Using 2 different model amps to drive one pair of patio speakers....novice questions


I am running a pair of JBL 28T speakers on the patioI have two amps acquired over the years
B&K ST2140
R Fosgate RF2000 (Bridgeable .....whatever that means)

Can I drive the pair with different amps pushing 1 speaker each or
Can I bridge them and then connect the 2 speakers to one amp and get a piggy back effect of more power

I am clearly no sound technician Thanks in advance for any help and comments
I want to use what I have acquired over the years but don't want to do something stupid

Do your speakers have two separate pair of binding posts on the back?  If yes, and they currently have a jumper connecting the two together you have a chance to experiment.  Remove the jumper connectors on both speakers.  Now you can perform Bi-Amping.  You will need two pair of speaker cables, same length, same make.  Hook amp 'A' leads (L & R) to the top binding posts.  Hook amp 'B' leads to the bottom posts.  Four hook ups per speaker, eight total, from two separate amps.  Now your in business.  The sound may not be what you are expecting.  You may need to run different volume settings on each amp to smooth/steady out the sound.  For Bi-Amping to work properly the amps must have closely matched electronic signatures.  But, what the heck, its worth a try!  Years ago I Bi-Amped a set of Kef Reference speakers with a C-J Premier 11a tube amp and C-J MF2250 solid state amp.  A single C-J Premier 17ls tube preamp ran both amps.....  It worked as an experiment.  
No
One set of terminals on each speaker.
I am fine with my plan. I do however have to sets of terminals on the back of my Polk RtiA3 speakers. I have them on a Carver M500 amp and an old Kenwood KA 7300 integrated I use as a preA
