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 Speaker, use heavy gauge speaker cable
for these connections (14AWG recommended minimum).
We recommend that the minimum total impedance of the speaker load is no
less than 2 ohm. The amplifier has 2 each (+) terminals and 2 each (-) terminals.
These terminals are duplicates, meaning you can use any combination of + and
– connections for a single speaker (Model 300.1 only). Connect the positive
(+) speaker output of the amplifier to the positive (+) terminal of the speaker.
Connect the negative (-) speaker output of the amplifier to the negative (-)
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.
