If the mounting surface is carpeted, measure the hole centers and mark with a felt tip pen.
Noise check and system adjustment NOISE CHECK Check the entire audio system for noise before permanently securing the CROSSOVER mounting 1. Start the engine. 2. Turn the audio system on. 3. Rev the engine and vary the VOLUME of the audio system to determine if there is any unwanted noise. If so, turn both the audio system and the engine off. Do not secure the CROSSOVER mounting screws. Refer to the "Trouble Shooting Guide" at this manual. 4.
TBOUBLE SHOOTING GUIDE PROBLEM 1. There is an audible distortion at a low volume level. 2. A whining sound can be heard through the speakers when the audio system is at low volume with the engine running. The whining noise remains unchanged or seems to disappear when the volume level is increased. POSSIBLE CAUSE • Output levels NOT set correctly. • Crossover frequencies NOT set correctly. • Check for shorts on the speaker leads. • Check the red power wire. It muse be connected directly to the battery.
