Wiring Instructions; Ground Connection; Speaker Connections - Cerwin-Vega STEALTH SX220.2 Owner's Manual

WIRING INSTRUCTIONS

Power Connection
The main power cable must be connected to the positive terminal of the vehicle battery to provide
an adequate voltage source and minimize noise. There must be an inline fuse within 18 inches of the
battery. Connecting the battery terminal lead to any other point will reduce the power output and
may cause noise and distortion. Use only 4 gauge or larger wire for this lead and connect it to the (+)
terminal of the battery with system fuse inline. Do not install the fuse in the fuse holder until the
entire installation is completed.

Ground Connection

The ground terminal (GND) connection is also critical to the correct operation of the amplifi er. Use a
wire of the same gauge as the power connection and connect it between the ground terminal (GND)
of the amplifi er and a metal part of the vehicle close to the mounting location. This wire should be
as short as possible and any paint or rust at the grounding point should be scraped away to provide a
clean metal surface to which the end of the ground wire can be screwed or bolted.
Remote Turn-On Connection
The amplifi er is turned on by applying +12V to the remote turn-on terminal (REM). The wire lead to
this terminal should be connected to the remote lead from the car stereo which will provide the +12V
only when the car stereo is turned on. If the car stereo does not provide a remote lead, the remote
turn-on lead may be wired to an accessory terminal in the car's fuse block. This will turn the amplifi er
on and off with the ignition key, regardless of whether the car stereo is on or off.

Speaker Connections

Depending on the type and number of speakers used with the amplifi er, wire them to the speaker
terminals as per the appropriate wiring diagram (see below). For most applications 18 gauge wire is
adequate for the speaker leads. For leads in excess of ten feet, 16 gauge wire is recommended. When
wiring the speakers, pay careful attention to the polarity of the terminals on the speakers and make
certain they correspond to the polarity on the amplifi er. Do not ground any speaker leads to the chassis
of the vehicle. Please see your authorized Cerwin-Vega Mobile dealer for specifi c wire recommendations.
TYPICAL SPEAKER CONNECTIONS TO YOUR CERWIN-VEGA MOBILE AMPLIFIER
Most aftermarket source units will provide you with at least one pair of RCA outputs to provide a
clean (low-level) input for your amplifi er.
