This is one amazing piece of equipment. I'm the second owner (the first fellow kept immaculate care of it) and it's been 100% reliable. I use this amp in bridged mode with both my SWR cabs and the sound is absolutely righteous. Tons of low end and crystal clear mids and highs. No fan, no noise. 350/550w per side at 8/4 Ohms 1,100/1,500w bridged at 8/4 Ohms http://www.crownaudio.com/amp_htm/k.htm Asking $500 firm plus shipping. I don't do online payment options so I prefer certified or USPS check. Contact me at firstname.lastname@example.org if interested.
