POWERZONE PZi AMPLIFIERS
INDEX PAGE
Crunch is proud to introduce the finest high end car audio products available and would like to thank you for your continued support.
The PowerZone Series range of products have been designed to a very high level of performance, with features unavailable in any other
products.
All of the amplifiers have variable crossovers built in, with added touches such as subsonic filter, bass equalization and a bass remote control
module option that allows bass control from with in reach of the drivers seat.
To insure years of listening pleasure, all amplifiers have a built in diagnostic mode that will detect shorted speaker leads, low impedance,
dangerous high temperatures, DC shorts and will shut down the amp to help prevent serious damage.

GENERAL INSTALLATION PROCEDURE
1
System Design
Installation
The success of any car stereo system relies on several factors, such as the system design, execution of the installation, and system setup. Please
remember that any system is only as good as its weakest link.
Please remember that higher power systems are not necessarily useful purely for high sound pressure levels, but also to establish a headroom capability, to
reproduce musical peaks cleanly without distortion. Lower power amplifiers will clip earlier than their more powerful cousins, and cause loudspeaker failure when
overdriven, due to the harmonics generated by a clipped signal, thus overheating voice coils.
Amplifiers should be mounted with the fins running horizontally for best convection cooling, to minimize overheating. Purchase the best quality RCAcables you can
afford, for reliability and less engine noise interference in the audio system.
General:
Run the wiring so that RCAcables are at least 18“ away from power and speaker cables. Keep RCAcables away from electrical devices in the vehicle that can cause
electrical noise, such as electric fuel pumps, emission control modules and other on-board electronic modules.
Power and ground connections(see the features matrix on page 9 for proper gauge cables per amplifier):
Use a sufficient gauge power cable and ground cable using the chart below as reference to what size wire you require. PZi series amplifiers require 4 gauge power
wire. In a multi amplifier system, add the total value of the manufacture recommended fusing to get your total system amperage. Some applications may require
multiple runs of power wire to meet the system requirements. In multi amplifier systems it is advisable to mount a large enough fuse right at the battery, and run one
or multiple +12 volt power cables to a fused distribution block near the amplifiers. It is then a simple matter to connect the +12 volt terminal of each amplifier to the
distribution block. During this process, please ensure that the main power fuse is removed to avoid shorting the electrical system. The main fuse must be within 12” of
the vehicles battery.
Ground each amplifier with as short a ground lead as possible directly to the vehicle chassis using 4 gauge wire or equivalent to the size of the amplifiers’ power wire.
Use a ground distribution block, if you wish, but it is extremely important to keep the main ground lead from this distribution block to the chassis as short as possible ,
not more than 12“. The ground connection integrity to the chassis is very important, and the best way to achieve a good, solid electrical and mechanical contact is to
use a large round crimp lug, crimped and soldered to the ground cable. The next step is to scrape the paint off the vehicle chassis , slightly larger than the ground
lug, at the connection point. Drill a clearance hole in the chassis, the same size as the lug hole, and use a bolt, spring washer and nut to securely fasten the ground
lug. Use petroleum jelly to coat the bolt/lug connection, to prevent oxidization with time.
TIP: Use the same approach when installing head units, equalizers or any audio equipment for that matter - run short individual grounds from each piece directly to
the vehicle chassis, to minimize ground loops and system noise.All power, ground and speaker connections should be crimped and soldered for reliability. Make sure
that none of the cable insulation can chafe against exposed metal in the vehicle, causing short circuits to the chassis.
Safe connection sequence:
After all cables are run, connect speaker wires to the speakers and amplifiers, then run and plug in RCAcables. Next, connect all power, ground, and remote turn on
leads. Now connect all +12 volt cables to the amplifier/s and distribution blocks and fuse holders. Finally, connect the main +12 volt cable to the battery, with the main
fuse removed, and we are almost ready to power up the system.
Power up the system:
The following procedure may seem like overkill, but there is nothing more frustrating when turning on a system for the first time, and it does not work properly
immediately.
First, make sure the head unit is off, and turn all level controls to minimum (counterclockwise), including the head unit volume control. Set all equalizers to 0 dB (no
boost), and all crossover frequency controls at approximate frequencies, as recommended by the loudspeaker manufacturer. Set all input selector and crossover
switches as required for the application. Remove all amplifier fuses, and insert the main fuse at the battery. If the fuse does not blow, you can insert the fuse in one of
the amplifiers, and we are ready to turn on the system. Turn the head unit on, insert a CD, or select a radio station, and increase the head unit volume control. If the
system sounds fine, turn off the head unit, and install fuses in the remaining amplifiers, one by one, till the complete system is powered up and functioning properly.
WOOD
It is highly recommended that the amplifier be mounted to a board of MDF or other solid
structure using the 4 mounting screws provided. Avoid mounting the
amplifier to metal as this can introduce noise and other unwanted issues. When mounting
the amplifier, ensure that it is mounted HORIZONTALLY, as shown in the diagram above, for
optimal heat dissipation. Mounting amplifiers to speaker enclosures is not recommended as
this can cause damage to the amplifier components. When choosing a location for
mounting the amplifier, ensure that you check for clearance from wires, gas tank, electrical
devices and brake lines etc.
NOTE: This Matrix is a general rule
of thumb. Please refer to the
manufacturers specific
requirements. PZi specifications
can be found on page 9.

SETTING UP SYSTEMS AFTER INSTALLATION FOR BEST PERFORMANCE
10
PZi1000.1 / PZi1500.1 / PZi2000.1D / PZi3000.1D
General:
At this point you are ready to get more specific on the settings for your amplifier.
Subsonic:
This setting acts as a low frequency cut off for your system bass reproduction. The point that you set it at cuts off any frequencies from reproduction beyond this point. The 12 o’clock
position is a great starting point. EXAMPLE: If you adjust the Subsonic to 25Hz, the amplifier will not play frequencies below 25Hz but will play frequencies from 25Hz to the chosen Low
Pass frequency.
Bass EQ:
This setting is a fixed bass boost at 45Hz that is variable from 0-10dB. This feature provides impact to your bass, but if not adjusted correctly, it can be over used and cause damage to
your subwoofers and amplifiers. It is best to slowly turn this setting clockwise until the desired punch is felt. It is not recommended to exceed the 12 o’clock position unless listening at a
low volume or a low recording quality as this can result in high distortion and possibly clipping.
Low Pass:
The Low Pass control acts as a ceiling and doesn’t allow frequencies to the right of the desired setting to be reproduced. The 12 o’clock position is a great starting point. EXAMPLE: If you
adjust the Low Pass to 80Hz, the amplifier will not play frequencies above 80Hz but will play frequencies from 80Hz to the chosen Subsonic frequency.
Phase:
The variable Phase adjustment allows you to change the relative time that the waveform meets your ear. With standard subwoofer installations where the subwoofer is behind you, the
Phase should generally be at 0. When subwoofers or woofers are in the kick panels or door panels, the Phase adjustment is useful in delaying the timing of the wave meeting your ear by
adjusting the potentiometer to 180 degrees.
Level Control Setup:
Ensure that the Level is turned completely to the left prior to turning the system on. Next you should insert a CD or cassette that you are familiar with to use as a reference, and turn the
head unit volume control to about 80% of its full setting. The system sound level will of course be very low, and the following procedures will help you to match the amplifier input
sensitivities properly to the head unit output signal level.
It is important to match the amplifier LEVEL input sensitivity to the Radio/CD output sensitivity. This can be located in the Radio/CD manual.
If the Radio/CD output sensitivity is 2 volts, then adjust the amplifier LEVEL input to 2 volts.
If you are not sure what the Radio output sensitivity is, follow these general guide lines:
Turn the level control up slowly, till you hear distortion, then back off a few degrees on the control. If at any point your amplifier goes into protection, you will need to turn the Level to the
left a bit and then try again. If you reach a point where the output does not increase, stop turning the Level control to the right as the amplifier/subwoofer combo has reached its maxx
output in this application.
Sit back and enjoy the music!
PZi100.2 / PZi250.2 / PZi325.2 / PZi100.4 / PZi124.4 / PZi550.5
General:
At this point you are ready to get more specific on the settings for your amplifier.
High Pass:
-When in Hi Pass operation, this setting acts as a low frequency cut off for your system reproduction. The point that you set it at cuts off any frequencies from reproduction beyond this
point. The 12 o’clock position is a great starting point. EXAMPLE: If you adjust the High Pass to 100Hz, the amplifier will not play frequencies below 100Hz but will play frequencies from
100Hz to the chosen Low Pass frequency.
-When in Low Pass/Bandpass operation, this setting acts as a low frequency cut off for your system reproduction aka Subsonic Filter. The point that you set it at cuts off any frequencies
from reproduction beyond this point. The 12 o’clock position is a great starting point. EXAMPLE: If you adjust the High Pass to 25Hz, the amplifier will not play frequencies below 25Hz
but will play frequencies from 25Hz to the chosen Low Pass frequency.
-When in Flat/Full operation, the High Pass crossover is bypassed.
Bass EQ:
This setting is a fixed bass boost at 45Hz that is variable from 0-12dB. This feature provides impact to your bass, but if not adjusted correctly, it can be over used and cause damage to
your speakers and amplifiers. It is best to slowly turn this setting clockwise until the desired punch is felt. It is not recommended to exceed the 12 o’clock position unless listening at a low
volume or a low recording quality as this can result in high distortion and possibly clipping.
Low Pass:
The Low Pass control acts as a ceiling and doesn’t allow frequencies to the right of the desired setting to be reproduced. Turning the potentiometer all the way to the right is a great
starting point. EXAMPLE: If you adjust the Low Pass to 120Hz, the amplifier will not play frequencies above 120Hz but will play frequencies from 120Hz to the chosen Hi Pass or
Subsonic frequency.
-When in Hi Pass operation, this setting is bypassed.
Level Control Setup:
Ensure that the Level is turned completely to the left prior to turning the system on. Next you should insert a CD or cassette that you are familiar with to use as a reference, and turn the
head unit volume control to about 80% of its full setting. The system sound level will of course be very low, and the following procedures will help you to match the amplifier input
