I just bought the Shaker 500 and it came in the mail today. I hope to install it tomorrow

I was just searching through eBay and came across these:

They are a pair of Shaker 1000 Door speakers. My car does not currently have the door subs or anything. Would I be able to get these and have them installed in my doors?? Also how much would it cost to have these things installed? And last will these shaker 1000 speakers work with my shaker 500 unit? Or would I need to buy a Shaker 1000?
