Generally speaking, clipping/over-driving a low-power amplifier is a much larger issue than a high wattage amp will be. So I don't suspect you're going to run into issues unless you somehow manage to blast everything at max volume.
The tweeter is the BG Neo3 PDRW w/deep back cup, which are no longer available.
The GR Neo3 is a custom design intended for open baffle use and are not a drop-in replacement, unfortunately.
The I believe woofers are a slightly tweaked version of M130, but Should close enough to be a drop in replacement.
Unless you're regularly listening at concert to reference levels, (105-115dB) in a large room several meters away from the speakers I doubt you'll ever run into any issues.
But if you want to be safe, and assuming you're using a separate preamp, it wouldn't hurt to had a high-pass filter to your power amps rolling off around 40-45Hz range which will help to protect your speaker from seeing tons of power down low.
