1. use the supplied screws to firmly mount the amplifier Check to make sure that the mounting screws will not damage any components on the back side of the chosen panel NOTE The chassis of this amplifier is connected to signal ground for noise isolation It is important therefore to keep the chassis isolated from the metal of the vehicle If the best mounting location is part of the metal of the vehicle then it will be necessary to fabricate a nonconductive panel out of wood or plastic to mount the amplifier on If a vertical mounting surface is chosen it is recommended that the heatsink fins run vertically as shown 000000 EXPLANATION OF INPUT OPTIONS FOR THE IMPULSE 356xi The 356xi amplifier has five different options for hookup to your source unit 1 One pair of RCA cables 2 Two pairs of RCA cables 3 Three pairs of RCA cables 4 One stereo pair of high level inputs 5 Two stereo pairs of high level inputs The input selector switch allows you to select one or two inputs low level or high The sub channels get their signal from the front and rear inputs unless the sub inout RCAs are plugged in There is an automatic switching setup inside the sub input RCAs which disconnects the front and rear signal from the sub amplifiers when using separate sub RCAS Input Option 1 Using One Pair of RCA Cables With the input selector switch in Front Only position all six channels receive input from the front inp
2. 356xi Six Channel Power Amplifier The Impulse 356xi six channel power amplifier allows you to create an outstanding stereo system based on a single amplifier chassis Features and Controls The Impulse 356xi Amplifier is 2 Ohm stable on all six channels the sub out can be bridged to as low as 4 Ohm mono For connection to the source you have the option of low level RCA inputs or a high level input for use with radios that don t have RCA outputs Separate electronic crossovers built in for your convenience allow you to select full range or highpass for the front and rear channels as well as full range or lowpass for the sub output Separate KICKEQ bass and treble controls give you the ability to boost low and high frequencies to tailor the music to your taste Auto resetting short circuit and overthermal protection circuits are incorporated to protect the amplifier from failure due to extreme conditions State of the art circuitry including MOSFET power supply and glass epoxy circuit boards are used to ensure many years of trouble free operation Wiring Instructions The preferred method of bringing input signal to the amplifier is with RCA cables from a quality tape or CD player A high level speaker input signal may also be used if your factory deck or aftermarket source does not have low level RCA jacks OPTIONAL HIGH LEVEL IN R R L FRONT GROUND REMOTE TURN ON REAR Lt L R Ras 12V FUSE FRO

NT RCA IN REAR RCA IN SUB RCA IN SUB L FRONT amp REAR amp SUB SPEAKER OUTPUT L R Some of the system possibilities are shown in the System Diagrams section of this manual When working with power connections always hook up the ground wire first and disconnect the ground wire last Never make wiring changes with the amplifier powered up An inline fuse must be installed on the battery lead to protect the wire in the event of a short circuit Install a fuse of at least as high of a value as the total fuse value on the chassis of the amplifier within 18 inches of the battery connection For the 356xi a fuse value of 60A and 8 gauge power wire are recommended If the power wire is longer than 10 feet it is recommended that the wire size be 4 guage to reduce losses Any time that a power wire goes through a metal panel such as the firewall or if there is any chance of abrasion it is necessary to use a grommet or other suitable form of protection to avoid shorts Always use at least 8 gauge ground wire as short as possible and attach to the body of the vehicle The ground point must be clean and free from paint and corrosion To reduce the chance of noise entering the system it is recommended that the RCA cables be run through the vehicle separate from any power wires Mounting the IMPULSE Amplifier After determining an appropriate mounting location which provides good air circulation and access to the end panel controls
