btl 12", 15" or 18"

how much of a difference is there for output from a 12"btl to a 18",, i have a bl15 fully loaded and shes getting 900 rms, im debating on getting a btl and sell my bl15 but it would cost a lot to buy the btl and get a huge amp for it. should i just buy a bigger amp for my bl or get the btl, if the btl is really that good it ill save up and get it what yall think thanks.

What box do you have your BL in now? Feeding your current setup with more power will also increase output.

MY BOX IS 3.25 CUFT tunned at 38hz so should i just get a bigger amp then?? i can sell my amp and get a bigger one.

I have a rf p8002 it does 900 rms its not bad but i know i can get something better.

you should start on getting a bigger amp for that BL.

though your box also seems a little small and tuned pretty high there.

3.25^3ft is nominal. It is tuned high though.
