What's in a name? When it is the Ground Pounder from Crunch, the name is everything! The Crunch engineers approached the Ground Pounder with specific goals—design the ideal features for an amplifier like a great sounding preamp section and a versatile crossover with power that will POUND the GROUND. This 1,000 watt GP-1000.4 Crunch Ground Pounder Class AB 4 Channel Amp features nickel-plated preamp-level RCA inputs and screw-down connectors for quick, easy, and secure connections. Amp protection has system-diagnostics LEDs that indicate monitor overload and speaker short protection with lighted indicators on the amplifier end panel.
