5. AMPLIFIER MOUNTING
Attention! For your own safety, disconnect the positive battery terminal (+12V) or remove the main fuse
in the positive power cable near the car battery, before you start any wiring work!
Once the location where the amplifier will be mounted is defined, use the unit as a template for the
marking of the mounting holes with pencil or felt-tip marker. The mounting holes should be pilot-dril-
led, using a 2,5mm or 3mm drill bit.
Now secure the amplifier in its position by tightening the screws evenly and re-check proper fit after
completion.
Important! Never allow the heatsink of the amp to come in contact with metal surfaces of the vehicle.
The resulting ground-loop can result in a loud hum!
6. CABLE ROUTING
RCA INTERCONNECTS AND REMOTE WIRING
Carefully run the audio signal interconnects, the remote lead and the cable of the remote low pass level
boost unit (EA2500D & EA475-350D) from the head-unit or dashboard to the amplifier. As mentioned
before, the audio signal cables should be routed separately from the power cables. Connect the remo-
te (turn on/turn off) lead to the respective input terminal of the amplifier and to the remote output of
your head-unit. Now you can connect the RCA interconnects to the respective outputs of your head-
unit and to the inputs of the amplifier. Pay attention to connect the stereo interconnects correspondin-
gly, left is 1CH, right is always 2CH.
If you want to drive a subwoofer system with your amplifier and use the lowpass level remote, you must
find a good location to mount the remote control unit first. Fix the remote in place by using the self tap-
ping screws and connect the remote wire to the remote device and the amplifier.
Note: The EA2500D features one pair RCA line inputs, and another pair of RCA line-outputs. The RCA
line outs are used to daisy chain the RCA input signal, for example if two or more EA2500D are inten-
ded to be driven by one RCA line-out signal from the head-unit.
LOUDSPEAKER WIRE ROUTING
Once the speaker cables have been routed, turn loose the screws of the speaker terminal binding posts
and – after inserting the stripped speaker cables – re-tighten the screws. Always maintain correct pola-
rity („
“ to „ “; „ ” to „ ”).
