Battery And Charging; Wiring The System - Eton MA 750.1 Installation & Operation Manual

Installation
Passenger Compartment Mounting
Mounting the amplifier in the passenger compartment will work as long as you provide a sufficient amount of air
for the amplifier to cool itself. If you are going to mount the amplifier under the seat of the vehicle, you must have
at least 1" (2.54cm) of air gap around the amplifier's heatsink.
Mounting the amplifier with less than 1" (2.54cm) of air gap around the amplifier's heatsink in the passenger
compartment will not provide proper cooling and will severely affect the performance of the amplifier and is
strongly not recommended.

BATTERY AND CHARGING

Amplifiers will put an increased load on the vehicle's battery and charging system. We recommend checking
your alternator and battery condition to ensure that the electrical system has enough capacity to handle the
increased load of your stereo system. Stock electrical systems which are in good condition should be able to
handle the extra load of any ETON amplifier without problems, although battery and alternator life can be
reduced slightly.To maximize the performance of your amplifier, we suggest the use of a heavy duty battery and
an energy storage capacitor.

WIRING THE SYSTEM

CAUTION
authorized Eton Dealer for installation.
CAUTION
the unit, fire and/or possible injury.
CAUTION
sensitive equipment or harnesses.The power wires carry substantial current and could induce noise
into the audio system.
1. Plan the wire routing. Keep RCA cables close together but isolated from the amplifier's power cables and any
high power auto accessories, especially electric motors. This is done to prevent coupling the noise from
radiated electrical fields into the audio signal.When feeding the wires through the firewall or any metal barrier,
protect them with plastic or rubber grommets to prevent short circuits. Leave the wires long at this point to
adjust for a precise fit at a later time.
NOTE:
We recommend to use power cable 4 AWG for + and - battery wiring
2. Prepare the RED wire (power cable) for attachment to the amplifier by stripping 3/8" of insulation from the end
of the wire. Insert the bared wire into the B+ terminal and tighten the set screw to secure the cable in place.
NOTE:
The B+ cable MUST be fused 18" or less from the vehicle's battery. Install the fuseholder under
the hood and ensure connections are water tight.
3. Trim the RED wire (power cable) within 18" of the battery and splice in a inline fuse holder (not supplied). See
Specifications for the rating of the fuse to be used. DO NOT install the fuse at this time.
4. Strip 1/2" from the battery end of the power cable and crimp an appropriate size ring terminal to the cable. Use
the ring terminal to connect to the battery positive terminal.
5. Prepare the BLACK wire (Ground cable) for attachment to the amplifier by stripping 5/8" of insulation from the
end of the wire. Insert the bare wire into the GROUND terminal and tighten the set screw to secure the cable in
place. Prepare the chassis ground by scraping any paint from the metal surface and thoroughly clean the area
of all dirt and grease. Strip the other end of the wire and attach a ring connector. Fasten the cable to the chassis
using a non-anodized screw and a star washer.
NOTE:
Keep the length of the BLACK wire (Ground) as short as possible. Always less than 30"(76.2cm).
6. Prepare the Remote turn-on wire for attachment to the amplifier by stripping 5/8" of insulation from the end
of the wire. Insert the bared wire into the REMOTE terminal and tighten the set screw to secure the wire in
place. Connect the other end of the Remote wire to a switched 12 volt positive source. The switched voltage is
usually taken from the source unit's remote amp on lead. If the source unit does not have this output available,
the recommended solution is to wire a mechanical switch in line with a 12 volt source to activate the amplifier.
