INSTALLATION

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

wirewithin 18" of thebattery.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 main fuse or

circuitbreaker.Usea powerdistributionblockorfusenearyouramplifiers

with the appropriate fuse for each individual power wire.

BACK TO CONTENTS

The following is a basic formula to be used as a guide to determine current

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

™4400 amplifier has four channels at 50 watts

RMS per channel into 4 Ohms (50 x 4 = 200).You would use the

formula in the following way:

200W x 2 = 400W

400W = 33.3A Total current draw.

12V

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

doubleit's4OhmRMSrating.All

POWERCLASS

™amplifierswilleffectively

double their power at this load.

100W x 4 x 2 = 800W

800W = 66.6A Total current draw.

12V

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

Fuse must be

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 of the power

wire to avoid radiated noise.

Firmly attach Amp

Ground Wire to solid

metal (see page 6).

Avoid sharp edges that

could chafe through the

insulation.

Factory Ground wire may

need to be replaced if it is

frayed or broken.

For systems over 300 watts,

add a ground cable from the

amp to the battery

(see page 6).

WIRING

BACK TO CONTENTS

Grounding

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 area around

and underneath to be sure you won't drill into wires, brake or fuel lines.

Drill a pilot hole in the middle of this area.Terminate the ground wire

with a ring connector and attach 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.

If your grand total current draw is over 50 amps (or total output

power is over 300 watts), you should run a ground wire beside

your power wire from the battery to the amplifier(s) in addition

to your regular ground wire. Keep the ground and power wires

as close together as possible, and use the same gauge wire for both.

This will ensure that you have a good ground path, and may eliminate

such potential problems as engine noiseand overheated amplifiers.

Charging System Considerations

If your grand total current draw is over 100 amps (or total output

power is over 600 watts), you are probably exceeding the capability

of your charging system.Dimming lights and fluctuating voltage are

solid indicators that you need to upgrade your alternator, battery

(or go to multiple batteries), or both.

Keep in mind that your amplifiers simply convert electrical energy

to acoustical energy, and any electrical deficiency will compromise

the performance of your sound system.

For more information about charging system upgrades, see your

local authorized

POWER / GROUND

BACK TO CONTENTS

POWER / GROUND and REMOTE

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

PowerLock

power

and ground connector (supplied).With a small flat bladed screw

driver, loosen the screws before attempting to insert the cables.

Insert the wires into the appropriate hole, and tighten the

screws. Once the wires are secure, the

PowerLock

may be

plugged into the amplifier.The Power/Ground

PowerLock

will

accommodate 6 gauge wire for the

PC4200 / PC4400

, and 4 gauge

wire for the

PC4800

and

PC6600

Remote turn-on

Your head unit should have a lead marked 'remote' or 'power

antenna' which will be used to turn on your amplifier. Extend

this lead through your vehicle along with your RCA signal wires.

Strip 1/4 inch of insulation off the wire and insert the end into

the center terminal of the 5-pin speaker/remote

PowerLock.

BACK TO CONTENTS

Using 16 gauge or larger, run the speaker wires from the

amplifier location through the vehicle to the speakers.Observe

the same precautions for routing these wires that you followed

for running the power and remote turn-on wires.Cut off excess

and, using wire strippers, strip 1/4 inch of insulation. Locate

the speaker/remote turn-on

PowerLock

connector. Loosen the

four outer screws on the underside of the connector and insert

the front (

PC4200, PC4400

and

PC4800

) or sub (

)

speaker leads into the end.Check to be sure you've maintained

proper polarity before securing each wire.

Speaker/Remote

PowerLock

For the rear channels, locate the four terminal speaker

connector. (For PC650, the front channel also uses

a four terminal

PowerLock

connector.) On 4 and 6 channel

PowerClass Amplifiers, all speaker

PowerLocks

plug into the

amplifier with the screws facing up. Loosen the screws on the

top of the blocks and insert the stripped ends of the speaker

wires into the end. Double check polarity, secure each wire by

tightening the screws, and plug the

PowerLock

connector into

the amplifier with the screws on top.
