PASSENGER MOUNTING

Under the seat or floor mounting will work as long as there is a
minimum of 1” (2.5 cm) of air gap above the amplifier heatsink.
Vertical mounting of the amplifier is still the best.
Caution! Be sure to avoid running the power wires near the low
level input cables, antenna, sensitive equipment or harnesses. The
power wires carry substantial currents and could induce noise.
1. Power – The gold B+ terminal must be connected

directly

to the
positive (+) terminal of the battery with an appropriate size wire.
(See the Specifications for more information.) This provides a
power source with a low voltage drop and low noise.
Be sure to use the supplied fuse and fuseholder within 18”
(45.7cm) of the battery’s positive terminal. Failure to do so may
cause damage to the vehicle and the amplifier.
WIRING THE SERIES 1
Note: You will need to cut the wire loop that
is attached to the fuse holder in half and
splice the fuse into the power line using
appropriate in-line butt connectors.
If the power wire must be extended beyond
17’ (518.16 cm), we recommend the use of 10
gauge stranded wire.

2. Ground – The GND terminal grounds the amplifier and is
connected to the chassis of the vehicle. When grounding, scrape
paint off metal to ensure a good, clean ground connection. To
prevent ground loops, we recommend you refrain from extending
the ground wire beyond 18” (45.72 cm) in any installation.
3. Remote Turn-On – The Series 1 amplifiers are turned on by
supplying positive (+) 12 volts to the AP terminal. Usually the
terminal is connected to the source unit’s “Accessory” or “Auto
Antenna” lead, either of which will go to +12 volts when the
source unit is activated.
Although the majority of high quality automotive source units
have an Accessory or Antenna output, there may be exceptions.
If the source unit has no Auto Antenna lead (or if the Auto Antenna
goes down during tape/CD operation), we recommend a switch
in the car with one terminal connected to +12 volts and the other
to the Series 1 AP lead. This will allow you to engage the amplifier
manually.
