so i took my box out of my car to add some fiberglass resin to it, and some supports, but i was wondering what side should a port be on for the best spl. passenger side or drivers side. the sub and port will be facing the trunk.

Thanks,

Only way to know is to test it out for yourself.

Generally you load the mic side with the sub. Meaning since they generally put the mic on the passenger side, you want the port to be on the driver's side.

i have found that porting on one side of the box will cause the further sub to fight to breath and the closer sub to the port will bottom out first.

I port in the middle, I think it looks better and the port acts as bracing.

Port on the rigth works good for most cars but you will need to test because no 2 cars will be the same.

Mine is on drivers side, gets pretty loud. Havent tested the other way, though. Really only way to tell is to test, like bromo said.

"Common wisdom" is to put the port and sub on opposite sides, but to be honest when I did it in the hatch eons ago both in the middle worked beautifully.

Thor runs his port on drivers side as do i, from trunk cars with forward firing boxes sealed from the boot this seems to be the loudest setup

I guess the only real way to tell is flip the box and test and see which is louder on the meter

Edit: If its the car in your sig then sub up port back for sure, if you can or dont want to run sub up then i would run the port on the drivers side, but like i said subs forward/up would be much better and meter louder too

i dont agree with the sub up port back thing, just because my car is NOT a hatchback. its a chevy cavalier with a trunk.

and i didnt do any testing on this i just kept it the way it is, sub and port facing back with the port on drivers side. i didnt do any testing because the box is just too difficult to get in and out of the trunk.
