Upgraded power supply, top end audiophile grade internal components, shortened signal path, custom built pots and more. Then we took out anything that wasn’t needed for sound quality (crossovers, tone controls, etc.) and redesigned the board and gave each LX amp its own numbered badge. They are built for the true audiophile.

Z (1st Series)
The Z-Series of Zapco amplifiers is the result of our experience over the last 40 years with the technology of sound reproduction, combined with what we have learned in consultations with the home and car audiophile communities over the last few years about human perception of sound.

ST-D (1st Series)
Today’s technology has allowed us to develop a line of great sounding full range Class D amps at an affordable price range and in a size that’s an easy fit in today’s smaller cars. Small car doesn’t have to mean small sound, and you won’t have to give up the back seat for an amplifier.

The C2K Competition Series were produced from 2000 to 2007. They ruled both the SQ and the SPL lanes for years. There was even talk of making the C2K6.0 illegal for SPL because it was unfair competition.

Beginning with AG in '97 through the last Reference in 2007 the line was basically same. Small changes were made from year to year and some models in this manual weren't in the line in until 2002. Form, function, power, and model numbers were constant in all the AG/Reference amps.
