Great, thanks for all the suggestions guys. Here's my take on things.

I currently have an amp to drive my 2 12 inch subs in the trunk. I will be either splitting the rear empeg output to the rear speakers and rear subs. Now if I do happen to find an amplifier with 4 channels with a front/rear adjustment I just might split front output to the front and rear speakers driving the subs only with the rear outputs.

I am glad to know the empeg is potent enough to split the outputs to multiple amps, great stuff guys!

About the bridging... well the current setup isn't going to be really efficient for my del Sol, so I may consider trading up to a single (RF, or something like that instead of Phoenix) sub and using my Craig amp to drive it. I asked about the bridging because it states on the amp that it is bridgeable but unfoutunately I bought the amp used (from a Car Stereo store, and theft isn't a big business here in Newfoundland, Canada) and it never came with a manual.
So now I can bridge her.

Again thanks for all the help folks!

(Now if only June 9th would hurry up and get here! )
