Installation
Before you begin the installation of your PowerPlus series amp remember,
there are two ways to do things – right and twice! Use the proper installation
techniques, tools and accessories to ensure that your Jensen PowerPlus
series amp will put out all the power it was designed to. If necessary, seek a
professional installer to have the amplifier installed correctly. Most mobile amp
installations do not have the proper gauge wire for power and ground – do not
let your amp be a victim of this common installation oversight!
NOTE: This device is a high-power audio amplifier intended for
installation in vehicles with a 12-Volt negative ground electrical system.
Attempting to connect or operate the amplifier with another type of
electrical system may cause damage to the amplifier or the electrical
system.

Supplies and Tools Needed
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.
Supplies
• Black electrical tape
• Amplifier Installation Kit
Tools
• Cordless drill with assortment of bits
• Flat-head and Philips screwdrivers
• Wire cutters/strippers
• Crimping tool
• 12-volt test light or digital multimeter
• Wire brush, sandpaper or scraping tool (ground connection to vehicle should
be a clean, unpainted metal surface)
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.
Place the amplifier in the mounting location and mark the positions of the holes
with a marker, pen or pencil. Carefully drill the mounting holes in the marked
positions, then use the supplied mounting screws to securely fasten the
amplifier to the mounting surface.
WARNING: Do not cover the amplifier with carpets or enclose it behind
interior trim panels, and do not mount the amplifier in an inverted or
upside down configuration. Be sure the mounting location and the
drilling of pilot holes will not damage any wires, control cables, fuel
lines, fuel tanks, hydraulic lines or other vehicle systems or components.
Routing Wires
Proper wiring connections are illustrated on the following pages. If wiring
connections are made incorrectly, the unit will not operate properly and could
become permanently damaged. Follow the installation instructions carefully, or
have the amplifier installed by an experienced technician.
