Installation
Before installing any audio equipment, it is good practice to disconnect the ground
terminal on the battery to avoid damage
to the vehicle or audio equipment. Failure to do this means you’re a few brews short
of a 6-pack and you probably
already acquired the nickname of “Sparky” or “Smokey”. Not cool! Do NOT hook the
ground cable back up to the battery
until the rest of the wiring is complete.
Factory ground wire may
need to be upgraded, especially
if it is smaller than the
power wire, frayed, or broken.
Positive
battery
terminal
Fuse must be
installed within
18” of battery.
Drill a hole in the firewall &
use a rubber grommet to
keep wire from shorting.
Run the cables under the
carpet near the side of the
vehicle. Be careful not to
drill or screw into the
wires when replacing trim.
Ground cable to
bare metal chassis/
frame with nut &
bolt. No screws or
seat/seatbelt bolts!
Run signal cables (RCA)
and remote turn-on lead
down the opposite side of
the vehicle of the power
wire to avoid radiated noise.
Avoid sharp edges
that could chafe
through the insulation.

Control Definitions
Alrighty, here comes the fun stuff. We’re going to break this down to it simplest form so that there
is no way you can possibly do any damage in the installation process to your audio system.
We’re going to explain in detail how every single knob and switch work rather than turn you loose
on a sophisticated amplifier and have problems. READ EVERYTHING!
Trust us, it’ll be worth it… Before you do anything, undo the ground cable from the battery.
Power Terminal Block
GND – This is the Ground connection. Bolt the Ground cable to a bare metal part of the chassis/
frame. Do NOT us self-tapping screws or seat/seatbelt bolts!
+12V – This is the Power Connection. This cable gets connected directly to the battery. You MUST
use a fuse holder or circuit breaker within 18” of the battery. All cables ran through the firewall
must be protected by a rubber or plastic grommet. If you have multiple amplifiers, the main fuse
or circuit breaker at the battery should be the sum of all fuses or slightly less.
REM – This is the remote Turn-On connection. Connect to the amplifier output or power antenna
output of the source unit. If the unit does not have a switched +12V output, you can use another
switchable +12V.
Speaker Terminal Block
This is the Speaker(s) Connection. All components, coaxials and subwoofers connect here.
Crossovers
These controls allow you to pass and block frequencies to each driver. This is one of the most
important parts of tuning any audio system.
LOW PASS – This control allows you to pass only frequencies lower than the frequency you choose
to the drivers. For example, if you are powering a sub woofer and you choose 70Hz, then only
70Hz and lower tones will be passed through to the subs while all unwanted higher frequencies
above 70Hz will be blocked.
HIGH PASS - This control allows you to pass only frequencies higher than the frequency you
choose to the drivers.
High Pass crossover filters below 50Hz are also considered “subsonic” filters.
Multiplier Switches – Sometimes you may need a range that is not within the range supplied
by the control potentiometer. In this case, if the amplifier has a multiplier switch, the range can
change to accommodate your needs. For example, let’s say you have a 4 channel amplifier
and you want to put the tweeters (1”) on the front channels and the midbass (6.5”) on the rear
channels, and use all electronic crossovers. You can set the High Pass for the tweeters at 4kHz.
The low pass, if it as two ranges, may be from 50-800Hz which is not high enough. By using the
multiplier switch, that same control can change the range from 50Hz-800Hz to 250Hz-4kHz. If this
doesn’t make sense and you do not understand frequencies clearly, PLEASE TAKE YOUR AMP TO A
PROFESSIONAL PRECISION POWER DEALER!
Bass EQ – This circuit allows you to choose a frequency between 30Hz and 90Hz and boost that
frequency by 0-12dB.
