Box question

[d-nice88]

I built a box that is 9 cubes gross and makes my fi bl subs sound awesome. My question is that i wana upgrade to the new sp4 or btl models and was wondering if the box i already have would be ok or would i have to rebuild?

Anyone?

Its impossible to answer that question when the only thing we know is you have BL subs and the box is 9 cubes gross.

What size subs are they? How many do you have? What is the net volume of the box? What is the box tuned to? How much port area does it have? What amp/s are you running? What vehicle is it in? What are your goals for the system?

Dooh! Your right triticum my bad its 2 fi bl 15's in a slot ported box tunned to 32 hz in a 95 gmc pickup running off an audio legion 3.5k. Will be adding another 3.5 k and 2 more batts for the sub upgrade to either the sp4 or btl's. Just wana get louder. Love my bl's but i think its time for an upgrade now

What are the dimensions of your port? I would guess that your existing box would work, but the port is going to be too small for the amount of power you want to run.
