Need to change my Sub, give me hand choosing the new one!!

[mledez]

Hi,

I drive a 08' Sedan without folding back seats... I was running Alpine Type R in front and back stage and Image Dynamics ID12D2V3 on the trunk...

I decided to change my front stage, the last week I installed Focal Polyglass Components and WTF the SQ is amazing, but now I need more bass because the focal go very very high...

All my gains are set using a velleman scope, so all the signals are very clean.

I have Eclipse XA-4000 125RMSx4 @4 for front and back stage and Orion 600D 600x1 @1ohm for the sub.

There's a problem in the sedan without folding seats, because the cabin of the car is tried to be isolated from the trunk the air movement inside the cabin s very poor compared with HB models, so I decided to remove the seats and make a test... And Woow the response is a lot better but not enought to compensate my new vocals

So I decided to buy a new Sub or a new pair, I'm comming for a very Musical Sub so SQ for my is very very important, but of course I need to get loud enougt to match the focal comps

My options are 1x JL 13W6v2 running about 450rms or 2x 12W3v3 @ 300rms each.

Please give me a hand, my budget is 400$

I build two Enclosures for the sub, Vented and Sealed (carpeted), using any box the bass is not enough "Without the focals comps, the sub appears a lot enough"

Oh, too much text (Sorry for that my english is not good)
Remember the question, Sub combination 400$...
My options JL 13w6v2, 2x 12w3v3... give me yours
