INSTALLATION

Note: Verify that your vehicle does not have a positive ground electrical system,
this is very rare. A positive ground system is the reverse of most standard
vehicles in that the + battery terminal is connected to the vehicle chassis and is
typically found in some older European vehicles. If you have any questions do
not proceed until you have veriﬁed this. If it is a positive ground electrical system
please contact your dealer for assistance.

Caution: Please follow all the installation recommendations and instructions
in this manual. Installation in any manner not outlined in the manual will
void your warranty and may possibly cause damage to the vehicle and/or
the ampliﬁer.

Warning: The battery ground should remain DISCONNECTED at all stages
of installation.

LOCATION/MOUNTING
When selecting a location to mount your ampliﬁer, please keep in mind that
electronics are sensitive to vibration, moisture, and heat. Make sure the ampliﬁer
is mounted in an area with ample ventilation and is not exposed to moisture or
external heat. For proper cooling, it is recommended to mount the ampliﬁer
horizontal or vertical but not upside-down. Automobiles have a certain level
of normal vibration and we have designed the product with this in mind, but
excessive vibration may cause damage over time. Using the ampliﬁer for a
template, mark the mounting holes in your selected area while following the
preceding guidelines. Verify that you are not going to damage sensitive vehicle
systems by drilling where you have selected (look for gas tank, wires, etc…).
Remove the ampliﬁer and pre-drill the locations for size screws/bolts that you
have selected that ﬁt the ampliﬁer and your installation purposes, permanently
mount the ampliﬁer to selected location.

Figure 3. Typical System connection

Note: It is best to mount the ampliﬁer to some form of insulating surface, such
as MDF, so that the chassis of the ampliﬁer does not come in contact with the
vehicle chassis (if a single screw makes contact with both the ampliﬁer and
vehicle chassis, it is the same as no insulator). This will lessen the possibility of
any ground related noises and will shield minor amounts of radiated noises.

INPUT CONNECTIONS
Connect RCA input jacks of the Ampliﬁer to the output of the Source Unit (i.e.
Radio, Cassette player or CD player).

SPEAKER CONNECTIONS
When connecting the Ampliﬁer to the Speakers, use heavy gauge speaker wires
for these connections (16AWG minimum for stereo and 14AWG minimum for
mono/bridged).

FOR STEREO MODE
Note: We recommend that the total speaker load is no less than 2 ohms per
channel

Connect the Right (+) and (– ) speaker output terminals of the ampliﬁer to the
corresponding (+) and (–) terminals of the Right side speaker. Connect the Left (+)
and (–) speaker output terminals of the ampliﬁer to the corresponding (+) and (–)
terminals of the Left side speaker.

BRIDGED/MONO OPERATION
Note: For bridged/mono operation, we recommend that the minimum total
speaker load is no less than 4 ohms. (when two channels are bridged, each
channel will see half of the total speaker load)

Connect the left positive (+) speaker output of the ampliﬁer to the positive input
terminal of the speaker. Connect the right negative (“–”) speaker output of the
ampliﬁer to the negative input terminal of the speaker.

CAUTION: ANY DEVIATION FROM THE ABOVE SPEAKER CONNECTION
MAY CAUSE SERIOUS DAMAGE TO THE AMPLIFIER AND/OR SPEAKERS.
PLEASE DOUBLE CHECK THE CONNECTION BEFORE TURNING THE
SYSTEM ON.
