Whats the loudest box i can build for my car (chevy cavalier).. i was thinkin the loudest would be subs in backseat, subs up, port back. or maybe just in the trunk facing back? anyone kno a design i should go with for two 12's or two 15's

what kinda of back seat encl sure makes the car not vibrate as much but makes more of an earthquake blocks away

Probably like an eleventeenth order sealed bandpass.

if this was so don't u think we all will be doing it? not to sound like a A hole or anything but any kind of low bass makes the car vibrates even your factory speakers if u turn it up loud enough.
now to fix your vibration problem, gut your car get some dynamat or some sound deadner cover your car from firewall back to your tail lights including doors, and maybe jussst maybe u won't have the vibration problem.....know it will stop some rattling or u will have one hellaious sound proof car. good luck and hope u get that box

subs up port back may be your best option

i have found, in my cav with a trunk box and back seat down, that sub and port forward is the loudest. tune at 38hz and peak at about 43ish ;).

sound deadening is your friend. use it! foam padding inside the trunk panels and 1/4's too. my cav didn't rattle at all...and you can't hear anything outside the car with the windows and doors closed, but you can hear it a block or two away really low and smooth.

Thats the loudest box I ever had in my old cavy. its for two tens though, two twelves are too high.

You can't possibly be serious. You haven't given us any driver information at all, and a single 12 can easily be louder than 2 if they don't have a proper enclosure due to space restrictions.
