PowerPlus Amplifiers Introduction The Jensen PowerPlus series of amplifiers were designed to meet or exceed the CEA-2006 test standards. These new standards give all participating manufacturers (and many don't participate) a baseline when comparing amplifiers of similar power output. The CEA Power rating protects you, the customer. “Power is power – it doesn't matter who makes it,” is not always true. What does matter is whether the power can be produced in the first place. The RMS rating

PowerPlus Amplifiers Ground Terminal (GND) Make the ground lead as short as possible, leaving enough length to complete the installation and to allow for any service that may be needed at a later date. To ensure a good ground, scrape away any paint or undercoating to expose bare metal. Use a "ring" terminal of the proper gauge and an "outside star washer" (between the chassis and ring terminal) when making your ground connection. Although you’ve scraped away the paint to expose bare metal,
