manual abstract
Directed has been the leader in high-quality and innovative security products in the U.S. since 1990. Now we introduce to the car audio industry the same winning formula - products that meet the stringent standards of today’s mobile electronics enthusiast yet priced for anyone’s budget. Featuring high-efficiency MOSFET power supplies, flexible on-board crossovers, and state-of-the-art audio design, Directed Audio amplifiers will satisfy every music lover’s needs for years to come. Your Directed Audio power amplifier comes with a two year limited warranty if it is installed by an authorized DEI dealer. Amplifiers not installed by an authorized Directed dealer are covered are covered by a one year parts-and-labor limited warranty. Please save your sales receipt and refer to the warranty section of this manual for complete details. © 1999 Directed Electronics, Inc TABLE OF CONTENTS Installation Guidelines . . . . . . . . . . . . . . . . . . . . . . . . . . . .Page 2 Amplifier Connections . . . . . . . . . . . . . . . . . . . . . . . . . . . .Page 4 Amplifier Controls . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .Page 5 Speaker Wiring Diagrams . . . . . . . . . . . . . . . . . . . . . . . . .Page 6 Crossover Setting and Gain Adjustment . . . . . . . . . . . . . . . .Page 7 Specification . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .Page 8 Warranty . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .Page 9 WARNING High-powered car audio systems may produce sound pressure levels that exceed the threshold at which hearing loss may result. They may also impair a driver’s ability to hear traffic sounds or emergency vehicles. Use common sense and practice safe listening habits when listening to or adjusting your audio system. © 1999 Directed Electronics, Inc INSTALLATION GUIDELINES 1.
