hey guys, i finally decided to throw an amp and subs into the expy. what direction have you all found to point them that sounds best? back, up, angled, downfire? im going to build a box this weekend and just looking for a cheat on the best direction without the trial and error. i bought 2 12" polks and a boss amp. they call for .88 cubic feet and a sealed box. thanks, dan

The downfire thought for putting stuff on it was what I was thinking. How much space is under the box? Also are the subs screwed in from the outside of the box or mounted from the inside? Just thinking its a lot of weight constantly pushing on the screws.

Downfacing I would suggest a double ring face with bolts/ t nuts to keep it happy :)

If you want to achieve the loudest sound, subs back and port back.

The subs say sealed @ .88 cubic feet so ill prob do that. Just a toss up between facing back or the downfire. Im a firefighter so I carry a bunch of stuff in the back and the protection of the downfire is a plus.

mines on the driver side. facing passenger with port in same direction. custom box. 2cbft. its a good size box. haha but down fire is your best bet. you can throw stuff on it and no worrys. and even better is to add a little bit of cross support inside the box to brace it so you can really throw stuff on it and have no worrys.

Try facing your subs back. When you want to haul anything you can always just flip the box so the subs face up and you have plenty of room to haul stuff and not have to worry about anything touching the subs. That`s what I do. I can fit a dryer in the back of my truck with the subs facing up and have plenty of room left for other stuff.

When I had my 2 18's I had subs up port back. It sounded great but is louder with subs and port facing back. If your planning on being loud with subs facing up do sound mind of sound deadenjng on the roof. Its loud when it flexes and slaps against the braces.

The better the sub can breath in an enclosure that's been properly calculated for port size, and the more distance the bass has to propagate the wave uninterrupted (vehicle), the better it will sound.

The ported enclosure is the first box, your vehicle is the second box. Try cramming too much punch in to too little space and you defeat what you're trying to accomplish. Plus your rig just rattles like some cheap hoopty vehicle.

Depending on what you're after tuning in both an EQ and amp may be required. You can say something like "oh but bass isn't directional" but if the wave can't propagate at least a good % of the actual wave length, it's going to sound like distorted PUNCH, not smooth authoritative bass you want with William Orbit, Paul Oakenfold etc. U2's Rattle and Hum ends up just being rattle and rattle.
