[QUOTE="Steve in Seattl, post: 5659796, member: 607744"] I was recently given an enclosed sub and amp. The sub an Audiomobile MASS 2012, (made July 2001, per sticker on magnet). It's a 12" sub with a single voice coil... I assume it's 4 Ohms. 1) [B]Anyone know the max and RMS rating for this sub?[/B]I have an old amp that came with it that puts out 375W RMS @4ohms (bridged). Is this sub being substancially under-driven? 2) The surround is pretty thick and seems in good shape. Is [B]there a rule of thumb regarding RMS loads and the age of a sub? [/B] What kind of maintainence is needed to let this sub boom again? Thanks for your help.
