I purchased three of these from CopperElectronics on 3/24/2021 for each vehicle but sold my vehicles and downsized to one. These are no longer needed. This is the. HD version (a little difficult to find these days). Brand new in box never turned on. Included with the amplifier is a 2.5 feet power cord with pin terminals on one end and an Anderson Powerpole SB50 on the other end. (10 gauge silicone tinned copper wire).

I’ve posted a picture of power output using my other KL-503HD. The pin terminals have been hexagon crimped and the powerpole connector has been “flood soldered” then shrink wrapped.

Do NOT over volt or over drive! You will let the smoke out.

Asking $175. Price includes paypal and shipping CONUS. Email/PM me here.
