POWER WIRING AND SIGNAL CONNECTIONS
Your DLS DD amplifier requires unrestricted current to deliver peak performance, so do not “starve”
your amplifier by using small power cable. Using under sized power cable can result in unnecessary over-heating of the amplifier,
distortion at high volume levels and might even cause the thermal protection circuitry to shut off the amplifier.
Remember, bigger wire is better!
•
Use rubber grommets when running cables through any metal or sharp plastic, to prevent accidental shorting or shearing.
Make sure the cables do not interfere with normal operation of the vehicle.
•
The audio signal cables (RCA interconnects) should be kept far away from any potential sources of electrical interference
such as electronic vehicle management systems (relays, engine computers etc.), wiring harnesses, fuel pumps etc
.
Fig.4 Power Input Connection
These amplifiers are designed to work within a 10 to 16 volt DC range. Before any wires are connected, the vehicles electrical
system should be checked for correct voltage supply with the help of a voltmeter.
First, check the voltage at the battery with the ignition in the OFF position. The voltmeter should read no less than 12v. If your
vehicles electrical system is not up to these specifications, we recommend having it checked by an auto electrician before any
further installation. Once the vehicle is checked, make certain the correct cable gauge is used. The DD amplifier terminals are
capable of accepting up to 8 gauge power and ground
cable. We recommend using as large a gauge cable as possible, use the Power Cable Selection Chart to cal culate the
correct power wire size for your application.
*** WARNING ***
Disconnect the negative (-) battery terminal before you start any wiring
work! The battery of your car audio system must be disconnected until the
entire wiring installation is completed.
