I'm curious, you are hooking the terminals of the subs in parallel and then hooking that connection in a bridged configuration to your amp. If I'm right you should have in one way, shape or form, BOTH positive speaker leads going to the Postive terminal of the right channel and both negative leads going to the negative terminal of the left channel, or visa-versa (depending on your amp). This would leave two empty terminals and your amp should set to bridged mode.
That covers the wiring. But here is the thing, if I understand you right. You have two subs (most likely 4 ohm coils) wired in parallel down to 2 ohms. Then you have them wired bridged to your amp, which would see that load as 1 ohm.
Since there are not too many 1 ohm stable stereo amps in that power range out there, I would say your amp just can't handle that load and that is you problem. Switch back to the stereo configuration and you'll be fine. If you want more power get a different amp, but be careful not to damage your subs in the process.

No....well i bought the box used...havent opened it up but i have 2 speaker terminals/ one for each speaker..im assuming running at 4 ohms....so when i double up the positives and negatives together/thus reducing the ohms to 2 ohms if im correct. Phoenix Gold are normally very good at 2ohm stable. Same thing happened with my kicker amp. Right now im running it straight(stereo) which I know im not getting most of the amp. Sounds ok but not getting that PUNCH when i run bridged.

You are correct, you're not going to get the most out of your amp, because you can't run a 2 ohm load bridged. When you bridge an amp it's just like running it at 2 ohms with a 4 ohm speaker. So if you connect your 2 ohm load in a bridged configuration your amp thinks it is actually 1 ohm and goes into protection.
The poor sound quality (lack of punch) is directly related to the fact that the amps power supply cannot supply the nessesary current to the output transistiors, and they 'bog down' to put it simply and eventually over heat.
Your best bet is to get a mono amp that is 2 ohm stable. You could find one for your application quite cheaply.

If you have a 2 ohm load, it is a 2 ohm load. Doesn't matter how they are wired or how many subs. 2 ohms is 2 ohms. In stereo or bridged the amp still sees the load as 2 ohm. (until music is played, then its all over the chart)"So if you connect your 2 ohm load in a bridged configuration your amp thinks it is actually 1 ohm and goes into protection." .... sorry ....YOUR WRONG...
The amp goes into protection because it can't handle the added heat caused by the added current to make the extra power when bridged. Amp still only sees a 2 ohm load. It's just not liking it much.
