JP 23 AMP: 2300W RMS MONOBLOCK Amplifier V1.5 VERSION: 1.5 features a thick PLEXI BackPlate; we also UPGRADED a resistor to make the amplifiers even more unbeatable. The JP23 might be the most overdone, 2300 watt amplifier ever to hit the market. R&D in Las Vegas, NV & Dunnellon FL with the brightest minds historically in-car audio dating back to the late '90s thru the 2000s AND TODAY. We took the old school approach of building a quality amplifier, heavy heatsink, and quality hardware. Then we applied what our basshead clientele wants with technology, durability, and features for both competition and daily use. Inside the JP23 is a fan cooling the output side; and Bass Knob with voltage and temperature meter. The JP23 fans turn on at 120 degrees or when the amplifier detects electrical stress and excessive heat during playtime.
