yea i called alpine and they told me it would be fine with one 10" type R.. but i really need confirmation from people not trying to sell me their product lolJust watch the gains and should be fine, although 500rms over recommened isn't the best thing for any speaker. However with that said, I have seen many people run 1000rms to them with no problems and others run 500rms to them and blow them. Just have to know what you are doing.
Good luck!
