Help with amp/speaker set up!
 

I have Aline SPX-13PRO's (5 1/4) in front dash (TW's on A-Pillar) w/JL 300/2. Two forward-firing sealed JL 6W0's under front seat's 1L+1R w/Eclipse EA3422 (bridged). Boston NX-57 (mid-rear, maybe!). Two rear-firing sealed JL 12W0's w/JL E1200. I need help with configuring x-overs! Especially my 6W0's (mid-base)! Also, can I connect my NX-57's (50W RMS), and my 6W0's (75W RMS) to the same terminals on my "bridged" amp (140W RMS), or should I take them out of the picture all together? If so,what if any are the draw-backs to doing this? I don't want to take away from my "front-stage", just add some rear fill-in! My system is set up as 3-way (High-Mid-Low)! Please help!!

Thanks:
