    Port question

    Hey I was wondering about how to determine port size for two 12" subs sharing a single port. Each sub would have its own air space, about 2.00 cubic feet. If I have one port in the middle of the two subs what do I do for calculating the port length and dimensions? Would I use a calculator like this one at the12volt and put in 4.00 cubic feet for volume or what?

    Thanks for any help!


    Oh, and one other thing. :P I have a limited amount of space so how bad would it be if I went down to about 1.75 cubic feet per sub?

    It depends on the woofers. We need to know how much power, what woofers, and what sound you are looking for.

    Okay. I've got a 1000w RMS amp, but each sub is 400w RMS. They're MTX JackHammer JH55's (12") subs, I'll have 2. No hate on the subs. :P I'm looking to tune to 35 Hz but I don't have a ton of room (2000 Toyota Celica GTS).
