i have my RSD's running active, being powered by a DD S4. the S4 does 100x2 for the tweeters ad 200x2 for the mids. so far they like it. the mids didn't have a problem being powered off of my ZX550.2 either, but up until now the tweeters were just powered by the HU. so they will take 100 watts w/o a problem.
