I will soon be running a fully loaded BTL 15 in a 4 cu ft ported box. Which tuning would be better SPL wise, 45, 48, or 50 hz? I know it is a bad question because it varies, but what has been a good SPL tuning most people have been using?

Thanks

If it would be best to build a bigger box would a 4.5 cu ft box after displacements be a good volume for SPL? Thanks.

Honestly,

Theres no certain tuning for "SPL"

Its watever your car might like.

Also same with cuft. Just gotta build and test build and test.

All of that comes through testing...you've got to figure out what your vehicle likes to get 'maximum' spl.

I know everything does revolve around testin, but will a bigger box allow me to send more power to the sub and get louder in the process from moving more air? This sounds like a noob question but ive never been good at determining SPL boxes/tunings and I usually just go with the manufactuers recommendations.
