The AM Series of amplifiers were designed with the challenges of providing ample power to drive an entire system while keeping the overall footprint of the amplifier small. This was achieved by utilizing a 4 layer military spec circuit board incorporating the newest chipset from International Rectifier. With a 2 channel, 4 channel and a mono subwoofer amplifier, you now have the ability to enjoy your music without taking a lot of space. For added versatility, the mono amplifier (AM8001.D) incorporates a power optimization circuit that will provide full power into either 2 ohms or 1 ohm loads. So don't just settle for any mini amplifier if installation space is limited, select the Aunex AM series.
