Port Question

[coolbreeze]

OK, I figured out how to calculate my ports, port length, tuning and everything. But I have two questions. One, I want to port the box through the rear deck, so does adding the additional external port up to through the deck change my tuning. And two, should I face sub to the taillights or seat.

I have a single 12" CVX in a Mazda RX-8. Amp is Kicker 750.1. Any other suggestions on the box would be appreciated if there is a better way to do it other than ported. I thought about bandpass but I'm still confused on that formula.

Max parameters because of trunk opening are 29"w x 13"h, and roughly 10-15" deep.

Yeah extending the port will affect the tuning.

Your best bet is to start the port at the deck and only make it as long as it needs to be. The port doesn't have to be inside the box

OK so my port should be 5". I start at the deck, and from the deck down to the should stay at that 5". Meaning it would only go down about 2" into the box.

One four inch aero port 10.25 long for a tuning of 35 hz in a box 2.25 cf after sub and port should work for you.
