amp, sub set up

i've got a kenwood 9102d mono amp with 850 watts RMS @ 2 ohms. and i have 2 ten inch audiobahn flame excursion subs, both 4 ohm, they're RMS rating is 450 apiece in a ported box. i know the correct wiring diagram would look like this... but the amp has 4 speaker outputs, labeled ++--, my question is, do i just use one speaker wire only connecting it to one set of the outputs, or do i use two wires connected to both speaker outputs and have the wiring diagram look something like this... someone please let me know, thanks alot!!

the amp is internally bridged. they just give you the other set of terminals to aid in wiring.just one set of wires connected to both subs and one terminal will be good

do u think it matters if a particular + terminal goes with a particular - terminal, or just any + and any -?

doesn't matter...theres just two sets for ease of wiring multiple woofers

cool, thanks a lot guys!
