Connect the fuse holder as close to the vehicle
b as possible, using AWG 4 = 21 mm

or
heavier cable. Use ring crimp terminal cable to
connect to b. Apply silicon grease to the
fuse to prevent corrosion. Connect to ampl
inputs via a Fuse block. The amp terminals accept
16 mm

(AWG5) cable size
Be sure to use a rubber grommet or a plastic
insulating tube where the cable passes the firewall
or other places when it can easily be jammed.
Use wire ties to secure to existing cables in the
engine compartment.
Wiring
ULTIMATE TA2
Power terminals ( BATT+)
Ground Terminal ( GND )
Remote terminal
Connect the radio power antenna lead = remote turn
on/off from the car stereo to the amplifier remote
connection. This turns on the amplifier whenever
the car stereo is turned on.
We recommend to use a separate remote wire and
run the RCA lead separate from remote wire, power
cables and speaker cables.
You can insert the cable directly into the amplifier
terminal. If there is no remote voltage available from
the stereo, you must connect to the ignition key
through the radio or any accessories fuse.

Connect to a good chasis ground. The ground
connection should be clean, unpainted metal to prov-
ide 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.
Use only two 20
ampere ATC blade type
fuses. Make sure to
replace with the same
value.
The value is printed
above the fuse holders.
