AMPLIFIER MOUNTING

Attention! For your own safety, disconnect the negative battery terminal from
the ground of your vehicle - or else, remove the main fuse of the 12V power
cable, before you start any wiring work!
Use the amp itself as a template to mark the mounting holes with a pencil or a felt-
tip marker. Pilot-drill the holes, using a 2,5mm or 3mm drill bit on your power drill.
Insert the supplied rubber washers into the mounting holes of the amp. A car-ampli-
fier must always be mounted isolated from the vehicle's chassis ground! Bolt the
unit in place with the supplied self tapping screws.
Note! The amplifier, or parts of it, must never touch or have contact with metal
parts of the vehicle, since electrical ground-loops always result in loud hum
noise!

CABLE ROUTING

RCA INTERCONNECTS AND REMOTE WIRING
Run the RCA interconnects and the remote lead from the head-unit to the amplifier.
Note that RCA interconnects must be routed completely separate from the main
power cable. Connect the remote (turn on/turn off) lead to the REM input terminal
of the amplifier and to the remote output lead of your head-unit. Now you can plug
in the RCA interconnects to the line outputs of your head-unit and to the RCA
inputs of the amplifier.
LOUDSPEAKER WIRE ROUTING
Strip the ends of the speaker wires and turn loose the speaker terminal screws.
After inserting the stripped speaker cables – re-tighten the screws. Be sure to main-
tain correct polarity („ " to „ "; „ „ to „ „).
MAIN POWER CABLES
Run the positive main power cable („+12 V") directly from the positive terminal of
the car battery to the amplifier. For protection of your car audio system against
electrical short cuts and fire hazards, you must insert a fuse holder within the first
30cm of the positive main power cable. The applicable fuse value must be matched
to the current (A) limitations of your main power cable cross section!
Connect the ground cable to the ground terminal input of your amplifier and to a
grease and rust free ground point in your vehicle. Keep the ground cable („-12V")
as short as possible. The ground power cable must have the same cross-section
as the positive power cable.
Tighten up both power input terminals, and double check for tight fit of both main
power cable leads!
Reinsert the main fuse, or re-connect the ground clamp lead to the negative pole of
your battery.
When turning on the headunit, the LED of your SPECTRON amp should light up
green. If the LED lights up red, something is wrong and you have to double-check
and verify all previously described installation steps once more!
