im open to to anything to let me know what you think i should to

3 lvl3 15's or 2 lvl 4 18's and in what box

[Namosh]

I doubt you have the room for a t-line with 3 15's. I had one with 2 15's that took up most of the bed of my truck.

I'd say just go with a 4th or 6th order bandpass. My current box is 3 15's in a 4th order and it is the best sounding and the loudest I've ever had in my truck.

2 18's, see my first build log.

There's no way you're getting a 3 sub t-line in your bed.

T-lines are only great for low power setups as they offer a way to use the backwave of the sub constructively without any interference. IE if your'e gonna put real power too it, you need a suspension that makes even AQ subs look like floppy jokes. (it takes 2 hands to make a brand new AQ sub's cone move)

Stick to a 4th order bandpass. Both subs you mentioned will work great.
