For mid-bass/midrange settings, try to keep the setting low enough to keep your sound stage in front of you, without overdriving the speaker. It will be to your advantage to spend some extra time with this adjustment, listening to familiar music or system set-up discs to achieve the kind of musical reproduction that you prefer. • 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 setting on the amplifier and start to raise the head unit volume again. When you can listen to the music at or slightly above 3/4 on your head unit without audible distortion, slowly raise the gain of the amplifier until distortion is heard, then back off the gain until the distortion is not audible. This setting will allow you to reach full output with all but the quietest of source material, while avoiding excessive noise in the system. • The same procedure should be used for adjusting the amplifier when the on-board crossover is set to LPF or HPF, but you will also have to take into consideration the effect that gain adjustment has on system frequency response and imaging. Again, plan on spending some time with music that you know, getting the gain and crossover settings the way you like. Test discs and analyzers may help with this process, but in the end it's your ears that count - listen to the music! © 2003 Directed Electronics, Inc REAR PANEL CONNECTIONS 1.

Always use wire of the same gauge or larger than the (+) 12 volt power wire. The chassis connection point should be scraped free of paint and dirt. Use only quality crimped and/or soldered connectors at both ends of this wire. DO NOT connect this terminal directly to the vehicle battery ground terminal or any other factory ground points. © 2003 Directed Electronics, Inc © 2003 Directed Electronics, Inc 11 SPEAKER CONNECTIONS MONO CHANNEL 1500X FUSES SPEAKER 4 Ohm SPEAKER 4 Ohm TWO SPEAKER CONNECTION FUSES SPEAKER 2-4 Ohm ONE SPEAKER CONNECTION 25A fuses 25A fuses 12 © 2003 Directed Electronics, Inc TWO CHANNEL 2300X FOUR CHANNEL 4600X BRI BRI FUSES Note that the two speakers & four speakers have been connected to the four terminal following the (+) and (-) graphic.
