Triticum Agricolam Posted April 21, 2016 Report Share Posted April 21, 2016 That's not how ports work, as you add port area they all need to get longer, not shorter. So if you have one 4" port 24.5" long and you added a second they would both need to be almost twice as long.

Or would I still need the 24.5 for 32 hz tunin 2003 Chevy Silverado Reg Cab. Rockford Fosgate 500a2 and Kicker ZR240 each on their own 12" Kicker Comp S. Small, but everyone's gotta start somewhere.

Joe X Posted April 21, 2016 Report Share Posted April 21, 2016 Yes if you reverse mount the sub that 4" port would get to be a little shorter fully external or the same size but partially external, that is, you could place inside the port for an amount of length that equals the driver displacement of the sub or about 12" outside of the 24.5".
