    Great product so far always fast and prompt service
    The MTX Mud 100.4 was my top pick due to the design and the THD was lower than most and sounds amazing with the ssv works sound system that is offered as a factory system for the honda talon 1000r ssv works severely underpowered the speakers they give you 60 watt RMS speakers but the amp only gives you 25 watt RMS at best ...I would recommend this amp over all other big name amps.
