I need a new amplifier for my two subwoofers and have been offered a used Crown MAi12000 (http://www.crownaudio.com/en/products/ma-12000i) which meets my requirement perfectly!

It is used and from 2009 so definately not new anymore. Would you have any concerns regarding buying such an old amp? The price is really good and it doesn't look like it has been thrown around.

Appreciate the input!
