Amp and Sub Wiring Question

What are the last (2) specs listed?

250W x 2 (4 Ohm)

760W x 1 (4 Ohm)

are these for a 14.4 voltage source?

you have a two channel amp and two subs. you will take one sub and hook up the + and  - from that sub to the  + and - to one channel on the amp, then take the other sub and hook it up the same way.

Thanks but what I meant was by doing the above I will be running in stereo, and to my knowledge the subs wont be very productive unless their in Mono.  So how do I run 2 subs on their own channel with a 2 channel amp and get a mono signal to them?

with the sub and amp combo you have the only way to run then in mono would be to wire them to an 8 ohm load and bridge the amp. this would give the subs about 95 watts RMS. this is why i recommended wiring each sub to its own channel. if you want to run it mono, i would suggest another amp. i would look into the JBL BP600.1.
