I have here 4-Kicker ZR1000's All amps have been serviced through Stillwater designs and are in perfect working condition Included are extra modules for either sub applications, or mid range. These amps are under-rated indeed and are hooked up currently for any one interested in listening to them before purchase. I also have many other audio accessories that too are in perfect working condition. All items have never been exposed to Alaska's elements. All have been housed inside my home
