If the box matches up to that driver's requirements for best performance, but not familiar with Skar particularly nor looked for t/s parameters or anything. The Stereo Integrity SQL would be what I'd go to for something newer/larger, tho, especially when spending someone else's money
. That Alpine amp looks decent. I got one of these Rockford Fosgate
amps when I had to replace driver/amp in my truck (but that amp was only $150 at the time) and used an Infinity Reference 1070 as it matched up well to the box I already had. Didn't need to update head unit or speakers, tho.
