Back Ground: I want to have a functional third row.
Sub -- Diamond D312D4
Amp -- Alpine M350 -- 350rms @ 2ohms
I was going to build a slot ported box but I would rather build a box using 2-4" or 3" round ports firing up with the sub downfiring. Diamond recomends the slot port but would this work. I know that I would need to router the top of the ports.
Gross cubic feet -- 2.26.
Length of single 4" would be 9.30" for 35 hz. Can I split this in 2 for 2 - 4" ports at 4.65 inches each or run one single 4 inch order at 9.3"?
Any feedback is appreciated.
