Bring the music outside

Kicker designed the PX100.2 2-channel amplifier to work in your powersports vehicle, boat, motorcycle, ATV, golf cart, tractor, or any other vehicle using a 12-volt charging system. This weather-resistant music maker fits in the palm of your hand — or on the fairing of your bike — putting out up to 50 watts RMS per channel so you can hear your tunes clearly as you work or play outside.

Optimized for 2-ohm speakers

The PX100.2 employs Kicker's Direct Amp Technology™, using the vehicle's electrical system as its power supply so the amp will run cool even while you're pushing it hard and loud. Kicker recommends the PS5250 5-1/4" Powersports speakers as the perfect match for the PX100.2, as their 2-ohm impedance pulls maximum power from this dynamic little amp.

Product Highlights:

  • 2-channel amplifier (works in any vehicle with a 12-volt charging system)
  • 25 watts RMS x 2 at 4 ohms (50 watts RMS x 2 at 2 ohms)
  • Direct Amp Technology results in 90% efficiency
  • selectable high-pass filter (off, 100 Hz, 250 Hz at 24 dB/octave)
  • preamp and speaker-level inputs (speaker-level input requires an optional adapter)
  • 14- to 10-gauge power and ground leads recommended — wiring and hardware not included with amplifier
  • fuse rating: 10A x 1
  • 7-3/8"W x 2-1/16"H x 3-1/2"D
  • warranty: 2 years
  • Our 60-day money-back guarantee

My system has plenty of power. Who needs an amp?

You might think you don't need an amp because you have a 400-watt system in your car, or because your new stereo puts out 50 watts a channel. But those are peak wattage ratings, which may boil down to 15 or 20 watts per channel, using the more realistic RMS rating. An amp sends your speakers the power they need to deliver your music with clarity and impact, whether you're using factory speakers or high-performance components. And low-frequency reproduction requires lots of power, so an amp is an absolute must if you're adding a sub to your system.

Crutchfield Customer Review (What's this?)

Well, with the right speakers this is better than the big buck Haag tunes that I had purchased. This amp does deliver..

Pros: Small and compact. Fits well under the fairing on any Harley bagger.

Cons: Well, the price. But still cheaper than any competition.

Works Awesome!

Crutchfield Customer Review (What's this?)

I used this unit to power a pair of the 5.25" Kicker Powersports speakers in my Polaris RZR.

Pros: This unit fits extremely well on top of the dashboard substructure under the hood of my machine. It is a greasy addition to any machine where water or dirt are a concern.

Cons: None

Crutchfield Customer Review (What's this?)

Very impressive for its size. Kicker did an awesome job building a motorcycle amp.

Pros: Size, power, and low power consumption.

Cons: None

Great little AMP

Written by: Ed F. from Hammonton, NJ on August 5, 2012

Crutchfield Customer Review (What's this?)

I waited until I had used this AMP for a while. I installed it on my motorcycle front fairing. This amp really is compact, and that makes it very versatile for many different types of installations. I can now hear the music, over the road and wind noise. I mounted it beneath my radio, so it would be air cooled, but out of direct rain and wind interference. The installation instructions were easy to follow; even for this non audiophile. I'm glad I bought and installed this great little piece of equipment.

Pros: Small physical size, with great performance. Not position sensitive. Easy to follow installation instructions.

Cons: Didn't find any problems.

Product Research


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:
    • on/off
    • 100 Hz / 250 Hz; select crossover frequency
  • 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 KiSL speaker level to RCA adapter (item number 206KiSL, 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.
