Hey, i recently built a box for my 2 Fi X 12's, it is a ported wedge box 4.37 cuft after port and sub displacements. I have a 4 inch ,"precision port", flare port and is 6 inches deep. The problem is that the sub closer to the port moves more and im thinking that i could get more out of the subs if they both had the same movement. A little confused.. i was told that it would be louder if i would have divided the box and but two separate ports, one on each side rather than one on the passenger side. By the way i have them on a Autotek MM1000.1D

just gonna throw out the most basic thing here: have you double checked to make sure a wire on one of the coils hasnt come loose after the install?

sounds like you're getting "port loading"...at least i believe that's the correct term. It's quite common if your port is closer to one woofer

It shouldn't have, its spring loaded terminals on the sub and im running 12gague wire. and my connections out of the box are bolted with ring terminals on either side, i'll double check my work tho.

Is there any way to fix this? i was thinking about fitting a baffle between the port and the sub closer to the port? think this will be affective?

Hmmm... that might be an option. How far is sub from the port?

13 inches from end of port to edge of basket.. i'd like to take a picture to show you the shape of the box.. but i currently do not have my camera with me.. but its a wedge box the subs are on the front and the port is in the side

This is actually something that I'm worried about. I may just port middle.

I cannot port the middle because this is in a single cab truck with a bench seat.. but that would be the best way
