I am selling an open box GZHA One-K from Ground Zero. The amplifier has never seen power. It has been taken out of the box several times to ensure fitment in a possible build. Due to that, one of the corners of the heatsink has a tiny little chip in the paint (barely noticeable). This is a great quality monoblock amp for anyone needing one that can fit in a small space. Shipping is on me within the USA.
