Our take on the Kicker KX500.2

by Steven Johnson
Kicker

Want to kick your system's performance up a notch? Kicker's KX500.2 amplifier cranks out ultra-clean power and boasts a long list of cool features. The built-in variable crossover adjusts the frequency output of the amplifier for different applications. Looking for some low-end slam? Bump up the lows with up to 18 dB of bass boost at 40 Hz.

If you're building a multi-amp system, preamp outputs pass a full-range signal to a second amplifier. Speaker- and preamp-level inputs hook you into any system, even a factory radio. A protection circuit guards the amp against voltage problems or overheating. Set your amplifier's volume from your front seat with the remote gain controller.

Details:
  • stereo or bridged mono output
  • Tri-way capable (Tri-Way crossover required)
  • 125 watts RMS x 2 at 4 ohms
  • 250 watts x 2 at 2 ohms
  • 500 watts x 1 in bridged mode
  • speaker- and preamp-level inputs
  • preamp outputs (pass full-range signal to another amp)
  • high-pass/low-pass crossover (variable 50-200 Hz, 12 dB per octave)
  • bass boost (0-18 dB at 40 Hz)
  • remote gain controller with 20-foot cable
  • frequency response 20-20,000 Hz
  • requires 4-gauge power and ground leads — wiring and hardware not included with amplifier
  • unregulated Class A/B power supply offers a significant increase in power at 2 ohms
  • 12-1/2"W x 2-5/8"H x 10-1/4"D
  • 1-year warranty

Features

Cosmetics: The amplifier is black and it has a dark gray, removable metal shroud.

Amplifier Shroud: The amplifier has a metal shroud that must be removed before installation, allowing access to the amplifier's inputs and outputs. Once the amplifier is installed and all the connections are made, you can re-install the shroud to hide the connections on the amplifier, or leave the shroud off to save space. With the shroud removed, the amp has the following dimensions: 18.8750"W (19.8750" with RCAs) x  9.508"D x 2.304"H.

Kicker "Living Loud" Certified Power Certificate: The amplifier comes with a certificate that informs you of the total maximum wattage of the particular amplifier, along with the model number, serial number, tested date, and whether the amplifier passed the total harmonic distortion, signal-to-noise ratio, and protection circuit tests.

Speaker-level Inputs:  High-level input connections are included to allow use with sources that do not have RCA preamp level outputs. 

PAST RCA Line Outputs: PAST stands for Pre Amp Signal Transfer, which means that this amplifier has a set of full-range line outputs. The line outputs allow you to pass a preamp-level signal from this amplifier to another amplifier. This eliminates the need to use RCA splitter cords to distribute signals to two amplifiers. Note: Regardless of whether you use the RCA inputs or the speaker-level inputs on this amplifier, you will still be able to use the RCA outputs.

Built-in Variable Electronic Crossover: The built-in crossover allows you to select high-pass for satellite speakers, low-pass for subwoofers, or bypass for full-range operation. The crossover frequency is variable from 50 to 200Hz.

SORT (Short circuit, Over-voltage, Reverse polarity, Thermal) Protection Circuitry: The SORT protection circuitry guards against accidents and undesired operation. The Power LED on the left side of the amp glows green and the power indicator on top of the amp glows red when the amplifier is hooked up correctly and SORT has not been engaged. If the red Protection LED illuminates, SORT has been engaged and the amplifier is in protect mode until the problem is resolved.

KickBass Bass Boost: The KickBass bass boost circuit provides up to 18dB signal boost at 40Hz.

SAMS (Stereo And Mono Simultaneously): With a Tri-mode adapter (item # 127TM100), this amplifier can run satellite speakers and a sub at the same time.

Remote Bass Level Control: This dash-mounted remote unit allows you to adjust the output level of the amplifier. This can only be used when the amplifier's crossover switch is set to Lo-Pass. The control has the following dimensions: 2.199" W x 1.715" D (2.196" including the knob) x 1.186" H.

Controls

Top of Amplifier:

  • KickBass Bass Boost Control: rotary control that allows you to adjust the bass boost, centered at 40Hz, from 0 to +18dB
  • Gain: rotary gain control that allows you to adjust the output level
  • Variable Crossover Frequency Control: allows you to adjust the crossover frequency from 50-200Hz

Right Side of Amplifier:

  • Crossover Mode Switch: allows you to select "Hi Pass", "Lo Pass", or Off.

Inputs and Outputs

Left Side of Amplifier: 

  • 12+ (power): gold-plated screw terminal (terminal is 0.554" wide)
  • REM (remote turn-on): gold-plated screw terminal (terminal is 0.350" wide)
  • GND (ground): gold-plated screw terminal (terminal is 0.554" wide)
  • Fuse: two 35-amp fuse

Right Side of Amplifier:

  • Left Speaker Output: gold-plated screw terminal (each terminal is 0.350" wide)
  • High Level Input: Molex plug input for included harness
  • RCA Input: gold-plated RCA line input jacks
  • RCA Output: gold-plated RCA line output jacks
  • Right Speaker Output: gold-plated screw terminal (each terminal is 0.350" wide)
  • Remote Bass Level Input

Specifications

Dynamic Power Rating (measured at 14.4V):

  • Bridged Into A 4-Ohm Load: 570 watts x 1
  • Per Channel Into A 2-Ohm Load: 285 watts x 2
  • Per Channel Into A 4-Ohm Load: 205 watts x 2

Continuous Power Rating (measured at 13.8V):

  • Bridged Into A 4-Ohm Load: 500 watts x 1
  • Per Channel Into A 2-Ohm Load: 250 watts x 2
  • Per Channel Into A 4-Ohm Load: 125 watts x 2

Warranty Note

Warranty Note: The warranty on this amplifier is 1 year parts and labor. If installed by an authorized dealer, the warranty is extended to 3 years parts and labor.

Wiring Recommendation

Wiring Recommendation: This amplifier uses two 35-amp fuses, so its fuse rating (70-amps total) exceeds that of typical 4 gauge wiring kits, which tend to include a 60-amp fuse. For 70-amp fuse protection, the fuse included with a pre-packaged wiring kit should be replaced with an 70-amp AGU fuse (sold separately).

SUPA "BAMP"

Written By dBHEDZ, ATL on Tuesday, October 02, 2012
 
I hv this amp wired @ 1.5 ohms mono to a JL 12w6. Not in spec I know but seems to be stable and super strong, it pushes my sub to the max. My gain is set @ 1:oo and I may hv2 back it down a bit. The bass is really clean and the double beats are clear and strong. Compared to my RF 200ix, this amp is way more powerful. I hv to gv the overall sound quality to the punch amp. The kicker seems to be very efficient as it does not drain my 130a alternator. It's currently wired with an 8g power & ground kit, which I will upgrade to 4g asap.
Pros:
Powerful, fan cooled, Class A/B topology, quality connectors, RCA pass thru output jacks, 18 db bass boost @ 40 Hz. Seems to be 2 OHM stable in mono configuration.
Cons:
It's huge... 17-5/8"W x 2-5/8"H x 10-1/4"D. Remember this is not a Class D amp!
