I have both of my HK Citation 5.1 Amps for sale. Pics and description of the amp can be seen here. The amp is very flexible and can be configured at 4 channel 4x100, 3 channel 1x300-2x100 and 2 channel 2x300. It has a 12v trigger. It weighs in at over 60lbs and 75 lbs packed. I guarantee the amp to exceed your expectations for cosmetic condition. I have the original double box for shipping. My price is $600 plus shipping. Please email me with questions or offers as I do not get to check PM that often. Thanks for looking.
