L7's in a 6 cube sealed box being pushed by 2 alpine pdx m12's, which birth sheet 1320 and 1340. so ive got an extra sub, square vs round working in my favor, and probably 800-1000 more watts. running a big 3 and 1/0 gauge back to a kinetic and 8 gauge wiring to my subs. what do you guys think i should score, and should i polyfill this box?

well i think the most obvious way of you hitting 150 is to make a ported box, you'll def. gain a lot of output

no pics sorry, i did have them wired down to 1/3 of an ohm though, it was to music and scored 145 at 42 hz

heh I'm thinking about using my MA Audio HK602sx to power 6 type Rs in 1/3 ohm loads at some point. Need more trunk though the Cavy just won't cut it.

Blah, I don't see it personally.

maybe on the AC mic

cant do a ported box, have to keep my stuff on the d/l and hid under the cargo cover, and i personally think sealed sounds better and hits harder, may not vibrate and meter as loud but sounds louder imo

You can't do a ported box but you have space for 4 12' L7s? Have you ever heard a ported box?

Build a new box.

~7.5-8cuft net, 3-6" flared ports. Subs up, ports back. Have the ports about 6" from the back hatch.

Start w/ the ports full length, and cut them down as you test. (you will likely peak out w/ the ports ~10-12" long)

When you get to your peak SPL w/ all 3 ports open, your set for competition. The beauty of using 3 ports is this....plug one port (center port) and play it daily //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

It will tune FAR lower and sound good for daily beating.
