Heres my rig:

JVC KDG 230 http://www.jvc.ca/en/consumer/product-detail.asp?model=KD-G230

2 x 12" MMats Procast 600 WRMS Dual 4 ohm vc in a custom 4.5 cu ft. box, port tuned to 38 or 39 hz

1 Memphis PRD 1000.1 running at 1 ohm (Subs are wired in parallel)

1 Sony XM255EX powering two panasonic 160 WRMS each ex-house speakers.

and the two front door speakers 4x7 AC Delco paper cones.

Now, I just upgraded the Amplifier, I was running the subs off 360 WRMS combined. I thought that jumping up to 1000 watts RMS would make a huge difference, but it just aint cutting it for me. I have seen vids of people running this amp, and two 10's, and they can barely keep their car doors from popping off the car. Why is it that with my head unit at 30 vol. (Max is 50 I think) The bass won't even make my remote dance on the roof.
Gains on the PRD are 1/3 or better, 0db bass boost, subsonic is at 35hz, LP filter is at 60 Hz.

if you didnt notice much of a difference then you need to spend more time tuning the amp would be my guess... because, depending on what its in that should make alot of noise...

I still have to set the gains using a dmm. I thought it would make some extreme noise too, thats why i'm baffled that it still sounds the same.

i have never been that technical with setting gains hahaha i just turn the damn thing up till its loud enough... just put on something with fairly consistent bass, then turn it up to what would be your normal listening volume then start slowly turning the amp up, till it makes enough noise, hahaha

are you sure one of the subs isn't out of phase?Cause if it was you can say good by to bass.

while you have the DMM out to do your gains (not he best way) double check that the subs are in fact showing the amp a 1Ω load and not a 4Ω one.

other than that, or above suggestions, maybe you're expectations were unrealistic?
