I think you did a pretty good job for your first build. If you are happy with the results then that's great.
I thought I'd add a little useful info for everyone to clear some things up.
People are really confused about aero's and pvc ports...aero indicates the fact that it is flared to reduce turbulence and improve airflow (on both ends). PVC can be made into a homemade aero by creating you own flares but very few people do this. Here's an example I made:
I have done testing that proves that flared ports (round and slot) outperform unflared versions. The more power you apply or cone surface you add makes the problem worse. A safe rule of thumb for calculating flare "effective length" is half the physical length; so a flare that's 2" long can be calculated as 1" of port length. It does depend on the flare radius but it's not enough to matter in most cases.
3" port =7 sq"
4" port=12.5 sq"
6"port= 28 sq"
The formula for this is just: area of a circle= 3.14(R x R)
Clearly (2) 3" ports DOES NOT equal (1) 6" port and a round port is not always superior to a slot and vice versa. Its application dependent and you need to balance box size to port area with regard to power and sub capability.
OP-sorry for a small thread jack I just thought people could use the info!
