4 CHANNEL POWER AMP OWNERS MANUAL
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 verifi ed 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 man-
ner not outlined in the manual will void your warranty and may possibly cause damage to the vehicle and/or the
amplifi er.
Warning: The battery ground should remain DISCONNECTED at all stages
of installation.
LOCATION/MOUNTING
When selecting a location to mount your amplifi er, please keep in mind that electronics are sensitive to vibration, moisture, and
heat. Make sure the amplifi er 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 amplifi er 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 dam-
age over time. Using the amplifi er 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 the
gas tank, wires, etc…).
Remove the amplifi er and pre-drill the locations for the screws/bolts that you have selected that fi t the amplifi er and your new
installation purposes. Permanently mount the amplifi er to the selected location.
(Figure 3. shows a typical system confi guration).
Note: It is best to mount the amplifi er to some form of insulating surface, such as MDF, so that the chassis of the amplifi er
does not come in contact with the vehicle chassis (if a single screw makes contact with both the amplifi er and vehicle chassis,
it is not insulated). This will reduce the possibility of any ground related noises and will shield minor amounts of
radiated noises.
