u got more space than i do with my 8'*. lol! good thing u went sealed, JL has a part in the owners manual for the 13TW'* that says in bold print NOT RECOMMENDED FOR PORTED ENCLOSURES, lol. prolly do to the short voicecoil. made for punchy bass not deep, move alot of air bass.

tune it same as the 10W7?

use the specs for the 10w7 just to get it in the ballpark, just showing u what adjustments to have set at 0. and approx on the others... make sure to not use any bassboost. and if possible use a gasket between the sub and box to make a 100% seal, u got to maintain 100% control of the movement of the cone.. the 13TW5'* voicecoil is less than a inch tall, unlike most conventional subs that have a voicecoil of 3 or 4" tall.

when you say when its set at 0 you mean the subwoofer level in the HU right?
bassboost is off, just out of curiousity why is it bad to turn it on?
and the seal is there between the sub and the box

i mean the bassboost on the amp... that diagram i showed u shows u how to set most of it...ur supposed to set all eq curves flat, but thats unrealistic. I got a descent curve on my headunit, and my setting on my amp are set modestly.

yeah my amp doesnt have the Bass EQ, i have the GMAX, the one they have is the 500/1v2

Never knew you bought one of those panels..Looking good buddy~!

that gxp thing thing is cool

i dont know which got me more excited..that GXP thing or the subs!

nice junk in the trunk! lol
