PC2400, PC2600

amplifiers, we've

taken bass control to a higher level with

BASS PLUS

™

The two

BASS

switches (labeled 1 and 2) on the front

end of the amplifier allow you to select one of four

frequency centers - 30Hz, 36Hz, 44Hz and 60Hz.The Q

SELECT switch determines the width of boosted

frequencies. A 'Q' of 2 (switch out) will give you a wide

boost while a 'Q' of 4 will boost a narrow range of

frequencies (See chart below). On the rear end panel

you will find the

BASS

™

level control and the plug-in for

an optional

BASS REMOTE

™

dash mounted level

control. Adjust the level control clockwise for up to 18dB

of boost at your selected frequency and Q.

Optional

This boost control can be mounted in the

dash and will supersede the boost

control on the endplate.

Optional

Tools/Parts needed for Installation (not supplied)

Small flat blade screwdriver

Phillips Screwdriver (#2 or medium sized)

Wire cutters

Wire strippers

4 - #6 round head screws, and 1 - #8 sheet metal screw

(or nut, bolt, and star washer)

2 - Ring connectors (large enough to accommodate your

method of grounding)

In-line fuse or circuit breaker - see fuse chart below

Power and ground wire - see Power Wire Calculator on page 3

Speaker wire - 16 gauge or larger

Grommets (sized to work with the power wire you plan to use

in your installation)

Tube of silicone sealant

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.

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

™2600amplifierhas twochannelsat 150watts

per channel RMS rating into 4 Ohms (150 x 2 = 300).You would use the

formula in the following way:

300W x 2 = 600W

600W = 50A Total current draw.

12V

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

doubleit's 4OhmRMS rating.All

POWERCLASS

™amplifierswilleffectively

double their power at this load.

300W x 2 x 2 = 1200W

1200W = 100A 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.

NOTE: The ground wire should be the same gauge as the power wire.

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

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

areaaroundandunderneathtobesureyouwon'tdrillintowires,

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

area.Terminatethegroundwirewitharingconnectorandattach

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 noise

and overheated amplifiers.

Charging System Considerations

Ifyourgrandtotal currentdrawisover 100amps(or totaloutput

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

capability of your charging system. Dimming lights and

fluctuatingvoltageare solid indicatorsthatyouneed 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 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

Insert the wires into the appropriate hole, and tighten the

screws.Once the wires are secure, the
