POWER CONNECTIONS:
GROUND - This is the high current ground connection to the chassis of the
car. It should be fastened to a clean ground connection in the vehicle, capable
of handling high current loads. This wire should be no longer than 3 feet (1
meter)
+12v - A high current line run direct from the batter is highly recommended to
insure adequate current and voltage. This line MUST be run through a
dedicated fuse of some kind and this fuse should be located immediately next
to the power source. This in-line fuse is used to protect the vehicle should a
short to chassis occur.
TRIGGER - This line tells the amp to turn on and is remotely switched from
the radio which normally provides an amp “trigger” output. This line is
required to go “high” (+12V) to turn on the amp. If this line is not available, use
the power antenna line trigger which is normally available in most radios.
FUSE - This fuse is only for catastrophic situations should the amplifier begin to
self-destruct or incur installation situations where gross amounts of current are
being required from the amp beyond its design limits. Although another fuse
should be installed inline with the high power line at the battery, this amplifier
mounted fuse MUST remain in the circuit to protect the amplifier.
SPEAKER OUTPUTS - The amplifier is connected to appropriate impedance
speakers via these leads. It is IMPERATIVE that these leads NOT be
connected or touch the vehicle chassis in any way or the amplifier will be
damaged. The (+) and (-) leads of the amp are in no way inter-connected to
one another. Also, NONE of the leads can touch each other, touch ground, or
touch +12V or damage may occur to the amp or vehicle.
REMOTE GAIN CONTROL - This amplifier is provided with internal circuitry that
allows for a remote gain control to adjust the bass output level depending
upon the listener’s choice. ONLY the supplied gain control can be used with
the amp or the circuitry for it to be used properly.
CAUTION!! Unfortunately you CANNOT use simple telephone “Y” connectors
to daisy chain to multiple amps in hopes of controlling the gains of multiple
amps.
LINE LEVEL INPUTS - The most commonly used inputs in the aftermarket world
are RCA type line level inputs. These inputs can handle up to about 6 Volts
rms without overdriving the amplifier. Such high voltages are rarely found from
car audio head units so this is a very comfortable value. But, should the use
need to drive the amp directly from speaker level leads, use the supplied “High
Level Adapter” to connect to the amp.
LINE LEVEL LOOP-THRU - These connectors are simply hard wired to the other
inputs and do not loop-through the crossovers in any way. If you wish to
“daisy-chain” multiple amps simply connect them to the “loop-thru” leads.

electrical connection.
Connect the radio power antenna lead from
the receiver to the amplifier terminal.
This turns the amplifier on whenever the
receiver is turned on.
