With its deep-bass reproduction and plenty of reserve power, low harmonic distortion and neutral reproduction, the Power series of amplifiers takes Mobile Hi-Fi to new heights. Like all Jensen products, when it comes to accurate sound reproduction the Power series takes a back seat to no one. Jensen will bring your Hi-Fi experience to new heights with the following features: • MOSFET Power Supply • High Current Bi-Polar Output Transistors • Optimized Class B Design Minimizes Distortion and Reduc

WARNING: Do not cover the amplifier with carpets or enclose it behind interior trim panels, and do not mount the amplifier in an inverted or upside down configuration. Be sure the mounting location and the drilling of pilot holes will not damage any wires, control cables, fuel lines, fuel tanks, hydraulic lines or other vehicle systems or components. Routing Wires Proper wiring connections are illustrated on the following pages. If wiring connections are made incorrectly, the unit will not opera

Turn up the receiver volume slightly. All speakers should operate. If not, check wiring connections at amplifier and speakers. Test Speaker Connections These tests make sure the speakers are connected properly. If speakers don’t play at all, one (or both) speaker wires may be disconnected. Remote Input Level Control The Power 900 and 1050 come equipped with a Remote Input Level Control. The Remote Input Level Control allows the input level to be adjusted from an alternate location. It can be mou

Test Speaker Connections These tests make sure the speakers are connected properly. If speakers don’t play at all, one (or both) speaker wires may be disconnected. Pruebas Antes de finalizar la instalacion, usted debe realizar la siguiente prueba para asegurarse que el cableado este correctamente realizado y que todo esta operando correctamente. Reconectar la Bateria Cuando el cableado este totalmente realizado, reconecte el terminal negativo de la bateria. Pruebe el Cableado de Energia Prenda e

The amplifier will remain off until it cools to a safe operating temperature. Exercise care, as the exterior of the amplifier may get uncomfortably hot to the touch before shutting down. Overload and Short Circuit Protection The amplifier will shut down if a short circuit condition exists or if electical current demands exceed safe levels. Remote Bass Control Remote bass control allows the input level to be adjusted from an alternate location. It can be mounted under-dash or in-dash. When the am

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 is the true power you are getting. At Jensen, to be fair to you and to the competition, we rate our amps in the two most popular ratings, incl
