I have four MA-500 monoblock amps that I using to power four 12" Crystal Audio & Video drivers. They drivers are rated 4ohm and up to 400W, but the amp they came with was a 200W RMS. The monoblocks I drive them are 180W into a 4 ohm load. This might be a silly question but do I loose or gain anything by running two of the 12" drivers with two bridged monoblocks? If I could do so I could use the speaker plates in my HT and try and run the amps in my equipment closet which would get my amps off my front stage.
Here are specs for the amp. Also let me know if you think I need to bridge each one, get a new amp or amps etc? I can't do so right now but might in the future.

I could place each sub next to my left, right, and left, right surrounds to get a flat reponse also, but the output for the the lower frequencies on the ones at the surrounds would be low and there would be a loss of 2dB.
I used to know the answer to this and I think last time I asked about this question for my 15" subs that were clicking on off the amps protection and the answer was that my amps were not powerful enough to handle the 2 ohm load. I tried running some sweeps and they do work bridged, but this does not mean for certain it will work for movies I think.
Also can you tell me anything positive or negative about this driver by looking at the photo? I don't know the full specs and not sure the manufactor could reveal them. It is said to have 18Hz in-room. Does it look like it is lacking in a certain way and if so why? This could possilby help prevent me from trying to get to much from them. They do not bottom out the way I currently have them set and I have never been able to do so. The room is near 2300 cubic feet. Thanks.
