Chassing numbers... 2 JL Audio 13W7 vs 4 Phoenix Gold RSDC 12

Hey guys, just as the title says, I was going to purchase some new box plans for my Mazda 6 hatch, but I came across this. What will be louder, yet still be good on music? I have been reading very good reviews for the RSDC 12s, but I don't feel like letting my 13W7s go.

Right now my woofers are in a 5.2 Ft box tunes to 32, peaking at a healthy 41HZ, doing 143.9 on music, 144.4 on tones. Being powered by an AP3000D @ 6 ohms (no electrical upgrades...)

Can I realistically expect to come close to 149 with 4 RSDC woofers powered by my AP3000 @ 2 ohms? I will get much better electrical too.

the w7 is more of a sq sub not for spl. but i'd keep it though. i am not chasing number and i listen to music. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

No

YES!

i know a few guys on the PG phorums that have 4 of those getting right around the 150 mark. Though I don't recall what amp/s they're using......

Why the hell not. That number is very attainable with that equipment.

The car is a hatch, a big one but a hatch so cabin gain can be good. New box will be 7.2 ft with 3 6" aeros tuned to 42, with one port blocked 34 for music. So, not really farfetched to think hitting 149s with 4 of this right?
