ZX460
4–CHANNEL POWER AMPLIFIER
Based on the same design philosophy as the original KICKER Amplifier,
the ZX460 four–channel amplifier from Stillwater Designs expands and
improves the standards for car audio amplifier performance. Features that
defined the way an amplifier should be built, attention to detail, flexibility,
and pure clean power have been retained and some important new
performance/reliability features have been added.

MOUNTING INSTRUCTIONS The orientation of the amplifier is critical to proper cooling. The cooling fins are designed to operate best when the amp is in a vertical position or mounted flat with the fins up. It is important to keep the chassis of the amplifier isolated from the metal of the vehicle because the heatsink is connected to signal ground for noise isolation. Grounding the heatsink will cause a ground loop. The plastic inserts in the mounting feet of the amp should remain in place as isol

WIRING INSTRUCTIONS All power and speaker connectors will accept up to 8 gauge wire. It is very important that the screws in the amplifiers’ terminal strips are very tight. An allen wrench is included for this purpose. Always make the ground connection first when installing this amplifier and disconnect ground last when removing it from the system. Connect the ground wire, which is 24 inches or less, to a structural chassis member. Be sure the connection is to bare metal and securely screwed or

SPECIAL FEATURES • To understand all the different system possibilities, think of the KICKER ZX460 as two separate amplifiers in one chassis: Amp 1 and Amp 2, each having two channels. • When only two RCA cables are plugged into the Amp 1 inputs, the ZX460 automatically distributes the left channel to Amp 1 left and Amp 2 left. The right input goes to Amp 1 right and Amp 2 right. • Plugging in a second set of RCAs automatically switches the ZX460 to discreet four channel operation. • Amp 2 has

OPTIONAL ACTIVE SIGNAL PROCESSING MODULES All KICKER amplifiers have a Module Docking Port, which allows the use of any KICKER Module. These modules greatly increase your amplifier’s versatility, and cost very little when compared to “stand alone” units with the same functions. Active Crossover Modules: These 2-way modules allow you to use separate amplifiers for your subwoofers, midbass drivers, midranges, or tweeters. By doing this, especially on the subwoofer, a clean and undistorted sound i

TROUBLE SHOOTING Note: It is normal for the yellow trouble LED to blink when the amplifier is turned on or off. This is a function of the protection circuit looking for trouble. Red LED power indicator off, yellow trouble indicator off. With a Volt Ohm Meter (VOM): • Check +12 Volt terminal • Check Ground terminal • Check for +12 Volts at remote turn-on terminal Red LED power indicator on, yellow trouble indicator off: • Make sure there is a module in place and the settings are correct • Check
