Bridging Help...!!!

Alright.. my amp is able to be bridged, but it's stable at 4ohms, but the problem is, I have 2 GNX124 Subwoofers, which are rated at 4ohms. My amp is a OV2-520 Gothic Series Power Acoustik Amp which the specs are: 150x2=4ohms 175x2=2ohms 300x1=4ohms(mono) 520 bridged. Since when you wire speakers in parallel, it reduces the load the amplifier sees. I have them wired in parallel now, to one channel. The amplifier is 2ohm stable, so it plays it, without a problem. I was wondering, since when you run subwoofers in series, it increases the load, if I ran the two 4ohm subwoofers in series, and then mono bridged it, would the amplifier see the 4 ohm load its capable of seeing when bridged mono, or will it still see the 8ohms? Since it is going over the two channels combined. Or, if I couldn't run it in series, could I run it in a combination of Series/Parallel? If anybody knows where a diagram of this or something to help me out is, I'd appreciate it if ya let me know, thanks. If someone could help me out, I'd really appreciate it, thanks again.

oh, my amp is also stable at 2ohms (stereo)

I know that it reduces the load and makes the amp push harder. What I'm tryina figure out, is since when u do it in parallel, the amp 'sees' the 2ohm load, instead of the 4ohm load, if u wire it in series, and get an 8ohm load, will the amp see it when it's bridged as a 4ohm load, or an ohm load. The site helped some though. The dual 4ohm voice coil subwoofer diagram helped me out a little, it is just like having two 4ohm subwoofers. If you wire them in parallel, you get a 4 ohm mono load, but the amp sees it as 2ohm. If you wire it in series, you get an 8 ohm load, n' the amp sees it as 4.
