Remember, the amplifier can only deliver its rated output when it is not current limited by the power and ground supply wires. This amplifier is designed to drive a speaker load that measures from 2 to 8 ohms. Keep in mind that heat is the long-term enemy of automotive electronics and the lower your © 2003 Directed Electronics, Inc speaker load, the more heat is generated. For low impedance speaker applications or restricted ventilation installations, an external cooling fan may be advisable. 9.

• The gain adjustment allows you to set proper signal match for clean, quiet amplifier operation. For full-range and simultaneous stereo/mono bass applications, start by playing some music you are familiar with. With the gain adjustment on the amplifier in the middle of its rotation, bring up the volume on your head unit to the 3/4 volume setting or until you start to hear distortion or clipping. If you hear distortion before you reach the 3/4 volume setting of your head unit, reduce the gain se
