Trying to find an amp to power 4 Pioneer TS-W2502D4 Champion Pros, I have a really good idea of what I need.. but I can't decide because i'm still an audio noob. I have 3 in mind, but I know there is others out there that I could use, just let me know what you think please.

The ones I have in mind are as follows : JBL GTO24001
Kicker zx2500.1 (10zx model)
Powerbass Xa 4000d
I was planning to wire them to 2 ohms.

What would be my options as far as amp variety if I wired them to 1? If I even can.

Thanks.
