Which way to face sub/box/port in Jeep?

[jeeper2269 10+ year member]

I have been told multiple different ways to face the sub and port in a Jeep.

the previous set up has the sub facing upward and port firing into the wall (interior wheel well in the rear cargo area)

others have said the sub should face to the rear of the vehicle (toward the tailgate)

it is placed behind the rear seat, passenger side, up against the back of the seat.

I've had good luck with this in my Grand Cherokees and seen good results by other guys in regular Cherokee. I've done well with subs and port up also. I have not had great results firing subs and port to the rear. All that said, provided you don't aim things forward the difference should be inaudible anyway provided your fundamentals are sound and if you're chasing 10ths you'll still probably want to test every variation to be sure.

Is this a wrangler, if so, go for subs either downfiring or forward. If you face them up and take the top off you are just playing out into the open, lots of bass loss.

Try them all out and whatever you want to see which is best for YOU, not for others

Yeah which specific jeep it is really makes a difference here.

Wrangler

All down firing, I've seen work well, even with ported. Sub facing rear or side, with port facing side I've seen work as well.

The problem with wranglers is cabin pressure and how that affects internal woofer loading (in the box). You really want to corner the port, get the port close to as many walls as possible.

thar makes sense. So, maybe the corner of the back seat and rear passenger wall (wheel well)

I typically wouldn't consider a seat to be equivalent to a wall, but if that's what your forced to do, then yeah, just do the best you can with it.

Local friend had his 2 15's in a Wrangler in a sub up/front ported box with the port close to the floor. It works rather well surprisingly. Soft top and all its well over 140db and can be heard and felt at a good distance. It's tearing that poor jeep apart.

Its been changed up a bit now with some legit power on B2 subs. Idk if he changed the enclosure yet but the gains can be heard and felt everytime he drives past. That jeep does rather well for a soft top even with the top off.

That's a cool place for those amps, if that's where they were.

wow!! 140 dB with a soft top. That’s crazy. I will post a pic of the current enclosure, with dimensions ASAP.
The FI I have was previously in a much larger ported enclosure, in the trunk of my Lexus IS and it was a lot louder. Just saving up now.
