Page 4: The New Zapco Z-Series Amplifiers
The re-birth of the Z-Series In 2012 Zapco introduced the new Z-Series of SQ amps. These amps were not conceived so much by our engineers, as by input from audiophiles and car sound fanatics around the world. Starting about 2004, at Zapco training seminars in... -

Bottom line, we have improved the amplifier at the same time we brought the price down. Who ever does that! Of course, that's just talk, but here's the beef. For the Class AB full range Competition Amps: • A new TI op-amp that give the Z considerably better signal to noise ratio, with a lower floor noise •... -

Z-KD II; more useful, better looking and even better sounding. Class A/B amps for full range use and Class D amps for bass. Whatever your needs, the new Zapco Z-II Competition series amplifiers bring you better features, better power, and better sound. -
Page 7: Before You Start Your Installation
Before you start your installation ZAPCO highly recommends that a fuse or circuit breaker be placed within 18" of the battery. Although you will add a fuse or fuse block near the amplifier it is still a possibility that a pinched power wire between the component fuse and the battery could result in a short, or even a fire. -
Page 8: Planning Your Power Connections
Planning your power connections The power end plates of the Zapco Z-series amplifiers carry the power connections and the Speaker connections and vary somewhat by the number of channels. For example, the power end of the Z-150.6 II has (of course) Speaker connections for six channels. -

Some words about Power and Ground Note: The second most common cause of underperforming amplifiers is insufficient power current or a pour power connection. The most common cause of underperforming amplifiers is insufficient ground current or a bad ground connection. 12-volt current: Battery Power works only if it travels in a complete circuit from the battery positive terminal to the battery negative terminal. -

Page 14: Z-150.2 Ii Speaker Wiring
Speaker Wiring of the Z-II Class AB Amplifiers The Very Basics • No speaker wires can be shorted to, or touching either ground or each other. This will put the amp into protect and may damage the amplifier • When bridging the left and right channels of any amplifier, you use the left channel (Ch1) positive and the right channel (Ch2) negative, as indicated on the chassis by the speaker terminals Z-150.2 II Speaker Wiring... - Page 15 4Ω ~ 8Ω Note: Take note that 4 Ohms is the minimum load when bridging, since each channel will see only 1/2 the load (2 ohms). Do not bridge with a 2Ω woofer 3Ch Mode It is possible to run the 2-Channel amps in “3-channel” mode by running a pair of speakers for the mids and highs on left and right channels, and at the same time run a woofer bridged between the L+ and R- terminals as shown.

Z-150.4 II Speaker Wiring Standard 4Ch Mode The Z-150.4 II four channel amplifier is virtually two 2Ch amps in one chassis and each set of four speaker terminal can be used exactly as you would use a 2Ch amp. The advantage of a four channel amp is primarily the saving of ace (and a little money). - Page 17 4Ch 2-Way Mode With the unique features of the Z-Series amplifiers you can also use the Z-150.4 II to drive a 2-way system with the front channels for highs and the fear channels for lows. The unique crossover will let you separate high and low like most 4Ch amps, but with the added range provided by the multiplier (x10) switch you can actually have a tweeter crossover as high as 5,000Hz on the front channels.
- Page 18 2-Way w/Bridged Mono Sub A similar setup uses a pair of full-range speakers with a mono subwoofer. • Front filter is set to HPF, the Multiplier is off (out), HP frequency is set just above the bottom of the full-range speaker's frequency range, where you will also set the woofer crossover •...

Z-150.6 II Speaker Wiring 6 Ch 6 speakers The Z-150.6 II is a 6-channel amp that can drive six speakers from 6, 4, or 2 channels of input. Note that channels 5 and 6 are arranged top and bottom and CH5 has + and - reversed from the other channels. - Page 20 A One-Amp, Active 3-way System The Z-150.6 II is a superbly versatile piece of gear. With the crossover features of this amp you can run a completely active 3-way system. You can run it as Tweeter , midrange, bass. You can also ruin it as tweeter, band-passes mid-range, and band passed mid-bass and then use a separate subwoofer amp.
- Page 21 High Power 2-way System The system below provides plenty of power for a 2-way active system with even the lowest efficiency front speaker system. Each speaker has 550 watts RMS @ 4Ω • Since all speakers are being bridged, they must all be minimum 4Ω ~ 8Ω impedance •...

Z-KD II Input Ends The Z-1KD II, Z-2KD II, and Z-3KD II share the same endplates and the same controls. The controls of these amps are designed specifically to allow you to maximize the bass performance of your system. 1• RCA Inputs 6•... - Page 23 Notes on the Mono Bass Amp controls: • Strapping - Two Z-II mono bass amps can be bridged together to operate a single voice coil (speaker) giving it roughly twice the power of a single amplifier. When two amps are "strapped" the Master amps controls will control crossover, sub sonic, bass boost etc.

Speaker Wiring of the Z-II Class D Bass Amplifiers Speaker wiring is identical for all three Z-II Class D amps: There are four connections for speakers, but note that the 2 left hand terminals are both positive and the two right hand terminals are both negative. This is to make hooking up multiple woofers easier. - Page 25 Strapping two amps to one speaker voice coil When you strap two amplifiers together, you are using one amp for the positive side of the signal and one amp for the negative side. Internally this is accomplished by reversing the polarity (or phase) of the input to the slave amp. After strapping, each amplifier will see 1/2 of the load.
