Based on the same design philosophy as the original KICKER Amplifier,
the ZR-Series amplifiers from Stillwater Designs expand and improve the
standards for car audio amplifier performance. Features that defined the
way an amplifier should be built, attention to detail, flexibility, and pure
clean power have been retained and some important new
performance/reliability features have been added.
FEATURES & CONTROLS
The design goals for the ZR-Series amps were simple yet crucial: build the ultimate ampli-
fiers available for the brutal environment of a vehicle.
A new heatsink design provides maximum heat dissipation when air flow isn’t ideal. In
addition to the existing forms of protection already in effect (thermal, overvoltage, and
reverse polarity), a new short circuit protection circuit will allow the amplifier to operate
into a variety of loads including 1 Ohm stereo and 2 Ohm mono.
Gold plated custom tooled speaker and power connectors maximize power transfer and
damping. To improve the thermal stability, sound quality, and output power we have
upgraded the power supply switching MOSFETs.
Surface mount devices are used extensively throughout the design to increase reliability.
Features carried over from the last generation of amplifiers include:
ZRX Crossover Module included.
Active Signal Processing Modules are less expensive than outboard signal processors and
eliminate the possibility for electrical noises to enter the system.
RCA output jacks provide a simple method for daisy chaining multiple amplifiers, espe-
cially when the plug-in modules are used.
Optical isolation between the signal and power grounds has proven very effective to
keep automotive electrical noises from entering the signal path.
For the best sound quality possible we have eliminated coupling capacitors from the sig-
nal path through the use of a DC servo circuit.
Silent turn on/off circuitry eliminates pops to protect your speakers and makes your
system ready for competition.
Multiple amplifiers can be daisy chained without signal degradation because the input
impedance is 22,000 Ohms.
Stillwater Designs recommends that the amplifier be installed at an authorized dealer.
The length of your KICKER amplifier’s warranty is three times as long when installed by an
authorized KICKER dealer.
