Installation Assistance
For installation assistance, call 888-921-4088 during normal business hours, or
visit www.jensenmobile.com at any time.
Supplies and Tools
To install the amplifier, you will need tools, supplies and adapters. It is best to
make sure you have everything you need before you start.
Disconnect Battery
Disconnect the negative (-) battery cable before starting the installation. Check
the battery ground (there should be two (2) ground wires coming from the
battery – one going to the starter mounting bolt or engine block and another
going to the vehicle chassis) and make sure the battery is grounded to the
chassis with at least a #8 gauge wire. Also check the alternator connections,
making sure they are tight and free from corrosion, rust or dirt.
Location and Mounting
The amplifier’s compact design allows great flexibility in mounting. Common
mounting locations include under the front passenger seat or in the trunk area.
When selecting a location, remember that amplifiers generate heat. Select a
location on a flat surface away from heat and moisture where air can circulate
around the amplifier.

Remote Terminal (Turn-On)
Connect the power antenna or amplifier turn-on lead (Switched +12VDC)
from the receiver to the amplifier remote terminal.
Power Terminal (+12V) and Ground Terminal (Gnd)
Connect the main power wire to the battery, within 18 inches from the positive
(+) battery post, use an adequate size fuse or circuit breaker capable of
handling the current of the selected power wire. A fuse or circuit breaker must
be installed to prevent a possible electrical fire should the main power wire
short to ground.

Battery Terminal
Adapter
Make the ground lead as short as possible, leaving enough length to complete
the installation. To ensure a good ground, scrape away any paint or
undercoating to expose bare metal. Use a "ring" terminal of the proper gauge
and an "outside star washer" (between the chassis and ring terminal) when
making your ground connection.
