two jl10w7's but what amp and how

ok i will be using two amps  the jl 1000/ for my subs  and a e6450 for my midrange speakers so how do i connect the two amps together or do i need to I know that i will need to run power wire and a the amp turn on and the ground, but now what about he amp preouts. And another question? hwo do i set my cd player settings to get the best performance out of my system i got a pioneer premiere DEH-p860mp. and i might have 5 Polkaudio mm 6510 with crossovers for sale

the amp has a preamp output, amplifer input. and a subwoofer output with 4 holes two pos and two neg what plugs into all this three things

Why do you insist on using the preouts on the amp?  How many sets of preouts does your deck have?  If you have front/rear/sub, then you'll use the front/rear outputs for your interior speakers' amp and the sub outputs for the sub amp.  If your deck only has front/rear preouts, you can use one or the other (preferably fronts) to connect to the sub amp, then you'll set the preamp outputs on the sub amp to full range and use the crossovers built into the next amp.  If your deck has a sub output and you use that, do not use the preouts on the sub amp because you might send only bass to the next amp. 

As far as the speaker outputs go, it doesn't really matter as long as you don't connect too low an impedence (below 1.5 ohms I believe) to the amp.  It's a mono amp, so both the positives are the same, and both the negatives are the same.  You can just run one positive and one negative to each sub.
