Before cutting or drilling,
make sure the amplifier will physically fit in its desired location.
Check for clearance around rear deck torsion bars or other structural
elements.
Everything should fit
Before using any tools or
moving vehicle components, take five minutes to review the installation
intentions.
A good connection
When making connections, make
sure each connection is clean and properly secured. Observe all polarity
markings carefully to ensure proper end performance.
:: When Working ::
To make a good connection
The ground wire (-) should run
from the amp directly to the chassis (metal) of the car. Make sure that
you scrape away the paint to make a good connection
Earth connections
Earth connections are very
important, as a bad earth will cause noise and interference. Earth leads
should be firmly fixed to a major part of the vehicle chassis,
preferably the floor or firewall. If alternator whine is evident, all
earth wires should be connected together and at the same earth point.
