2 6" round ports vs 3 4" aeros?

[GI JOEY 10+ year member]

I dont feel like he 3 4" aeros will be enough PA for my build vs 2 6" pvc. I increased the size of the box to 5.6 before port disp.

Anyways only having like 30 something of port area just doesnt seem to be enough. I can still do a slot port but I plan on either side firing the ports to the drivers side. I also thought about doing a single 6" on either side to even the sound out in the cab. I'm not sure if I will do that because I want to get a decent number on the mic. Box is under a lifted seat.

I guess I will just build a 6X12 slot port. Thats plenty big. That should get me ove 14 ci per ft.

Go with 2 6" aeros.. or 1 10" .... The less ports you use the better.. itll reduce air drag...

I went with the 3 4" aeros. The box is gonna be just about righ. I decided to go with a little less port area to keep the subs from unloading too quick on the low lows. I am only at like 7 ci per ft from the aeros which is just barely under the average. If it sucks I have plenty of mdf and I can try other designs.
