need amps for XS-650 and XS-10FA

Ok, so I got 2 pair of XS-650's and a XS-10FA to go in my boat. (1982 Ski Nautique 2001) Now, I need an amp to run them. I am looking for whatever will sound the best.

budget is a factor though, or else I would have a better boat, lol.

Watch sonicelectronix, woofersetc, and ebay. You will find a good deal if you keep your eyes open. I bought a Orion 4800 for the 4 polks inside, and the Orion HCCA 600 for the XS-10. Waiting for the last part of the system right now, so I can't tell you how they sound. Sure look good though.

if those are sellers on ebay, they aren't selling anything currently, i'll keep my eyes open though. I've been looking on ebay, but I just don't know exactly what I am looking for.
