This Lanzar Heritage Series 2 000 Watt Monoblock Series Amplifier provides high-performance sound reinforcement at its best. RCA connectors ensure a secure connection between this amplifier and your subwoofer for distortion-free sound. This monoblock amp includes power and protection LED indicators soft turn-on/off and is budget-friendly. The line outputs allow you to build multiple amplifier systems without having to use splitter cords to distribute the signal. That makes it easier to bring 1 set into the first amp then use the line out jack as the feed to the next amp.
