Insist on getting the best, DB Link .TM It's what you deserve to get the optimum performance from your audio System. IMPORTANT! Before making any connections, disconnect the car's battery until the installation is completed to avoid possible damage to the electrical system. WARNING!

Use common sense when listening to your system. Serial #____________________________________ M_odel #___________________________________ 1 Panel Controls and Features H D E A J K I C B G F A. POWER STATUS LED This bi-color LED glows green when power is on and no problems are present. If one of the protection circuits comes on, it will change to red. B. PHASE SHIFT Use this switch to help compensate for time alignment problems in the system. Such problems usually result from having the subwoofer at a different distance from the listener than the other speakers in the system. F. INPUT GAIN CONTROL After you have installed your system, turn this control to minimum. Turn the head unit on (and the subwoofer will turn on via the remote connection). Turn the head unit volume to about 2/3 full level. Slowly turn up the subwoofer input gain control until you hear a small amount of distortion. Then reduce the level until the distortion is completely gone. Level the control at this setting. C. AUTO POWER ON The AUTO POWER ON (ON/OFF) is for high level (speaker-level) connections. When the switch is in the "ON" position, the subwoofer AUTO POWERS ON when there is signal input. If the amplifier detected no signal input, the amplifier will auto turn off. If you prefer to use the remote turn on/off connection, the switch is in the OFF position. D. LOW PASS FILTER This control permits you define the frequency range you want the subwoofer amplifier to receive. The subwoofer will reproduce all sound BELOW the frequency you set. E. BASS BOOST The BASS BOOST feature will increase the sound level in the bass frequencies. G. REMOTE LEVEL CONTROL PORT Attach the included remote level control to control the volume level of the subwoofer independently. H. HIGH LEVEL (speaker level) INPUTS If your head unit does not have RCA outputs you can use the speaker outputs for the audio source for the subwoofer. Use the supplied cable and wire harness and connect the outputs properly as shown in the connection diagram in this manual. I. LOW LEVEL RCA INPUTS If RCA outputs are present on your head unit low level inputs are the recommended way to introduce the audio signal into your subwoofer. J. FUSE Do not use a fuse with different value other than the original value. K. POWER INPUT TERMINAL 2 I. Low Level Input Wiring Low-level (RCA) input wiring is preferred for best audio performance. Most trunk or hatchback installations will require a 15-20 foot RCA cable, while pickup trucks and under-seat installations will require a 6-12 foot RCA cable. Always use a high quality cable. NOTE: Do not connect BOTH the high level and low level inputs from your receiver to your amplifier at the same time! Fig.1 To Audio outputs of head unit or signal processor H. High Level Input Wiring The high level input(s) should only be used when your receiver lacks RCA outputs. If the RCA outputs are not present, connect the speaker outputs from the receiver to the high level input connector of the amplifier. Be sure to observe polarity to avoid audio phase problems. NOTE: Do not connect BOTH the high level and low level inputs from your receiver to your amplifier at the same time! R- GREY/BLACK L- WHITE/BLACK GREY R+ WHITE L+ To Speaker Terminals of head unit 3 Power Connections Connect the ground terminal to the closest point on the chassis of the vehicle. Keep this ground wire to less than 39" (100cm) in length. Use 8 gauge (or heavier) wire. Connect the remote terminal to the remote output of the head unit using 16 gauge (or heavier) wire. Connect any empty fuse holder within 18" (45cm) of the car battery, and run 8 gauge (or heavier) cable from this fuse to the amplifier location. Then connect the fuse holder to the "BATT+" (+12V) connection on the subwoofer rear panel. Fig.3 FUSE BATTERY Fig.4 NOTE: in this connection, the AUTO TURN ON switch is in the ON position. FUSE BATTERY NOTE: in this connection, the AUTO TURN ON switch is in the OFF position. 4 Remote Level Control Connection Remote Level Control Install the remote control securely under the dash or in a similar location where using it will not distract the driver.

If the problem persist, read the following troubleshooting tips which may help eliminate the problems. POSSIBLE REMEDY Check to make sure you have a good ground connection. Check that the Remote input (Turn-On) has at least 5VDC. Check that there is battery power on the (+) terminal. Check that there is at least 12v. Check all fuses, replace if necessary. Make sure that the protection LED is not illuminated. If it is lit, shut off the amplifier briefly, and then repower it. Check for short circuits on speaker leads. Turn down the volume control on the head unit to prevent over- driving. Check that there is good air circulation around the amp. Check that all fuses are OK. Check that unit is properly grounded. Check that the Remote input (Turn-On) has at least 5VDC Check that the RCA Audio cables are plugged into the proper inputs. Check all speaker wiring. Reset the Level Control. Check the Crossover Control settings. Check that Input Level Control is set to match the signal level of the head unit. Always try to set the Input Level as low as possible. Check that all crossover frequencies are properly set. Check for short circuits on the speaker leads. Check that the minimum speaker impedance for the amp model is correct. Check that there is good air circulation around the amp. In some applications, it may be necessary to add an external cooling fan. 6 LIMITED WARRANTY DB DriveTM warrants any products purchased in the U.S.A. from an authorized DB DriveTM dealer.
