Tools and materials needed
Tools:
Flat and Phillips screwdrivers
Wire cutter
Wire stripper
Electric drill with drill bits
Crimping tool
Digital multimeter or test lamp
Wire brush, scraper or a piece
of an abrasive sheet to remove
paint for a good ground connection
Grease to protect the ground
connection from oxidation
Material:
Speaker wire: minimum
12 AWG = 4 mm
nected to S1
13 – 16 AWG = 1,5 - 2,5 mm
speakers
Sheet metal screws for mounting the
amplifier to the amplifier board and the
amplifier board to the car + some extra
for fuse holder, amplifier ground etc.
Electrical insulation tape
½ inch thick plywood or particle board
for the amplifier to be mounted upon.
Amplifier installation kit:
If available, buy an amplifier installation kit. It con-
tains normally all you need. This is what you have
to buy if you buy the items separately
20- 25 feet = 6-7.5 meter power cable,
minimum AWG 8 = 10 mm
1 pc of fuseholder to install close to the
car battery + fuse (see below)
20 feet of AWG 15 = 1,5 mm
remote turn on / off cable from radio.
RCA-cable for input from radio.
- 20 feet or 5 meter for trunk installa-
tions
-12 feet or 2 – 3 meter for under seat
installations
Two ring crimp terminals, –one
for connection to the battery plus and
one for the amplifier ground connec-
tion.
Four to eight splicers to connect spea-
ker cables to high level input cable, if
high level input is used.
Wire ties
Insulating grommet or insulating tube
Fuses
There are no internal fuses in the amplifiers. The
use of an external fuse is essential for safety.
Recommended fuse rating:
Signature 2:
Signature 4:
Signature 1:
NOTE!
Max fuse value is always related to cable size.

Power wiring
Power terminal ( +12V)
Connect the fuse holder as close to the vehicle
battery+ as possible, using 4 AWG /20mm
8 AWG/10mm
power cable. Use a ring crimp
2
terminal to connect to battery. The 4 AWG/20mm
cable can use a 100 Amp fuse , if the cable is
smaller, the fuse value must be lower (see table
on previous page). This fuse is to protect from
cable fire!
Be sure to use a rubber grommet or a plastic insu-
lating tube where the cable passes the firewall or
other places where it can be easily jammed.
Use wire ties to secure to existing cables in the
engine compartment.
Ground Terminal ( GND )
Connect to a good chassis ground. The ground
connection should be clean, unpainted metal to
provide a good electrical connection. Use a wire
brush, a scraper or a piece of an abrasive sheet
to clean the metal. Use a lock washer or two to
secure contact. Protect with silicon grease or by
paint applied afterwards.
Power Light / Protect light
The power indicator (blue) is lit when the
amplifier is turned on.
Power
The protect indicator (red) is lit when the
(Blue)
amplifier shuts down from over-heating,
Protect
or a short circuit (speaker failure).
(Red)
Turn off your audio system to reset the
amplifier if the red protect light is turned
on. If the red lamp doesn't turn off, con-
tact your local dealer for advice.
