Wow Jonathan, aprpeciate your effort in trying to help.
What I was thinking is that, at first I can get the subs installed with 2x RE RE10 with a KX 350.2 refurbished pushing it.
As I get some more money, I will get another KX 350.2 if it turns out well, and use those to push my front components whihc will probably be some CDT CL-61a.
What you guys think? Oh and Jonathan I did some research on taht 550.3 but it seems kind of shady to me. I think im still preferring to go with the 350.2.

Suit yourself, the 550.3 is a great amp for pushing a whole system, though. That's a route we went a lot when we were putting systems together for under $1000, and it worked great.
I'd still recommend getting the one better sub, and possibly a Class D mono amp. Maybe a 12" sub instead of a 10". Get one that will present a 4 ohm load to the sub, and if you want to upgrade later you can just wire another sub to the amp at 2 ohm to double the power.

Hum.. That 550.3 is kind of appealing to me.
Sorry for asking for a lot of information, but what are the exact RMS breakdwons in 4 ohm and 2 ohm?
What is your recommend sub and 6.5 component speakers for the 550.3? thanks a lot I apprecatie it greatly.

14.4V:
70 watts x 2 chan. @ 4 ohms
85 watts x 2 chan. @ 2 ohms
Sub Power:
210 watts x 1 chan. @ 4 ohms
420 watts x 1 chan. @ 2 ohms
12.5V:
40 watts x 2 chan. @ 4 ohms
70 watts x 2 chan. @ 2 ohms
Sub Power:
180 watts x 1 chan. @ 4 ohms
360 watts x 1 chan. @ 2 ohms
Thats the breakdown. Keep in mind, you're gonna wanna change your sub selection if getting this amp. Do what jon said and run a single 12.
here's a link to that amp on sonic electronix.

Edit: this sub would sound good on that amp running at 2 ohms

Would I be running it at 14.4v or 12.5v? Or can I choose? Does it matter on my car or something?

Well, 12.5 is what a batteries voltage is when just sitting there. 14.4 volts is what some cars charge at. Most cars charge between 13.6 and 14.4 volts.

Just in case you were still thinking of going refurb to save some money

I know it may seem I'm pushing these guys but I'm really not I just know they have really good prices and am trying to help you stay on a budget and free up money for a higher end front stage so just let me know if it's getting annoying. I know what it's like to be on a budget with three kids :P

It would be somewhere in-between. Most alternators will be in the mid 13s as far as voltage goes. The amp itself is underrated, you'll usually get around 70W RMS x 2 on the front channels from realistic voltage levels, same goes for the subwoofer section.

I'm probably going with a refurbished kx550.3 - Going with the math and stuff, I realized that I'll be paying like $125 extra just for the install + wires of the 2nd amp. So why not just go with 1 amp?
Just need to find a good sub for it.

Me and Ridr4lif were talking. And heres what we've got so far for the sub:
MB QUART DWF304 Dual 4 Ohm Voice coil $67 SHIPPED ON Ebay!
Diamond Audio D312D4 Dual 4 Ohm Voice coil $110 SHIPPED on Ebay!
Both are brand new. Which one would you choose or do you have another suggestion?
