D. CROSSOVER FILTER SLOPE SELECTION

     When the high-pass crossover point is set close to the speaker's frequency    
     response roll-off of 12 dB per octave (even order), by selecting the 6 dB per    
     octave high-pass crossover slope, the combined effect is the ideal odd order  
     (18 dB) filter type frequency response. When the high-pass crossover point is  
     set away from the speaker's resonance frequency, the 18 dB per octave slope  
     filter can be used.

E. NOISE CHECK

     Before mounting the crossover and the other audio components permanently,
     please conduct the following noise check:
     1. Start the engine and turn on the power of the source unit.
     2. Rev the engine and vary the audio volume to check for radiated engine
         noise. If there is an alternator whining noise or tic-tic noise, refer to the
         

TROUBLESHOOTING

 for assistance.

     3. If no unwanted noise is detected, double check all the wiring and cables
         for safe placement. Then securely tighten the mounting screws of all the
         audio components.
