    So far it sounds overwhelmingly unanimous to point it down.

    Does not sound like anyone has had a major issue with vibration noise in pointing it down.

    No problems at all....I am extremely happy with the downfire and its performance. Here is a link that contains a ton of information about one type of downfire box and has some really good pics. This particular company makes a box for both one and two woofers (in case you're still on the fence about how many). For space reasons, I have the one woofer box with a 10". It hits great and still leaves me a decent amount of room.

    Hi, Mfleetwood:

    Thank you for that link. I looked up what they sell for my truck.

    The issue with that box is that I am installing a Kicker S10C Solobaric subwoofer (probably from around 2000-01) that requires a box volume of not more than 0.66 cu. ft. and that box is 0.86 cu. ft. If I power it with one of my U.S. made Orion HCCA 250 (G2) amps or another higher power amplifier, they recommend reducing the volume further. I have a custom designed box for an 8 inch Solobaric that has been in the truck and has worked real well over the years. I may or may not install that one on the other side.

    I think I will have to design and build my own box. I would rather just buy one to save time, but I don't want to have to try to modify what they made to get the correct volume. I may as well build one myself.

    They don't seem terribly difficult to build, especially if you have some pics to use for guidance as to the shape, port size, location(s) etc. That's pretty cool you know your speaker specs....many just install and go. I'm definitely looking forward to "hearing" how it turns out.

    Building is simple. Carpeting throws people off but there are plenty of tricks to do that correctly, remember to use wood glue and air nail the box together, much stronger then screws because MDF will fall apart with screws.

ID:	36464This is picture of part of my current setup, im competing in MECA comps as well as IASCA comps with this setup, this is taken without the suede trim plates i made for the back wall (basically everything is exposed without this trimout), the upfiring sounds very nice but is more suscebtible to physical damage. I personally have never noticed a sound difference but all of our ears work much different so my experience is my own.
