Zapco - The Driving Force Since 1974
Zapco is a company dedicated to the pursuit of audio fidelity. It's prime objectives being to design and manufacture 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 its users.

Experience Equates To Knowledge From Doing.
There is absolutely no substitute for experience; that is a simple fact of life. Another simple fact is that Zapco has been the leader for almost fifty years now, still constantly redefining quality standards for the car audio industry. These years of experience have led to a thorough understanding of the challenges that are unique to the world of car audio. Zapco's relentless quest for sonic purity consistently yields imaginative designs that utilize the most innovative technologies. The resulting products set the criteria by which all others in the industry are judged.

Z-SP Series - The Blended Perfection Of Articulation And Force
As a respectable lady or gentleman you naturally pursue the very best performance from your amplifiers, conducive to sound quality being an important prerequisite. However also residing within you is a certain wild streak, one which haphazardly likes to push the volume to extremes. Meaning serious power output is also paramount. That's going to take a masterfully designed amplifier to blend such accuracy with copious amounts of output. Welcome to the Z-SP range of powerhouses from Zapco; a bold encounter bringing together the elegance of the Z-AP range and the brute force of the Z-II range.

Design Ideologies
The esteemed Z-SP series comes from the need to outfit cars that compete in the competition category called Street Challenge or Street Demo. This is harder on the components and creates more heat than audiophile listening because they will be played full power, full time. Put simply; they need to produce the highest volume possible while still maintaining absolutely clear sound. It’s not like audiophile listening so much but more like a dance hall or rock concert.

A New Dawn Of High-End Power
The Z-SP series amps were a chance to make a completely new project. To reach their end-goals, the astute engineering team at Zapco first developed a new forced air cooling system in a chassis with internal heat sink fins and fans to blow the heat off the chassis. Fans blow on to the fins 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 of the amp. This thermally efficient design got the engineering team half-way to their goal.

Thermal Goals Realised
They then developed a new space-age material to insulate the output transistors. This material draws heat off the devices much faster than the standard insulators. Meaning the engineers could transfer the heat from the devices to the chassis faster, thence get to removing said heat off the chassis faster. The result was that Zapco now had a range of amplifiers that can be cranked up to full volume and play that way all day long.

Enhancements Aplenty
Not only this, for many circuitry upgrades were incorporated into the design along the way. Things like multiple crossovers, multiplier switches, subsonic filter controls, variable Bass Boost, variable Gain, auxiliary RCA output and an external dash remote if required.

On most amplifiers all these pre-amp controls give you more versatility but they also rob you of signal quality. But in the Zapco Z-SP series amplifiers, even with crossovers and bass boost you get over 103 dB signal-to-noise ratio, less than 0.1% total harmonic distortion (THD) and greater than 60 dB channel separation. On top of this all physics then provides a generous five to ten percent power gain from increased thermal efficiency that reduces the de-rating of the output devices.

Design Features
The stellar heritage of this astute and masterful designer, together with its ever-increasing technical acumen; is conducive to these components featuring a vast array of impressive design ideologies and latest technological advancements. Some of which include:
– Two channel Street Power competition amplifier.
– Wide range dual crossovers allowing band-pass filtering.
