im confused about aero ports

[bgaccord]

well im going to build a smaller box for my car and was doing some schetches,but when i check how long the ports need o be for the tuning i desire,there suppose to be 26" long when my box is only 17" deep and thats to long for 4 4" ports,

[Decaf]

that means u either need to put some of the port outside of the box or use elbows or change tuning

[andym85]

and if u are only using one audioque hdc3 15 listed in ur sig, then u could probably get away with two ports...which should reduce the length they need to be

[Decaf]

how small were u gonna make it?

[bgaccord]

i was going with 3.5cube tuned at 32hertz,can i go with 2 4" ports?

[andym85]

imo yes...or just one 6" aero..which would be more port area than two fours...

[bgaccord]

ok,i think i'll go with 1 6" but where can i buy 6" port?
