Need Help On Subs

[Fate710 10+ year member]

Ok so I'm looking for a new set of subs. The 15" SXs are getting old. I just got a brand new box(7.4@32hz) built and want to put another set of 15s in it or build another new box.

The subs I have been looking at are the Rockford Fosgate TRF2215s. There isn't much info on them but I've heard them in an install once and they were **** loud. Just wondering if the current box would be too small.

The box I have no is built to stay under the rear seat line of site. If I build a new box I'm going to build one with the subs and port firing forward and have the box go from floor to roof and from side to side.

Just curious if anyone has any suggestions for me.

meh i personally would keep the sx 15's maybe get them reconed from FI and just build a new enclosure.... i just sent my SX 12's in to Scott at FI for recones before meca world finals...triple stiff spiders/ flat wound coils and larger tinsel leads....

are your sx's underpowered, ported? how much money are you looking to spend

my SXs are getting 1200 a piece. They are in a 7.4 @ 32Hz ported enclosure.

Well I can pick up the Rockfords for less than $300 each so thats what I would like to spend.

Would my box(7.4@32Hz) be ok for 1 TRF-2215 w/ 2400 watts to it?
