making box, and amp hook up?

Hello, I have a few simple questions. The first is that Im going to make a simple sub box for my two 10" Kicker cvr. I read that you need to separate the two subs in the box. like this. the dotted lines is wood in the box. Also I have a 1200watt Orion HCCA-D1200. But Im not sure how to hook up my two kicker cvrs. I think they are dual 4ohm 400watts. Would I just wire them to the two speaker + and -? or do I hook them up parallel/parallel to 1ohm? like in the sub wire diagram.

Where on the amp do I put the wired down + and -? Since the amp said its not bridgeable. Do I just put it on any side (left or right)?

Oh ok, I will just go with the one sub to one terminal. thanks man, your always helping me. haha

Oh I never got a answer to my first question. I totally forgot. So when making a box for two 10" subs, do I need to put a wall inbetween the two?

Ok I read you dont NEED one just if one sub blows then there might be too much air in the box for it. So looking around what is a good number of volume for 2 10" box? I could only find for 1 10" box.

The make and model of the woofer has a lot to do with determining the box volume.Let's Go Brandon Brown. Congratulations on your first Xfinity Series Win. LGBFJB

Ok I got the box all up. Now I have a Alpine IVA-W205 double din. and in the back there are 3 sets of RED / white RCA ports (not including my 2 sets of AUX ports) One set is marked "R" the other "L" and the other "SW" Can I use anyone to hook up my amp?

They should be labeled F for Front   R for Rear and SW for your subwoofer amp.Let's Go Brandon Brown. Congratulations on your first Xfinity Series Win. LGBFJB
