I'm new to the forum. Been lurking for a while. Just joined today. I'm a bit of a car audio nerd. I am currently shopping around for my next system. I Just sold my old truck, and all audio equipment. Here's my new situation.

2003 chevy crew cab (can't fit ANYTHING)
I'm forced to do either a bed cut, or custom console. I'm going for the console box. I'm also a JL Audio finatic (love us, or hate us) Want to install atleast two tens in place of center console. Removing flip up console, and cushion underneath. Willing to use space from very front, all the way to back seat (forming center console in the back) Any box building vets that can help with design? can provide dimensions. Or, any advice on how to figure airspace needed. Some experience doing this... but want this one perfect.

Likely going 10w6, considering w7.

First step is to pick your woofer. This way you know how big of an enclosure to make. I assume down firing would be best in this application, since passengers will likely be all over the sides/top of the console.

Post up some dimensions too and go from there.

Ok, 2 JL Audio 10w6's.

These are the MAX dimensions. Don't HAVE to use this whole space. This is just what I have to work with.

L= 48"
W=13.25"
14" Keep in mind that it's 48" from the lower dash area, to the back seat. I'd prefer the box not to be 14" tall all the way to the front ( due to asthetic reasons) . I'm pretty good at woodworking (built cabinets for a few years) so I'm up for antyhing.

When I get some free time I'll see if I can work on a design. Do you want a stepped down center console going all the way to the front? Or would you prefer to just cut it short and not go all the way to the lower dash.

step down would be awesome so i can keep somewhat factory look. Your help is highly appreciated.

I would place both subs on the bottom of the enclosure and do a down firing setup.

Not sure if that design would have any cancellation issues or not, having the subs directly across from eachother. (Still learning on the box/acoustics aspect)

No, there's no cancellation with opposing sidefiring. But it does help reduce vibration.

Here's a downfiring version though.

that is a very good design...and if executed properly would make one hell of an enclosure...maybe throw some FG in there to make some of the transistions smoother.

would putting a plexiglass window on the top of this have any negative effects?

there's only one problem I have with this version. The mounting depth on the 10w6v2 is 6.9"... wouldn't quite work, would it? too early for me to do the math.

Plexiglas should be fine as long as it is very thick and sturdy so it has minimal flex.

Some notes of the box: I would try using some poly-fill or acousta-stuff inside. The downfiring box is about 2.63 cubes net before driver displacement. Stuffing will make the subs "think" the box is bigger, which will lower the Q and they should hit a little lower.

Also the box is quite long so you may want some minor horizontal and vertical cross bracing as you feel appropriate to keep the sides and top rigid.

Yeah the mounting depth might be a problem for side firing.

I think the downfiring enclosure with plexi side windows would look cool, especially if you wired some LEDs inside. Then maybe put some cupholders on top or something. :)

yeah, I'm thinkin either side or top window. could always put cup holders on the front where it's tapered down. hopefully my drinks will need a good lid :D haven't had this small of a setup in a long time. Hope it hits hard enough.
