Does it make a difference what shape your subwoofer box is in, as long as it
has the appropriate volume of air/space? To limit the amount of space taken
up in my trunk, i'm looking to go from 2-12's to 1 and would like to custom
build a box that is the width and height of my trunk, but only as deep as it
needs to be. Does this make sense?

Side note: how much bass will i lose going from 2-12's to 1? I'm running an
old old alpine v12, 2 channel.

Can anyone give me details on how to hook my amp up to the one sub? I
believe now it is bridged to both subs. It's just been so long since i was
into this stuff. Maybe you could point me in the direction of a website
that will tell me the best way to hook the amp up?

Thanks. Sorry for the stupid questions.

Bass frequencies are long compared to the size of a car so you don't
have to worry about standing waves. The box just has to handle the
stress. A wide and shallow box will need a lot of cross bracing to keep
the frequency response smooth. Large top and bottom panels can move a
lot of air with just a little vibration. Hardwood or even metal would
save you the most trunk space. Particle board will have to be pretty
thick.

Whether or not the 1 speaker box looses bass depends on the tuning. You
might loose nothing if the new box is tuned better than the old one.
You could loose it all if it's tuned worse. I built some extremely
quiet subwoofers when I was a kid and not using speaker enclosure
calculators.

I don't know about the wiring without more info.
