JX Series
Jensen recommends that you have your
subwoofers professionally installed. If choosing
to do your own installation, please note the
following:
• Make sure all moving parts and factory
electrical wires are cleared.
• Leave slack in the wire to prevent pulling or
stretching.
• Tie down wires to prevent them from getting
caught or shorted.
• Do not mount subwoofers where they might be
subjected to moisture.
• Correct subwoofer polarity must be used. The
polarity positive side is marked by a (+) sign or
red dot. Subwoofers out-of-phase will have
little bass output.
• Speaker frames will be twisted by installation
on uneven surfaces. This occurs when the
surface is carpeted/padded and screws are
over-tightened.
• If using more than one subwoofers, be sure that
the combined impedance values cannot damage
the amplifier.
• Speaker wire should be isolated from the
vehicleís electrical system to avoid noise being
picked up by the amplifiers. We recommend
Road Gear or Sound Quest brands of wire.
• Speaker wire should be large enough to carry
the full power of the amplifier. 14 gauge or
larger sizes are adequate.
• Be sure to give your ears a break if you listen
loud. Listening loud for extended periods can
damage your hearing!
