William, the PDX line is typically under rated and even at their ratings should do a good job on those among other amps I have a JBL PS 600.4 which when I upgrade to Wet Sounds will be powering mine. It would be 123.5 watts to the Pro 80's and 358 watts bridged to the 485.
John, the Alpine PDX 2.150 should do the job well and can be had on Ebay for $250ish. There are actually lots of good options for you i.e. JL Audio 300/2, JBL PS600.2, Kicker ZX550.2
