INSTALLATION

You will need to install an in-line fuse or circuit breaker in

the power wire within 18" of the battery.This fuse or circuit

breaker is to protect your vehicle from fire in case the power

wire shorts to the vehicle body. If you are only using one

amplifier, use the fuse rating indicated in this chart. If you are

using more than one amplifier, add up the fuse ratings for all the

amplifiers.This sum is the rating for your fuse or circuit breaker.

You may also want to add a power distribution block near your

amplifiers to keep the wiring tidy.

Thefollowingisa basic formulatobeusedasa guide todetermineamperage

draw. A 50% amplifier efficiency rating is used as an average.Your new

POWERCLASS

™amplifier is more efficient, other amplifiers will probably

be less. This formula is to be used as a guideline. Using wire of a larger

gauge can only improve the current transfer of your system. Do not use

smaller gauge wire.

Total RMS output x 2 = Total Input Wattage

Total Input Wattage = Current Draw (in Amps)

Supply Voltage

Example:A

POWERCLASS

™2200 amplifier has two channels at 50 watts

per channel RMS rating into 4 Ohms (50 + 50 = 100).You would use the

formula in the following way:

100W x 2 = 200W

200W = 16.7A Total amperage draw.

12V

If the same amplifier is driven into a 2 Ohm stereo or 4 Ohm mono load,

double its4Ohm RMSrating.All

POWERCLASS

™amplifierswill effectively

double their power at this load.

100W x 2 x 2 = 400W

400W = 33.3A Total amperage draw.

12V

If you are using more than one amplifier, add up the total amperage draw

for all of them and choose the appropriate gauge based on the grand total.

WIRING

BACK TO CONTENTS

Before beginning, disconnect the negative (-) terminal of the

battery prior to working on the positive (+) terminal to prevent

a short to ground.This is important, unless you want to spend

the rest of your life with a nickname like

"Sparky,"

"Smokey."

Reconnect the negative terminal only after all connections have

been made.

Warning!

Fuse must be installed within 18" of battery

Drill a hole in the firewall

and 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 you replace the trim.

Run signal cables (RCAs)

and remote turn-on lead

down the opposite side of

the vehicle from the power

wire to avoid radiated noise.

Firmly attach Amp

metal (see page 5).

Avoid sharp edges that

Designed and Handcrafted in the U.S.A.

Locate an area near the amplifier(s) that is metal and clean an

area about the size of a quarter to bare metal. Inspect the

areaaroundandunderneathtobesureyouwon'tdrillintowires,

brake or fuel lines, etc.Drill a pilot hole into the middle of this

area.Terminatethegroundwirewitha ringconnectorandattach

it to the bare metal using a #8 sheet metal screw and washer

or preferably, a bolt, nut and a star washer (not supplied).We

suggest crimping and soldering this connection. After the

connection is complete, coat the area (on both sides) with

silicone or some similar material to prevent rust from

developing on the bare metal.

POWER / GROUND

PowerLock

Once you have run both the power and ground wires, it's time

to connect the cables to the amplifier.Cut off excess wire and,

using wire strippers, strip the ends of the power and ground

cables approximately 1/4 inch. Locate the

Insert the wires into the appropriate hole, and tighten the

(4V up to 12V).

RCA OUTPUTS

Left and Right RCA

outputs provide either

high or low pass signal to

another amplifier. This

signal will be low pass if

you've selected high pass

for the speaker outputs,

and vice versa.

BACK TO CONTENTS

There are two sets of RCA jacks on the front end of your

amplifier.The RCA cables from your head unit go in the set

labeled INPUTS. If your head unit doesn't have RCA outputs

don't worry. Simply add a set of RCA plugs (available at your

dealer) to your front or rear set of speaker leads (see drawing

below), plug them into the input jacks, and push in the INPUT

ATTENUATION button.

Balanced Differential Inputs

This circuitry is capable of eliminating noise radiated into your

signal cables by up to 40dB.This is equivalent to a noise

reduction of approximately one hundred times what the noise

level would be without this circuitry.It provides all the benefits

of a true 'balanced' line without the need of any special cables

(see diagram below).This type of input works with any

conventional RCA cable.
