OK,
there are 2 ways of doing this.
I would advise that you use 1 amp to drive the lows (or the bottom pair of binding posts) on each speaker, and use the other amp to drive the highs.
The only problem is that I don't know if you have 2 sets of pre outs on your preamp, or just 1.
IF you have 2 sets or pre-outs, then you connect 1 set of outputs to the top amp with interconnects, then connect this amp to the top set of binding posts of each speaker with your speaker cables.
Then connect the second set of pre-outs to the bottom amp using interconnects, then connect this amp to the low binding posts of your speakers.
So, you have 1 amp driving your woofer (or mid if your speaker is a 2 way), and another amp driving the midrange and high frequency drivers (or just the tweeters if your speaker is a 2 way).
I bet that you only have 1 set of pre outs on your preamp.
IF that is the case, and there's not a set of LINE LEVEL OUTPUTS ("RCA OUTS") on your amp, then you need a splitter, basically it's a "Y" with a male rca on the bottom of the "y", and 2 female rcas on the top parts of the "Y".
SO, you plug the bottom of the "Y" into your pre-out on your preamp, then you plug 2 sets of interconnects into the 4 "top" parts of the "y"s. THen, 1 right, and one left to each amp.
THen connect the speaker cables as mentioned above.
'Once you're SURE that all cables are properly connected, then plug in the power, and juice 'em up.
IF you did it right, turning off 1 amp will leave the highs on, while the lows go off, or vice versa.
good luck.
(If there is a set of INs and OUTs on one of your amps, then you go into that amp from the preamp, then out of the outs of that amp, into the second amp, connect 1 amp to the right and left high post, and connect the other amp to the right and left low posts)
