Spec al Note on Z-150.6 SP Ampl f er

Please use caution when connecting speakers to channel 5. Because o the layout o the Z-150.6 SP

the positive and negative terminals o channel 5 are reversed rom the rest. We ind that some units

le t the actory with the terminal colors wrong on CH5. The printing on the amp is correct but still it

can be con using when the colors are di erent. We have corrected this but please check you Z-150.6

SP and note the correct positions as below.

A new standard n Sound Qual ty

Congratulations, on the purchase o your new Zapco Z-Series SP ampli ier.

We believe you now have the inest sound available in a car sound ampli ier, and

we think you should know a little bit about what makes this amp unique in a

world o so many so-so products.

The b rth of the Zapco SP ampl f ers

In 2012 Zapco introduced the new Z-Series o SQ amps. These amps were not

conceived so much by our engineers, as by input rom audiophiles and car

sound anatics around the world. Starting about 2004, at Zapco training

seminars in Asia and in the EU, we began running into audiophiles who were

changing certain internal components in our ampli iers to achieve what they

elt was better quality sound.

With that in our minds, we developed the Z-Series amps with less measuring

and more listening. So or the Z-Series o Zapco ampli iers, we experimented

with internal components and new circuits to see i we could take our amps to

the next level o sound quality by investing in di erent internal components

and circuit designs.

The resulting Z-series and eventually the Z-series LX amps were the results o

this unique development method. These amps have been virtually unbeatable

on the Car Sound Competition circuit.

But ampli iers designed solely or sound quality run warm, and on "the street",

cruising the boulevard, or at the park with the doors open and the system

cranked ull on, these amps could be driven into protection.

How do we get Z-Series sound in an ampli ier or ull-on, ull-time cranking?

We couldn't! It wouldn't work without a much bigger chassis or a sacri ice in

sound quality. So we had to ind a new way to build the amps.

And we did! The Z-150.2 SP and Z-400.2 SP stereo amps, Z-150.4 SP

4-Channel amp and the 6-Channel Z-150.6 SP are the Zapco SP, or Super

Power, ampli iers.

To reach our goals we irst developed a new orced air cooling system in a chassis

with internal heat sink ins and ans to blow the heat o the chassis. Fans blow

on to the ins to move air down the chassis, and the side vents down the side

create turbulence that sends hot air out and cold air in along the whole length

o the amp.

This got us hal way there. Then we ound a new space-age material, to insulate

the output transistors, that can pull heat o devices much aster than the

standard insulators. So now we could trans er the heat rom the devices to the

chassis aster then pull the heat o the chassis aster.

The result: We now had an ampli ier that you can crank up to ull volume and

play that way all day long. And, with a ew upgrades in circuitry that we made,

you also get:

• High Pass, Low Pass, and Band Pass crossovers

• x10 Range Switch or accurate crossover requency selection

• Variable Sub Sonic ilter using the band pass

• Variable Bass Boost

• Variable Gain

• Auxiliary RCA Output

• Available Dash Remote

In most ampli iers all these preamp controls give you more versatility but they

also rob you o signal quality. But in the Zapco Z-Series SP amps, even with

crossovers and bass boost you get over 103dB signal to noise ratio, less than

0.1% THD, and greater than 60dB channel separation. And the SP amps get a

10% power gain rom increased thermal e iciency that reduces the "de-rating"

o the output devices.

A quick rundown o the SP amp's unique eatures:

• Cooling ans with thermal speed control

• Insulator with 70% less thermal resistance o MICA or aster heat trans er

• Proprietary RCA connectors with extra heavy plating soldered directly on

the PCB (Zapco design) with 6 ground lugs on each, or an absolutely

secure mount

• Balanced and di erential inputs with one tenth the normal resistance

• New Op-amp with lower noise than even the current LX amps

• Bass Boost that is out o the circuit when set to 0

• Capacitors with lower internal resistance and lower inductance (only just

now appearing in the LX amps)

• Fine adjustment or bias in each channel

• A custom plaque with model and serial number lets them know this amp

is special

• And new stronger packaging so this unique ampli ier can be shipped

with con idence

We sincerely hope you enjoy your new Z-Series SP ampli ier as much as we

enjoyed the time we spent developing it.

Before you start your nstallat on

ZAPCO highly recommends that a use or circuit breaker be placed within 18"

o the battery. Although you will add a use or use block near the ampli ier it

is still a possibility that a pinched power wire between the component use

and the battery could result in a short, or even a ire. The protection device

should be placed where it can be accessed easily and all wiring should be

routed sa ely and correctly according to the ollowing guidelines:

Do not run wiring close to hot or spinning objects.

Always use wire grommets when routing wire through the irewall or any

other metal panels.

Make sure that the potential or pinched wiring is avoided by routing all wires

away rom moving hinges and seats. This also includes brake, gas and clutch

pedals, hood and trunk hinges, etc.

Continuous exposure to excessive sound pressure levels may cause permanent

hearing loss. ZAPCO strongly advises that you use common sense when setting

volume levels. I you experience ringing in the ears, it could cause permanent

hearing damage!

When connecting our ampli iers to pre-wired stock speakers, care must be

taken that there are no common connections between le t and right speaker

wires, i.e. two or more speakers using the same ground connection (very

common in pre-85 cars), as this will cause the ampli ier to go into immediate

protection or may cause damage to the ampli ier. Output connections are not

common chassis ground. Please ollow the hookup instructions in this owner's

manual. Any questions should be directed to your local ZAPCO dealer.

Plann ng your power connect ons

The power end plates o the Zapco SP ampli iers carry the power connections

and the speaker connections and vary somewhat by the number o channels.

For example, the power end o the Z-150.6 SP below has (o course) speaker

connections or six channels. One model, the Z-150.2 SP has on-board uses, while

all other models will require and in-line use with a rating as in the speci ications

page at the end o this manual. That said, the main 12-volt power input, the 12-

volt turn-on wire, and the main Ground connections are common to all models.

• The gold connection at the interior o the end plate is the main power

input. This must be connected the vehicle battery's positive (+) terminal,

and a main system use should be placed close to the battery.

• The silver connection at the outside o the end plate is the main ground

or negative connection. This must be securely attached to bare metal at

the vehicle rame, or other heavy chassis component with a direct

connection to the rame.

Note: Seat bolts and seat belt bolts are NOT good ground po nts

• The small terminal between the main power and ground is the +12

turn-on input and can be connected to the head unit turn-on output wire.

I none is available it can be connected to an accessory (ACC) terminal.

You should avoid using any ignition-on (IGN) wire, as they can be noisy.

Note: The Z-Ser es SP ampl f ers have term nals that do not requ re connectors. You s mply

nsert a bare port on of w re and t ghten the connect on w th the suppl ed Hex tool. As the w re

conforms to the connector the connect on can loosen. You should re-t ghten the connect on

after about a week.

Some words about Power and Ground

Note: The second most common cause of underperform ng ampl f ers s nsuff c ent power

current or a pour power connect on. The most common cause of underperform ng ampl f ers s

nsuff c ent ground current or a bad ground connect on.

12-volt current: Battery Power works only i it travels in a complete circuit rom

the battery positive terminal to the battery negative terminal. Main power

input, o course, is attached to the battery positive terminal. Ground current is

returned to the battery through the chassis to the to the point where the battery

is grounded.

The current available or your ampli ier to use to produce power will be

restricted by the smallest gauge o wire in the circuit and by the weakest physical

connection in the circuit.

W re S ze

It's o ten surprising how many people will obsess about signal wire but routinely

provide the ampli ier with only a raction o the current it needs to do its job.

The most common wire gauge used in car audio is 10-gauge, and the most

common location or ampli iers is in the trunk.

W re S z ng Chart

4 t 7 t 10 t 13 t 16 t 19 t 22 t 28 t

0-20 amps 14 12 12 10 10 888

20-35 amps 12 10 886664

35-50 amps 10 8866444

50-60 amps 88644442

65-85 amps 66442220

85 -105amps 66422220

105-125 amps 44422000

125-150 amps 22220000

Let's look at a airly small system. I you use a 50 watt/ch amp (25 amps)

or the highs and a 100 watt/ch amp (40 amps) or the woo ers, you need at

least a 4-gauge and maybe a 2-Guage wire to provide 65 amps at the trunk.

Anything less and your car won't go boom. It'll just go Blap!

Length of Run

Note: It takes lots of current to make lots of power!

Remember! An electrical circuit is just that... a complete circuit. For current to

travel, you must complete the circuit rom the positive terminal to the negative

terminal (which is connected to the vehicle rame). So what ever Gauge wire

you use or power (B+) you must also use or ground (B-).

Note: A 4-gauge power w re needs 4-gauge ground w re!

Use the Wire Sizing Chart! Add up the use values on the ampli ier(s) then

choose the proper size wire based on the distance rom the car battery to the

ampli ier location. Again, always use the same gauge wire or the main ground

as you do or the main power. Always make your ground as short as possible

and secure it to a clean solid sur ace, pre erably the vehicle rame.

Mount ng your Z-Ser es SP ampl f er

Mounting your Zapco ampli ier is easy. Just keep in mind a ew guidelines:

• The ampli ier can be mounted in any direction, on wood, metal, or carpet

• The metal chassis o the amp can be grounded or le t isolated

• The ampli ier requires adequate ventilation. Creating power creates

heat, and cooling requires air. Position the ampli ier with su icient

surrounding area or air supply and keep the end plate and side vents

clear or internal cooling

• Keep the ampli ier out o the engine compartment or other locations

that may cause excessive heat or moisture

• Do not mount the ampli ier to a subwoo er box or other place that may

have excessive vibration

Sett ng Ga ns: Gain pots are not volume controls. Be ore you irst turn on your

system, you should make sure all gain controls are set to minimum. Gain

controls should be used only i absolutely necessary. Turning up gain controls

causes increased noise, makes distortion more likely and reduces the dynamic

range o your system. I you head unit does not have su icient output, you will

get much better results by investing in a line driver to provide more signal to

the ampli ier.
