i purchased an alpine type r thinking it was rated at 500wrms but i guess it was an older version rated at 300wrms. I bought an alpine m650 amp (600wrms) for it. will this be too much power for this sub? also, what are some possible consequences that may occur? thanks
"yes just dont turn the gain past halfway" That depends entirely on the HU - 1/2 could be WAY too much.
The point is - the amp's gain and the HU's volume control power to the sub. If you want to damage it I'm sure you can. If you want it to last a long time that can be done about as easily.
you will want to set the gains correctly to your head unit and then down some more, that sub doesnt handle 500+ watts very good ive tried :p and it died after bout a week
