Exclamation help with wiring my Amp for best power?

Hi all,
I am still very much a Car stereo Noob. So please bear with me with my Easy for you to answer Questions.
So I am going to be wiring up my Car stereo on friday so I am still getting ideas and feed back as to the best way to wire up this puppy.
I have:
Kenwood KAC-8104D Class D Amp 1000 Watt Peak

http://www.crutchfield.com/S-EVj5yJL4Irw/App/Product/Item/Main.aspx?i=113KAC8104

Two Clarion 10 inch subs #SRW1051, 750 Watt peak (375 RMS)

http://www.sportcompactonly.com/Hummer/Clarion/Subwoofers/Audio-Video/part_c-261_b-414_p-160447_m-38.htm

Sony Explode Head unit #CDX-GT52W 52 Watt*4

SCOSCHW 1100 RMS High Power Amp and Digital stiffening Capacitor Kit #KPCA4F)

The door speakers I am picking up on Friday (Payday), Won't be anything special, My budget is under a 100 Bucks for a pair of somethings (advice on a set of something would be great)as I blew too much on the rest of my System off the bat. Pretty much a small starter Stereo for now. Planning on addig a Single High Power 12 Inch to bring in some more Low end thump when i get more cash.

But anyway, This Amp is a little confusing for me to wire. I read that you need to wire it in series or something to get the most power out of it?
I got it brand new but it came without box or Instructions.
Can someone please explain to me how to wire the Subs off this Amp?
My brother is going to help me with the Actual wiring of the Power wires from Battery, But he also has no Idea how to wire the subs. We always thought you needed a two channel amp to wire two subs
My friend has a Alpine amp that when you run one sub it has only 300 Watts RMS, But wire up another sub and all of a sudden the Amp can produce another 200 Watts RMS for a total of 500 Watts RMS or something like that.
I have been trying to read up on this stuff online but I need someone to break it down in Laymans terms for me.
So is there someone out there who can help me? I really want to get this right the first time. And I want every last RMS Watt to help kick these !0 Inch subs
I have everything I need to wire this stuff up, Including 20 Feet of #12 Stranded Wire for the subs from amp.
Any othere Stuff i should pick up before I go ajead and start wiring please fill me in. Thanx to all who help out a 34 year old who can't install his own Stereo

Btw, Here is a Quoate from another Forum about a guy with Same Kenwood KAC 8104D amp talking about his 'Issue'

"Pat From Flint, MI
I currently have this amp running one kenwood 12 450 rms sub in the trunk of my car. Right now im only getting 300 rms outta this amp cuz my sub is only a 4 ohm, but once i get another then ill be getting 250 rms in each sub vs. 300 in one. it bumps like crazy. but i have it hooked up to some cheap wires, plan to get 4 gage power cables, also 8 gage speaker wires then it will really pound."

So I can run Two 10 inch subs off this Amp without killing the Amp right?!?

You will want to wire your subs in parallel. This will present a 2 ohm load to your amplifier to get 500 watts.

This is a link to a wiring diagram:

What kind of a box are you putting these subs in?

I am putting my two Clarion 10 inch subs in a 'Bassworx' Ported Box. The subs will be side by side.
Tell me If I have this wiring down.
So basically, I take the the two wires coming from the Amp, Twist the two postitive wires together, do the same to the Negative wires. Then put the two positve wires to #1 Sub positive terminal. Then put the two negative wires to the negative terminal on #1 Sub. Then take another wire and run it from #1 Sub terminals to #2 Sub terminals. Keep the Positive wires to the positve terminals and the negative wire to the negative terminals?
If I have this wrong, Can someone please tell the rigth way. I really can't afford to have this Amp goin Snap Crackle Pop, It needs to be going 'Thumpity thump Bawump Bump!!
Thanx

You should be able to wire a set of positive and negative leads to each sub. Your amp should be wired internally to see a 2 ohm load. So just run a positive and negative wire from the amp to one sub, and run the other positive and negative from the amp to the other sub.

Run a positive wire from the positive terminal of both your subs and connect them together with a positive wire from the positive terminal on the amp. Do the same with the negative side and you are done.

This link has a great diagram:
