Technically since low end bass is not directional up-fire vs. down-fire (or rear-fire vs. front-fire) should make no difference in overall sound quality.

I personally like down-fire enclosures because it keeps the cone out of harms way better.

as long as you keep junk from getting down there. speaker grilles can offer protection no matter which direction you fire the sub.

Downfire or firing the sub away from you will reduce some of the rattling, chatter-ish noise you hear when a subwoofer is hitting, usually at higher volumes. It may make the sub sound more dull with less range, but can clean up the sound a bit.

Have you ever cranked up the volume and put your ear next to the sub? You can hear rattles, distortion and other noises coming from the sub itself. This is not noticeable if you are sitting far away from your sub (ie: sub in the back of an SUV), but if you have the sub facing you in a small cabin 2ft away from your ears (ie: a king cab truck), it will be easier to hear these sounds. Firing the sub upwards or out into the cabin tends to move more cabin air and may feel like a stronger hit/pound...it can also make the bass more crisp sounding....but again, you may hear the unpleasant sounds that the sub is producing.

My suggestion is to just get a basic box that fits, and move it around in the cabin, facing it in different directions until you get the sound you want. I've tried out 3 different box set-ups for my current sub, in every possible direction in the back of my king cab truck ported/vented and sealed. I probably went through 3 or 4 different boxes for my previous subs that I had in this truck. Every sub/box combo will sound slightly different. Also, ported vs. sealed can make a huge difference in sound. For example, when my sub was in a sealed box, I prefer it facing the back of the seat....in the ported box, I prefer it facing out into the open/upwards because it soundsfeels much more powerful when its moving all that air.

Have you ever cranked up the volume and put your ear a foot away from the sub? You can hear rattles, distortion and other noises coming from the sub itself. This is not noticeable if you are sitting far away from your sub (ie: sub in the back of an SUV), but if you have the sub facing you in a small cabin 2ft away from your ears (ie: a king cab truck), it will be easier to hear these sounds.

Then there is the whole debate between ported and sealed.
well since my 07 is a cc i dont have much room so its just a down fire or up fire under the seat. i just want a good clean crisp bass sound with the subs.

By putting it under the seat, it wont make too much of a difference. It will already be muffling the sound to some degree. I'd probably fire it down.

Well, I have to disagree here.
You can not "muffle" sound that is not directional in the first place such as low end bass unless you are impeding the cone excursion.
Ported, I'd go along with the idea of the port being compromised by blocking it's output pressure.
A sealed enclosure not so much.

That being said, when my truck is sealed, all windows up and the sunroof closed, the bass sounds quite a bit different than if one/all of those is/are open.

Now, block the mids or highs and I'd go along with the statement of "muffling" sound.
