User manual AUDIOVOX POWER AMPLIFIERS 760

[. . . ] Please be responsible and have respect for other people by listening at moderate volumes!If your Jensen amplifier should ever require service, you will need the original dated receipt. If you must return the unit for any reason, always include the receipt with the product. Your new Jensen Power mobile stereo power amplifier is the amplifier of choice for the high demands of auto sound reproduction. [. . . ] Adding capacitors and/or batteries without upgrading the alternator will only make the problem worse because these devices put an extra load on the alternator. After upgrading the alternator, capacitors and/or batteries can be installed if desired. Use the following recommended wire gauge as a guide when installing your amplifier(s): MODEL NUMBER 400 760 880 900 920 1050 MAX CURRENT DRAW 25A 40A 60A 60A 60A 100A MIN WIRE GAUGE #8 #8 #6 #6 #6 #4 Connect the main power wire to the battery, within 18 inches from the positive (+) battery post, using an adequate size fuse or circuit breaker capable of handling the current of the selected power wire. A fuse or circuit breaker must be installed to prevent a possible electrical fire should the main power wire short to ground. Connect the power antenna or amplifier turn-on lead from the receiver to the amplifier remote terminal. 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, the outside star washer will help to "bite into" the chassis for a tight, secure ground. NOTE: Power amplifiers can drive speakers with a nominal impedance range of 2~ 4-ohms. Most trunk/hatchback installations will require a 15-20 foot RCA cable, while pickup trucks and under-seat mounting will require a 6-12 foot RCA cable. Connect an RCA cable from your receiver to the RCA input on your amplifier. The Power 760 and 920 can be configured for three different input modes: 2 channel, 3 channel or 4 channel. NOTE: The use of good quality RCA cables is just as important as power and speaker wire. Pass-Thru RCA connectors are provided to connect additional amplifiers without the need to purchase "Y" adapters. The power indicator provides a visual indication that the amplifier is turned on. Select LPF (low pass filter) when the amplifier will be driving woofers or subwoofers. Choose FULL when crossover mode is not active and the amplifier is in "full range" mode. Select HPF (high pass filter) when the amplifier will be driving full-range or separate speakers, and you want to limit the "bass" being transferred to these speakers. After the installation is complete, make sure the input level control on the amplifier is turned down all the way (counter-clockwise or all the way to the left).
