JP 8 AMP: 800W PLUS RMS MONOBLOCK Amplifier The JP8 might be the most overdone, 800 watt amplifier ever to hit the market. R&D in Las Vegas, NV & Dunnellon FL. The Heatsink carries over from the JP23. The blue color takes from the OG days of Down4Sound and Car Audio, we call it OLD SKOOL BLUE. Inside the JP8 is a fan cooling the output side; now it has plexi black plate, and NEW ALUMINUM Bass Knob with voltage and temperature meter.
