Subwoofer cut out hole in the right place?

It's impossible to trouble shoot this thing with out looking at it. For all we know he could have a low pass set too low and blocking out most of the frequencies you can hear. Infrasonic filter could be set too high but not likely. How are gains set? There are just too many variables. The best thing would be find a friend that knows what they are doing and have them look at it. How are the ports tuned? If you screwed up making the box, the output would ****!

Low pass is set at around 100hz. Subsonic at 25ishhz. Gains are set using a DMM, at 37.4V(700watts@2ohm). The box is slot ported to 32hz.

The high pass on the deck could be cutting off low frequencies. Turn off all eq features on the deck. Which amp is powering the sub? Is it a mono block or a 2 channel? If its not mono, how many watts are you really drawing? You might think your pushing 700 watts rms, but you may be pushing far less. Put the sub in a friends car and hook it up to their amp. You can then rule out if its the sub/box or amp/deck and go from there!

All gains have been set with all eq's off, HPF on deck is off. The amp is a Kicker Ex1000.1, mono.

So ive moved everything around, so the sub now has more clearance from any wall.

The clearance from the parcel shelf when down -

When im listening to a bass heavy song on my max undestorted vol, the shelf barely moves.

I might have to build a new box, for some reason i think it might be too big.

amps-

Did you ever recheck the wiring in the box? If they're hooked up backwards it'll still show the correct ohms on a dmm.

Have you tried switching + and - ?

No i didnt but i will tommorow if i have the time. and no i havent tried switching, but isnt that the same as phase? if so ive tried both phase settings on the deck and on the amp and that hasnt really helped.
