Our Product Research Team
At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.
That's because we have our own in-house Product Research team — they open the box,
verify contents, check the owner's manual, and record dimensions, features and specs.
We stay on top of new products and technologies to help people make informed choices.
Overview: PX series amplifiers are designed for motorized
vehicles with small battery/charging systems; Kicker's new Direct Amp Technology
uses the vehicle's charging system as its power supply, offering 90-percent
efficiency. As a result, the PX100.2 draws a maximum of less than 10 amps and
outputs solid power without taxing the limited charging capacity found on
motorcycles, utility or other vehicles. Little ventilation is required and
with its small footprint, the PX100.2 can be installed in motorcycle saddle
bags or fairings, glove compartments, or other small spaces.
Power Output: The PX100.2 is a stereo amplifier and is 2Ω
stable. The power output is 25 watts RMS x 2 at 4Ω (<1% THD+N) and
50 watts RMS x 2 at 2Ω (< 1% THD+N). The amp was designed to power
one or two pair of PS5250 full range speakers (available in 4Ω and 2Ω),
but it can also be used with other speakers.
Controls: The controls are under a rubber cover:
- High Pass Crossover: two switches:
- 100 Hz / 250 Hz; select crossover
- Input Level: select high (speaker level)
or low (line level)
- Auto Turn-on: select 12V (amp turns on
when +12 volts is applied to the remote wire in the harness)
or DC (amp turns on when a 6 volt surge is detected from a
speaker level source)
- Gain: rotary knob; adjust to match the
output of the source unit
Wiring: All the wiring connections are in one Molex plug (power,
ground, remote turn-on, speaker output, RCA input).
Speaker Level Input: When connecting a speaker level source, cut
the RCA plugs off and splice into the remaining wire. If you prefer not cutting
the RCA plugs off, use the Kicker ZS ZISL speaker level to RCA adapter (item
20609ZiSL, sold separately).
Differential Input: The differential input circuit reduces
the likelihood of picking up any engine noise.
Weather Resistant: The PX Amps are weather-resistant, using
a conformal-coated circuit board for protection against the elements. They also
include stainless-steel mounting hardware.
