ok, here is the install that i did on my 1997 cavalier 2door, it consists of:

Clarion DXZ-635mp

CDT-HD-62 components (HD-6, DRT-25, 560)
MB Quart RA 2400 (200watts rms x 2) for components
Orion 1200D (1200watts rms x1) for sub
RE XXX 12" D2 Sub
3.5cu foot box tuned to 28hz
100sq feet bquiet extreme
stinger interconects, and various stinger wiring 1ga and 4ga wiring


it took me about a month to get everything done, but im very happy, i just wish my xxx was a bit louder, as my HD-62's can make you ears bleed...

 

more sub box pics:

 

wow that box makes my head spin haha was it hard to tune? but nice install guy

 

Very neat box. Looks great.

 

3.5cu foot box tuned to 28hz

nice

 

haha wow 28hz, nice and low, how does it sound? thats really an impressive box, i'm glad to see a j-body car put to good use i have a 2003 sunfire i use for spl, i'll post some pics up for ya.

 

the box wasnt that hard to tune, just had my dad help me bend the tape measure around the centre of the "u" joint and i was able to get the correct length. the box sounds damn good, nice and low, shakes the whole car, i just wish i coulda fit a 15" XXX in there... however the simply wasnt enough trunk space

 

I personally wouldn't call it an SQ car, but for a daily driver it looks good. now the fun part begins... hide all the wire, put in some trim panels, and tune that bad boy up!

 

Us SQ guys are so picky....it does need alot of cleaning up,but great job!

 

What do you mean you can't fit a 15" XXX in there? They don't need a 6cu.ft. enclosure for a good sounding daily driver. 4.0-4.5net would be plenty in a ported design and that will easily fit in there.

On to what you have though; that bass end should be able to keep up to your front end just fine. If it isn't there is a problem with your design/settings.
