1. 4 KICKER IM PULS U 3 A IX252 1X402 IX702 IX1302 IX2 302 Stereo Power Amplifier Congratulations You have just purchased one of the latest in a long line of exceptional car audio power amplifiers from Stillwater Designs Your KICKER Impulse was designed and engineered by the same team which created many other international award winning KICKER components like the ZR ZX and XS Series amps It contains a number of cutting edge features to give you outstanding performance and dependability when installed in a properly designed system Thanks for buying KICKER Enjoy KICKER IMPULSE AMPLIFIER FEATURES Two sets of RCA jacks on each Kicker Impulse amplifier allow you to build multiple amplifier systems without having to use RCA splitter cords to distribute the signal Now it is simply a matter of bringing one set of RCAs into the first amplifier then using the output RCA jacks as a feed to the next amplifier Amplifiers are stable at 2 Ohms stereo and as low as 4 Ohms in mono Input connections are included for high and low level signals for use with radios that have either RCA or speaker level outputs An electronic crossover is built in for convenience and allows you to select high pass for satellite soeakers low pass for subwoofers or bypass for full range operation In full range configuration the Kicker Impulse amplifiers will operate stereo and mono at the same time Auto resetting short circuit and overthermal protec2. to the amplifier This fuse has to be at least as high of a value as the amplifier is supplied with In line fuse and recommended wire size are as folows IX 2302 4Ga 80A fuse IX 1302 6Ga 50A fuse IX 702 8Ga 30A fuse IX 402 10Ga 20A fuse IX 252 12Ga 10A fuse 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 The ground wire should be as short as possible and attached to the body of the vehicle The ground point must be free from paint and corrosion Use the same size wire for ground connection as is used for power Mounting the KICKER Impulse Amplifier After determining an appropriate mounting location which provides good air circulation and access to the end panel controls use the supplied screws and washers to firmly mount the amplifier The amplifier chassis can be used as a template for the screw locations Check to make sure that the mounting screws will not damage any components on the back side of the chosen mounting surface If a vertical mounting surface is chosen it is recommended that the heatsink fins run vertically as shown for improved cooling esteses Basic Systems for the IMPULSE Two Channel Amplifier Stereo Two Channel FULL RANGE SPEAKERS INTERNAL CROSSOVER a CHANDEL TURNED OFF ot RCA IN E LILILIL o LLLLIILILILL
