Had this sub Aug 2009 but amp only last for 2 yrs. Send amp for repair then dead after 6 mos. and they offered me a new amp LT 300 because they can't repair it anymore. Any other amps you can suggest that would last. I had an old Jamo 400E that until now still rolling for 16 yrs. Bad USA now relying on china made electronic components. Never ED sub anymore.....
