Amp advice for Polk momo’s, 6.5''

Hello,  I am looking for an amp to power the polk momo 6 1/2" component speakers that I am going to be putting in my car ( http://www.crutchfield.com/S-uBPwGDkQomG/cgi-bin/ProdView.asp?search=polk+mmc6500&i=107MMC6500). 

I am currently running a alpine cda-9851 headunit, (have a alpine type r 12" in the back).  I was wondering if you had any amps you would like to reccomend as far as brand or model #. Im kinda shooting towards the cheaper end if possible price wise, so not looking especially for the big brands (alpine, jl, etc.), and was wondering if there were any amps in the 100-200 range that you would reccomend I use to power these speakers, however, all reccomendations are welcome.  Links would be appreciated.

thank you

That would be OK.  This would be much much better if you can stretch the budget, bridge the two rear channels for your sub -

Or look for the EA 2000, the 2-channel version, a little cheaper but no sub option.  These are great amps at a great price.
