I have a performance teknique icbm-782 digital monoblock (2000)w max. anyways i just got a new head unit in my car and my speakers work fine but my amp will not power on i thought it might be a fuse or a connection problem so i tested it and all the wires are getting power running to the amp. Could it be a fuse in the amp or ? please help!!!
