Compact and Powerful

This turned out to be the compact amplifier it was advertised to be. Sounds warm running it full pass as a 4ch on the headunit HPF. It fit into my glovebox comfortably. Plenty of headroom for my application power wise. It swallowed up 4AWG EB-Flex welding wire. Being open box, it arrived without allen keys or most of the mounting screws, the only evidence of prior use was the mounting feet being worn. The box had obviously been dispatched returned and then sent to me, it was pretty beat but appropriately packaged.
