I just got two dc audio 12" xl m2s. I have a ford taurus and want build my box outside and slide it in the trunk. So far i've gotten my box to around 3.3 cuft. BTW im sealing the trunk off.
My problem is this: to save room from making the box so big i wanted to do an external aero port. The biggest i can go is 6" though and look how close it is to the subs.
Precision Port 6" Flared Port Tube Kit 268-354
That's the port and middle circle is the not the cutout but the inside flare diameter the cutout is just a little smaller. Also the inside line in the sub circles is the cutout the outside is the actual outside diameter of the subs.
Do you guys think the port is too close to the subs and is only one 6" external aero 17" long for around 34ish hz good enough for 2 12s?
