Please observe the following installation tips: When using the high-level input con- nections, BassPro will automatically turn on when

8、you turn on your radio. In this case, the remote (REM) con- nection is not needed. Use at least #20 AWG speaker wire for speaker-level input connections. Use at least #12 AWG wire for the Positive Battery (BATT +12) and Ground ( ) connections. If needed, use at least #20 AWG wire for the remote (REM

9、) turn-on connection. Connect BassPros “BATT +12V” terminal directly to the batterys posi- tive (+) terminal. Install a fuse holder, with a 20A fuse, within 18 of the bat- terys positive (+) terminal. BassPro (right-side panel) Chassis Ground (Bare Metal) Source Unit Battery Fuse 20 A 18 Remote Turn

10、-On Route all power wires through a grom- met in the vehicles firewall. If a factory grommet is not available, install one. Connect a short ground wire from BassPros ground terminal ( ) to the nearest bare metal surface. For a good connection, use sandpaper to clear paint from the metal surface and

11、use a screw with a lock (star) washer. The remote (REM) connection requires a +5 to +12 Vdc signal for BassPro to turn on when using the line-level connections. Most head units with preamp outputs provide this remote voltage signal. As an alternative, connect this terminal to a switched ignition cir

These controls are located on the amplifier panel, as shown in Figure 10. Power LED Gain Control Crossover Remote Bass

16、 Control Auto Turn-On POWER LED: This indicator will glow red when the BassPro is operating. GAIN CONTROL: Use this control to adjust the relative volume (loudness) of BassPro with the other speakers in the vehicle. CROSSOVER: Use this control to adjust the amount of high-frequency information prese

17、nt in BassPros out- put. A lower value signifies less high- frequency content. 3. Turn the head unit ON and play a selection of your favorite music track that has substantial bass. 4. Adjust the CROSSOVER control counterclockwise, until you hear only low-frequency information. Example you should not

18、 hear vocals coming from BassPro when seated in the normal listening position. 5. Adjust the BASS CONTROL either clockwise or counterclockwise to suit your taste, and to avoid audible distortion. 6. If you elect to not install the Remote Bass Control, adjust the GAIN control to the maximum level tha

However, the actual process may require several readjustments of each control, since the settings will interact

20、with one another. If necessary, consult your authorized JBL car audio dealer for help in tuning your system. AUTO TURN-ON: For speaker- level connections, used this switch to activate (or deactivate) BassPros automatic turn-on circuit. For most speaker-level applications, slide the switch to the AUT

21、O position. If you prefer to use the remote (REM) connection, slide the switch to the OFF position. REMOTE BASS CONTROL: Use this RJ-11 jack to connect the supplied remote bass control. SETTING THE CONTROLS: 1. Make sure the head unit is off and VOLUME control is set to minimum. 2. On BassPros ampli

22、fier panel, set the CROSSOVER to its maximum frequency of 120Hz, as shown in Figure 10. Note: If using the REMOTE BASS CONTROL, set GAIN to maximum and set the BASS CONTROL to the midpoint. 5 Figure 10.

Feed the Subwoofer Level Controls potentiometer shaft (with the knob removed) through the hole and use the nut and washer provided to hold the control in place (Figure 5). Route the cable behind the dash or other interior panels and under the carpet

27、. Do not route the cable outside the vehicle. Connect the RJ11 cable between the RJ11 receptacle on the BassPro and the receptacle on the Subwoofer Level Control (Figure 6).
