amp in stereo and bridged

i have a 780 watt Pioneer amp, 2channel. Running two 10 inch dvc in paralell. I also have a 12 inch svc bridged on the same amp. The two tens combined draw a two ohm load. Would bridging the 12 inch bring the load to 1 ohm on the amp???

      {Thanx in advance}

ok thanks for the reply.  the pioneer amp is gm-x962. pretty straight forward amp. that is pushing 2 audiobahn 10's ,dvc. they're hooked up in stereo and the coils are in parallel.  I also have a polk gnx12 with a seperate 1000 watt 5 channel running the 12 , 6x9's , and 6.5's. the extra 12 bridged from the pioneer was kinda absurdly unnecessary , but curiosity overwhelmed me! it didnt sound too bad either . but I needed  to know , for sure, that the wiring setup was or wasnt going to burn up my amp.    So I  take that as a no go , huh??

   p.s.   what did you mean by cancellation , on overpowers the other and you dont hear specific tones or ? I'll try and look it up in another post though  .but info is alweays appreciated   , thanks alot!
