What is the tuning of the 3.25 ft^3, and how much power are you running?

^^^ Ditto whay Brian said

louder No

deeper Bass Yes

SPL ( loud ) small box ported High

Booming Bass Big Boxx ported Low

Just my .02

3.25 tuned to 38 Hz is going to be a loud box up around 40-45 Hz. what are your goals? If you are looking for more low end, I would try for 4.5 ft^3 tuned to 32 Hz.

What type of music do you listen to?

I LISTEN MAINLY TO RAP HIP POP. IF I MAKE THAT 4.5 BOX FOR TUNNED AT 32Hz WOULD IT BE A BIG DIFFERENCE FROM WHAT I GOT NOW?? THANKS A LOT BKOLF04 UR VERY KNOWLEDGEBLE PERSON. HOW MUCH POWER CAN MY BL15 LOADED TAKE??

Don't go over 4cuft. IMO.

It would just hurt the sub more than it would do good.

4cuft tuned to 30hz, with 70sqin of port.

They are low machines.

so 4 or 4.5 cuft of volume on the box?? what about te perfect amp? how manny watts?

Depending on the coil configuration you have the resonant freq of that sub is 34.5 Hz or 35.1Hz, you'd be better off tuning the enclosure to that instead of 38Hz. That will make the enclosure more efficient and get more out of the power your giving it.

would a 15" BL fit in a civic trunk? or would it be smart to just get like 2 12"

go get a measuring tape :wink:
