Box size and wiring

[mkinnunen]

Hello,

I bought this box because its is a 4th order and cheap. It is installed in the back of an exposed (always open) blazer.

And some DVC kicker CVR 12's

Hooked up with Orion 2250 sx bridged 4Ohm.

How do I tune the ports and at what frequency?

Should the speakers be out of phase to help with the small sealed chamber?

I have the room to run the ports outside if it will help.

I'm not looking for competition grade just reasonable SPL and quality.

Any suggestions?

Thanks,

Michael

bandpass unless tuned perfectly will not give you any reasonably good results

So then the question is: what can I do to make it the best it can be?

How do I find out if the ports are the correct length and would a port in the sealed section make a 6th order?
