Okay hopefully this weekend I'll get to building my friends truck box for his f250 crewcab. Box is going behind the back seat and we added a few inches by flipping the brackets that hold down the seat.

They are 2 10" l7's which will be run of two zx750.1's.

The box comes out to 3.94 cu ft gross, i don't have displacement for the subs.

I would like to use 4" aero's, If I use 3, 4" aero's it would be about 38sq in of port. And if I tune to 34hz each port would have to be almost 23" long and the height of the box is only 17". . . .

Here are the dimensions for the box.
60" wide
17" tall
11" deep on bottom
7" deep on top.

Double baffle for front, and port's facing up.

1. What is a good amount of port area?

2. Is two zx750.1's for 2 10" l7's too much power?

3. What is the displacement for a 10" L7?

You could get away with 2 4" aero's (or 1 6") if you desire. This would shorten the port length.

They will take the power if you don't abuse them. Use good judgement when playing.

Check the Kicker site, I know it tells the displacements where the specs are.

Will this work on teh ends of 4" pvc?

Those will work, but I'm not familiar with that style. Most people use the PSP brand ports.

I know but they are $$$.... oh well i'll make my friend just get them. I had a box with 3 10's and a 8" pvc port and no port noise, thats why i wondered.
