Our take on the Kicker IX500.1

by Buck Pomerantz
Kicker

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.

Kicker technology = big bass from a small amp
The compact chassis of this Kicker IX Series amp houses a technical powerhouse. It uses the same voltage-boost technology found in some electric-hybrid vehicles to achieve over 90% efficiency — which means you get more power from a smaller, cooler amp. Kicker combined this high-current design with Class D digital technology to unleash more watts per cubic inch than most amps. And an IX Series amp runs so cool you can stack multiple amps together for a professional-looking installation.

500 watts with plenty of control
The IX500.1 mono subwoofer amplifier delivers up to 500 watts RMS to your sub so you can enjoy a big kick to your music. You can shape the low-end impact with the low-pass filter, and the subsonic filter eliminates bass below 25 Hz so your subs play more efficiently. Noise-reducing technology removes electrical system interference as it enters the amp's inputs, allowing your subs see the only cleanest musical signal possible. Kicker includes a wired remote control so you can dial in just the right amount of bass boost from the driver's seat.

Features

Class D Amplifier Design: The Kicker IX500.1 (2011 version) is a mono-block Class D amplifier, which uses digital switching to amplify audio signals. This design results in high efficiency and less heat. The Class D design also allows the IX500.1 to have a very small footprint for ease of installation.

Mono-Power Amp Design: The Kicker IX500.1 is designed with specific features to power your subwoofers with a frequency range between 25-200 Hz. The amplifier can handle impedance loads down to 2 ohms. The amplifier is rated at 275 watts x 1 channel RMS @ 4 ohms (25-200 Hz, 1% THD). At 2 ohms, the amp is rated at 500 watts x 1 channel RMS (25-200 Hz, 1% THD).

Note: This amplifier is not designed for full-range operation.

Power Supply: The Kicker IX-series mono subwoofer amplifiers use a boost-converter power supply for the highest sound quality and efficiency. Boost-converter technology allows the amp to achieve efficiency of more than 90%. Because there are fewer internal parts, the amp has a smaller form factor, and results in cooler operation, better reliability, and overall excellent performance.

CEA 2006 Compliant: The Kicker IX500.1's power ratings are measured according to the strict standards dictated by the Consumer Electronics Association (CEA). These standards allow you to accurately compare the rated power output of all CEA 2006-compliant amplifiers, even if they come from different brands. Manufacturers who adhere to the standards can display the CEA 2006 logo on their products and packaging.

Kicker Livin' Loud Certified Power Certificate: The amplifier comes with a certificate that indicates 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.

Low Pass Filter: The Kicker IX500.1 is equipped with a selectable electronic crossover. This continuously variable low pass filter can be set between 50 Hz and 200 Hz with a slope of 24dB per octave. Properly set, the low pass filter creates a smooth transition between the subwoofer and the sound system's full-range speakers.

Subsonic Filter: The amp features a 24 dB/octave subsonic filter fixed at 25 Hz. Ultra-low frequencies that cannot be reproduced by a subwoofer do not become sound but become unnecessary oscillations, which affect sound by causing distortion. These frequencies also waste amplifier power and can cause damage to speakers. The built-in subsonic filter cuts the frequencies below 25 Hz to improve the reproduction performance of the speakers by eliminating harmful distortion.

Note: The subsonic filter is not defeatable.

Auto Turn-On: The 3-way Auto Turn-On switch offers three options:

  • +12 V: The amp turns on when +12 volts is applied to the remote terminal.
  • DC Offset: The amp turns on when a 6 volt surge is detected on the signal inputs (from a speaker-level source); in this mode the amp's remote terminal acts as a +12 volt output to turn on another component.
  • Audio: The amp turns on when an incoming audio signal is detected; in this mode the amp's remote terminal acts as a +12 volt output to turn on another component.

Input Level Control: To accommodate the varying range of signal levels coming from today's factory and aftermarket radios, the Kicker IX500.1 features a switchable input level control. When the switch is set to Low level, the amp can accommodate an input signal of 125mV-5V. At High level, the amp will accept 250mV-10V signals. This means that no matter what kind of radio is connected to this amplifier, the appropriate gain control adjustment can be made to ensure loud, clear, distortion-free music.

Gain Control: With the Input Level Control switch at the appropriate setting, you can set the rotary Gain Control to match the output of the source unit. The Gain Control adjusts with a flat-head screwdriver, and can be set between 0 and 11.

KICKEQ Bass Boost: When you want more bass out of the amplifier, you can adjust the KICKEQ Bass Boost control. The bass boost is centered at 40 Hz, and can be adjusted between 0 and 18dB.

ZXRC Remote Bass Control: The IX500.1 comes with the ZXRC Remote Bass Control, which allows you to control the output level of the amplifier from the front of your vehicle. The wired remote bass level control comes with a mounting bracket to mount it under your dash. The supplied 20' cable, with RJ-25 phone plugs at each end, connects the wired remote bass level control to the amplifier.

Note: The ZXRC Remote Bass Control measures 2.25" wide x 1.25" high x 2.375" deep.

Soft-Start Circuitry: The Kicker IX500.1 contains "soft-start" circuitry that lessens initial shock load when powering up the amplifier, and a muting circuit to eliminate audio distortion that might surge down the line.

Protection Circuitry: The IX500.1 has protection circuitry that will turn the amp off in the event of overheating, over voltage (power input), under voltage (power input), short circuit (speaker output), and over current (speaker output). If the Protection LED on the front side of the amp illuminates red, the protection circuit has engaged and the amp will not play until the problem is resolved.

Stackable: The optional Kicker IXSM stacking mount (206IXSM, sold separately) allows you to stack two Kicker IX-series amplifiers on top of one another.

Connections

Power Connections: The power and ground connections are set-screw terminals that will accommodate up to 4-gauge wire. The remote turn-on set-screw terminal will accept up to 8-gauge wire. The included 3mm Hex key is required to tighten/loosen the terminals.

Speaker Outputs: The Kicker IX500.1 is equipped with one pair of speaker terminals. Both speaker terminals are set-screw terminals that will accommodate up to 8-gauge wire. The supplied 3mm Hex key is required to tighten/loosen the terminals.

RCA Input Connector: The amplifier is equipped with one pair of RCA inputs, which can be used for a line level or speaker level input signal. If the source device doesn't have preamp level outputs, the KISL speaker wire to RCA adapter is needed and the Input Level switch should be set to High.

Line Level Output: The amplifier has a pair of RCA line level outputs for feeding a signal to another amplifier. It is the same signal that is input through the line inputs. The amplifier's crossovers have no effect on the line level output signal, however, if the input signal is crossed over at the source unit, the filtered signal will be passed on to the second amplifier.

Great amp!

Written By DustinG, Sidney, MT on Friday, February 03, 2012
 
I own the "IX 1000" which is a step up from this "IX 500" but i figured since i own basicaly the same thing i could be helpful. These Amp's are the real deal. Very Accurate Bass is produced from these amps. Great range of tuneing options. Easy install and easy to opporate, and fits almost anywhere! The "Bass Knob" makes it really easy to tune the bass to any song in a snap. so you can be shaking the mirrors to a Rap song, and tune your bass down for some rockin'roll with a simple, easy, turn of a small knob. Great technology, amp stayes cool and delivers clean, powerful, bass even on hot summer days! this IX500 Would go great with a Alpine Type R 12" but keep in mind! these amps have the power to blow subs so be careful! I have two Alpine TypeR 10" subs, hooked up to my IX1000. it is dangerous to drive with them cranked up (blured vision, and you cant hear a frate train comeing at you). this amp allowes them to rattle my chevy 1500 to pieces. i have even had someone vomit in my back seat because they tried to eat while this amp was delivering chest pounding, bone rattling bass to my subs. i recomend kicker IX series amps to anyone who wants a Honest, Reliable, Clean, Raw, POWERFUL, power sourse. 5 stars Good work Kicker!
