[. . . ] Refer any repairs to a qualified service technician. · To avoid risk of electronic shock or damage to the unit, do not permit any of this equipment to become damp or wet from water or drinks. If this does occur, immediately unplug the power wires and send the product to your local dealer or service center as soon as possible. · If there is smoke or any peculiar odor present during use or if there is damage to any of the component enclosures, immediately unplug the power cord and send the product to your local dealer or service center as soon as possible . SHOCK HAZARD! [. . . ] Take special care when you work near the gas tank, fuel lines, hydraulic lines and electrical wiring. Never operate the subwoofer when it is unmounted. Attach all audio system components securely within the amplifier to prevent damage, especially in an accident. Do not mount this product so that wire connections are unprotected, in a pinched condition, in contact with any metal surfaces in your vehicle, or likely to be damaged by nearby objects. Before making or breaking power connections in your system, disconnect the vehicle battery. Confirm that your head unit or other equipment is turned off while connecting the input jacks and speaker terminals. If you need to replace the power fuse, replace it only with a fuse identical to that supplied with the product. Using a fuse of a different type or rating may result in damage to your audio system or your amplifier which is not covered by the manufacturer's warranty. Fuses Power fuses protect both the amplifier and the electrical system of your car from fault conditions. If you must replace a fuse in your BLX10DVC powered subwoofer, use a fuse of exactly the same type and rating. Using a different type or rating of fuse may result in damage to your amp or vehicle or cause a fire. BLX10DVC Amplified Subwoofer User's Manual - page 4 Mounting the subwoofer 1. Find a suitable location in the vehicle in which to mount the amplifier. Do not adjust this input level to maximum unless your input level requires it. Ignoring these instructions will result in an input overload to the amplifier in the subwoofer, and excessive audio distortion. It can also cause the protection circuit to engage.

The subwoofer will reproduce all sound BELOW the frequency you set. If the rest of your system is weak on the mids, you may wish to set this control relatively high. If the midrange is well covered by the rest of your system, you will probably want the subwoofer to only receive lower frequency signal. 2 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. Leave the control at this setting. 6 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. 3 SUBSONIC FILTER Use this control to filter out low frequency noise and rumble. 7 POWER STATUS LED This bi-color LED glows green when power is on and no problems are present.
