(High pass) C= 159000 fc x R (.F) fc=Cut of Frequency (Hz) Frequency L= 159 x R fc (mH) R=Speaker Impedance (.) .Example: L C 0 dB -3 dB Crossover Frequency Coil (L): Passes low frequencies and blocks high frequencies. (Low pass) Capacitor (C): Passes high frequencies and blocks low When it is required to set a crossover frequency of 120 Hz using speakers with an impedance of 4 ohms. Prepare commercially-available coil and capacitor with the closest ratings to the results calculated from the formula above. The capacitor rating should be as close as possible to 331.25 (.F) and the coil rating should be as close as possible to 5.3 (mH). 2CAUTION • If you wish to bridge-connect a speaker, the speaker impedance must be no less than 4 ohms. Connecting a speaker with an impedance lower than 4 ohms may damage the unit. • Be sure to connect capacitors to speakers to which high frequencies will be passed. Failure to do so will result in a drop of the combined impedance with the subwoofer. • Ensure that the withstand voltage and current ratings of the capacitors (C) and coils (L) are sufficient. English 11 Troubleshooting Guide Troubleshooting Guide PROBLEM POSSIBLE CAUSE SOLUTION No sound. • Input (or output) cables are (No sound from one side.) disconnected. • Protection circuit may be activated. (Blown fuse.) • Volume is too high. • The speaker cord is shorted. • Connect the input (or output) cables. • Check connections by referring to "Indicator". • Replace the fuse and use lower volume. • After check the speaker cord and fixing the cause of the short, replace the fuse. The output level is too small (or too large). The input sensitivity adjusting control is not set to the correct position. Adjust the control correctly referring to “Controls”. The sound quality is bad. (The sound is distorted.) • The speakers wire are connected with wrong + / polarity. •A speaker wire is pinched by a screw in the car body. • The switches may be set improperly. • Connect them properly checking the + / -of the terminals and wires well. • Connect the speaker wire again so that it is not pinched by anything. • Set switches properly by referring to "System examples".
