Was sending 200 watts a side to mine on my active setup until i had so much trouble with the tweeters, doubt it was because of the power and more of a manufacturer deal since they sucked form the beginning but on my new set I'm sending about 70 watts to my tweeters and 100 watts to my mids and they sound good to my hear. Keep in mind that the only other comp sets I've heard have been stock sets with the scion TC and cobalt SS and then some crazy setups at Car shows. However I still think mine sound pretty decent except for some annoying resonances at ~110hz in my frame which I won't take care of until i have enough money to spare to put some damplifier pro in my doors.a lot of people on here were throwing 200rms per side on the PG RSD's and said they sounded pretty good....
Those speakers are power hungry monsters. An employee at my local tweeter (now closed) had them running off a TXA-6004. He said they were at "full power". I dont know what that ment but to that amp im assumeing it was 600W per side.I was putting around 550 to my old Boston Z6's and they LOVED it. Probably could've given them more....
