Mission Statement Committed to excellence Zapco is dedicated to the pursuit of audio fidelity. Our prime objectives are to design and produce audio products of unsurpassed quality, to provide unparalleled support and service for these products, and to conduct business in a manner that will enhance the quality of life for all involved. Experience: Knowledge from doing There is absolutely no substitute for experience; that is a simple fact of life.
Power and Wire Gauge The wire you use for the power and ground connections of your amplifier is absolutely critical. The plain simple fact is that it takes power to deliver power. If you do not provide the proper amount of 12V power to your amplifier, you will never reach the full power potential of the amp. Take a look at the chart below. If you want to have any respectable amount of power for your amp, you need a 4-gauge wire to the trunk as a bare minimum.
Gain Setting Matching Your Components for Best Sound Proper gain setting is one of the most important factors in setting up a stereo system. Unfortunately, gain setting is quite often done wrong. Turning up the gain of an amp is the very last thing you should ever do to a system. An amplifier is a step up transformer. Period. Any signal you put in is boosted by a fixed factor, whether it's music, hiss, or any other noise. A large number of noise problems are simply a matter of improper gain settings.

POWER CONNECTION Z-150.2 25Ax2 GROUND to REMOTE Turn-on from HEAD UNIT HEAD UNIT BATTERY GROUND Z-400.2 / Z-150.4 GROUND Caution to REMOTE Turn-on from HEAD UNIT This amplifier is not supplied with internal fuse. Make sure you install an in-line fuse holder near the +terminal of battery. Z-400.2:Recommend 100 Ampere fuse. Z-150.4:Recommend 80 Ampere fuse.
POWER CONNECTION Z-150.6 GROUND to REMOTE Turn-on from HEAD UNIT Caution This amplifier is not supplied with internal fuse. Make sure you install an in-line fuse holder from the +terminal of battery. Recommend 100 Ampere fuse. HEAD UNIT BATTERY GROUND +12V Power Disconnect the Battery ground. Connect the +12V terminal of the amplifier to the + terminal of the battery using the appropriate guage wire cable. Always use the same guage wire for Power and Ground.

TROUBLE SHOOTING GUIDE This power amplifier has protection features to prevent most forms of damage. If the unit senses excessive heat, short circuited speakers or overload, the protection indicators will be lit and the system will be turned off. Prior to checking the wiring for any fault, you should turn all level controls down and turn off power. If the amplifier shuts down due to excessive heat, the protection indicators will not be lit: simply allow the amplifier to cool down.
