CONGRATULATIONS Congratulations for choosing a Viper Audio power amplifier from Directed Electronics, the industry leader in high quality automotive security and audio equipment since 1990. With the introduction of Viper Audio power amplifiers, Directed Electronics continues to set new standards of performance, reliability, and affordability in the mobile electronics industry.
LIMITED TWO-YEAR CONSUMER WARRANTY Directed Electronics, Inc. promises to the original purchaser, to replace this product should it prove to be defective in workman- ship or material under normal use, for a period of two years from the date of purchase by the dealer as indicated by the date code marking of the product PROVIDED the product was installed by an...
FEATURES Super-efficient Class D PWM design runs much cooler than conventional amps. High-speed MOSFET switching power supply. High-current complimentary MOSFET outputs stable into 1 ohm loads. Thermal, DC offset, reverse polarity, and short circuit protection with status LED. Master/slave RCA jack functions support two amps bridged to one load.
INSTALLATION GUIDELINES 1. Please read this owner’s manual carefully before installing this ampli- fier. 2. Disconnect the battery ground terminal prior to making any elec- trical connections. 3. Check for any hazards or obstruc- tions such as gas tanks, fuel or brake lines, and wiring harnesses before mounting the amplifier.
speaker load, the more heat is generated. For low-impedance speaker applications or restricted ventilation installations, an external cooling fan may be advisable. 9. Battery and ground connections to the vehicle should be made with crimped ring terminals of the appro- priate size (surface area is what counts);...

SPEAKER WIRING DIAGRAMS Single subwoofer connection (bottom view) Two subwoofer connection (bottom view) N N O O T T E E : : The dual + and -- subout terminals of the d600.1/d1200.1 are paralleled internally and the combined load impedance should be taken into consideration when connecting multiple subwoofers.
COMBINING AMPLIFIERS The Viper d600.1/d1200.1 subwoofer amplifiers have the capability of connecting two or more amplifiers of the same power rating together in a master/slave combination for increased power with accurate level matching. They are the Parallel Synced Gain and External Synced Bridged combinations.

MULTIPLE AMPLIFIER COMBINATIONS The Viper d600.1/1200.1 subwoofer amplifiers can also be used in multiples of the master/slave combinations allowing for unlimited expansion to a systems subwoofer section. To use multiples of amplifier combinations the following directions must be adhered to for best results.
CROSSOVER SETTINGS AND GAIN ADJUSTMENT Your Viper Audio power amplifier needs to be adjusted carefully to achieve maximum performance. These are some guidelines to follow when fine-tuning the amplifier. Because this amplifier is only designed for subwoofer applications, the low-pass crossover is active at all times.
SPECIFICATIONS d600.1/d1200.1 RMS continuous power driven into 4 ohms from 20 to 250 Hz @ 14.4 VDC at rated power/load. RMS continuous power driven into 2 ohms from 20 to 250 Hz @ 14.4 VDC at rated power/load. RMS continuous power driven into 1 ohm from 20 to 250 Hz @ 14.4 VDC at rated power/load.
