whats rhe size of the amplifier

Dimensions of the R4002 are 10.79" x 10.43" x 2.25".

I just purchased a BOSS Armor Series 10inch 2200 watt sub and wanted to know if this amp would push it pretty good?

For a few more bucks this is a better match for your sub(SSL EV2.2000 EVOLUTION 2,000-Watt 2-Channel MOSFET Amplifier). Now with that being said your 10" sub will not handle 2200w it will only handle very short peaks of 2200w and it would have to be clean wattage. this amp will push it well set it about 3/4 and X it over at about 90hz

Can you support two 10" subs with this one amp?

Hello. Yes, this amplifier will support two subwoofers. You will need to make sure that each subwoofer does not exceed 400 watts peak power.

will this amp power 2 6x9 500 watt door speakers and 2 rear pillar speakers?

It will with ok sound quality if it's for inside the car listening pleasures. However getting another one and bridging it or a higher powered amp for a good baseline would be recommended.
