Trunk Compartment Subwoofer, C5
I was about to reply to a thread showing a sub installed in the trunk compartment of a C5, saying that there just isn't enough volume of air there for proper bass development. I used to build sub boxes, and yada yada, from my experience I would conclude that the trunk compartment doesn't have enough sealed air volume to get the kind of bass than any 10" sub or greater needs, maybe even an 8" but that may be marginal.
So basically, what is the general user experience of using that compartment for subwoofer operation? I'd like to put a hard grill covered by a soft grill there and should be good for a 6"-8" I suppose.
Convince me that you're really getting the true deep bass that the woofer is designed for, using this small compartment size?

I haven't heard those in operation. Call me old school but it wasn't until the 21st century or very late 1990's that subs came out that claimed to require less volume behind the drivers.
I would like to hear a real high-quality real bass reproducing subwoofer that actually uses 1/2 what physics and long-time acoustics has always required: 1-1.5 ft^3 for a 10" driver. I remember when the Sub Tubes came out, the Bazooka's, yeah they delivered bass, but the punks just want bass and don't even know the quality they deliver. BOOM BOOM BOOM goes Tupac.
And of course the compartment has to be sealed. So we glue in the compartment for the sub? How is it kept air-tight? Are we lining the whole thing with dampening material because of the Fiberglass backing?
And finally, should we really be talking about 8" drivers here?

The compartment would have to be seriously reinforced. Putting damping material on the fiberglass and then just sitting a baffle with sub in would not be a good idea. Most people just build an MDF box inside.
Hopefully Spkrboy will be along soon to explain modern subwoofer dynamics better than the rest of us can.
And yes, we're talking about the compartment. Roughly 1 cubic foot with an MDF "flush" box inside. Enough for the right 12, more than enough for pretty much any modern 10 (1 is around the ported size.)

Well that's my guesstimate until I actually install it. I'm trying to narrow down the woofer size at this point.

I just measured. It's 26" by 19" by 8"deepest after the angle ends. Why try to stuff that amount of driver into such a tiny enclosure? I think you're failing to account for the amount of woofer that is flush mounted, inside the compartment. for the 10's, you're getting much less than half a cubic foot per driver.

For the 10s, you would want a "flush" mount. The pic above is a "stealth box" which has less enclosure space. In any case, the bottom half can be made from corrugated fiberglass which should give you plenty of strength, be light, and give you more airspace. This is my plan when I go back to a single 12.
