[QUOTE="BoomTaco64, post: 8260989, member: 659681"] hate to break it to you but your alpine type r sub in not 1000w rms nor would i put that much power on that sub. its the same sub that they have been making for the last few years and magically the rms keeps going up every year. having your radio volume at its peak before distortion is best for the amp. i have tested many radios with o-scopes and DMM's and a lot of them will have a full output without distortion or at least 95% of the available volume. when you put a higher voltage into the amp the gain will not be turned up that much and the amp will work a little bit less in order to achieve the power you were looking for. Dont believe it, Test it your self and see the results. My factory 2001 toyota tacoma non tape, non cd player ratio had a 9v output on the speaker wires and un-clipped signal at full volume. My kenwood excelon kdc-x395 has no distortion on the rca outputs until level 35(Max volume) and i have the almost full 4v ac output at 34/35(3.943v ac). on the speaker wire output i get a full volume output un-clipped at 35 and get 9.258v ac from them.
