Do ports have to be facing the same way as the subs?...I'm trying to port my box here but I have a reg cab truck and my box is narrow and long 60 long 17 high 8.5 ave depth. The minimum port I need for my subs is 4.5 dia which makes it 23 long. So I got no choice but to put the port lengthwise(facing cab corners). My box has only a few inches on each side to...:mad: ...
Is this gonna be alright?

you dont want the ports to be obstructed... just leave plenty space open at both ends of the ports

Can you put the port on top and use an elbow to bend it inside the box?

thats the prob though...I can't have extra space...my box barely fits behind the seat...I'm runnin 1.79ft3 per sub sealed...and wanting to port cause my subs flutter...got to much air space. my ports have to go that way...

I kinda sorta wanna know for sure if I can use an elbo...Cause I'm gonna rip to town soon and pick up some pipe so I can do it this weekend. It should work?

elbow pipe will work, nothing wrong with bending ports...

hell, the port system in my old box for a single '12a was a labyrinthine (sp?) tangle of MDF, hehe...needed to stuff all that port in to drop the tuning to 26 Hz...

once i saw a pic of an 8a in a small box, the port was a 3" PVC pipe that came out of the box and had an elbow in it, hehe...the thing looked like a steam engine or something with an exhaust pipe...

elbows are fine, i used 2 of em in a box for a 12 i built and it sounded great. It had 2 3" ports and both were bent with the elbows.
