Unit is in perfect visual and working condition. Used very lightly over the past 6 months to power a Tempest for the 1st few months and then a BP 1804 for the past few. I am upgrading to a dual 1804 IB so I need more power. here is the owners manual in PDF form. http://bigchris.caraudioplanet.com/m_482052.pdf I need no less then $140 for the amp. I will add the actual shipping costs on to that. thanks for taking a look!! Chris ps. i do have one fellow i work with that wanted first dibs so if he comes through then it will go to him. but if not then it will go to the next in line.
