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 by a one year partsand- labor limited warranty. Please save your sales receipt and refer to the warranty section of this manual for complete details. © 2000 Directed Electronics, Inc.
