2x RE12's at $76 a piece....
1x Hifonics BX500D at $189.95 and thats with shipping.
These subs recommend 1cuft of airspace.
That would be 250 watts a sub. With your setup right now you are showing your sony amp a 2ohm load which make it 400watts. Thats 200watts a sub. I would really suggest turning down the gain on your amp. That might help the bass out a little bit or at least it wouldn't be killing your subs. Here is a webpage that I found in these forums by searching for info.

If you want to see these subs in action go to www.realmofexcursion.com and click on videos then scroll down on the left to RE Audio and click it. It will brings up videos fo their subs so scroll down a little bit and it will have videos of these subs except only the 10 or 8" versions.
All together it looks like $350-360 for two 12's and an amp to push them. You can buy direct from RE Audio by calling (702)896-4823.

wait...I thought I was running 1 ohm at 400 watts per sub. I have them bridged to the mono channel 800 watt amp. Am I mistaken?

I have 3 controls on my amp LPF, Low Boost, and LEVEL

I am assuming that LEVEL is the Gain because its measurements are .3 .1 0 2 4 6. I have/had this set at .3

More bass = more displacement, more power, or both.

Ported enclosures are usually louder.
More efficient drivers are louder given the same amount of power.

Apply the above as budget allows, repeat.  You'll have more bass.  :-)

This means that your amplifier will output its maximum when the input reaches approximately 0.3 volts.  Above that and your amplifier will clip.  Depending on what head unit you have this means you are clipping the amp (and destroying the speakers and sounding like crap) at any head unit volume level above 1.

Set your LPF (low pass filter) at about 100Hz.  Set the Low Boost to zero or off.  Set your level or gain properly by matching it to your head unit's output levels.  If you do not know how to do this, please do a search on this forum for instructions, or go to http://www.bcae1.com/gaincon2.htm and see if you understand, or get help from a pro in your area.  Otherwise, no matter what subs and amps you buy you will simply destroy them and they will sound like flabby ass.

From what I understand, your amp is a mono amp. Your subs are 4ohms each. Run them in parallel and that would present your amp with a 2ohm load. Somebody correct me if I'm wrong.

Ok..heres what I did. I set my LPF to 100Hz, Low Boost to 0 and LEVEL to 5 because my deck says its 5.0V preamp out. When I max the volume...very minute bass. This kinda took away all of my bass instead of eq to the correct setting.
