About the Kicker 42IQ500.1
Kicker's high IQ
Kicker's high IQ
Kicker has built the ultimate sound improvement, combining a powerful Class D amplifier with a digital signal processor in order for you to get the high-fidelity sound you want in your car. The amp comes with Kicker's TWEEQ™ sound-tuning software, run on your PC, iOS, or Android device, that helps you dial in your sound just the way you want it.
Power and brains
Kicker's Q-Class IQ500.1 subwoofer amplifier packs a 500 watts RMS punch, so you know you'll hear your bass loud and clear. You don't have to use any app or software to get great-sounding bass with this amp — it has its own onboard tuning controls, including low-pass and subsonic filters and Kicker's EQ+ bass boost. A Panel Lock button disengages the onboard controls when you do want to run things with the TWEEQ app.
TWEEQ functions and features
When you first launch TWEEQ, you'll be prompted to begin a configuration wizard that'll take you step by step through the process of selecting the different settings for speaker sizes, types, and distances. This leaves you with what Kicker calls a basic setup, a big improvement over factory sound that'll satisfy most music lovers.
The advanced features let you really get down to the nuts and bolts of sound. You'll have access to a 31-band EQ, fully adjustable crossover filters, time-alignment, and a limiter/compressor, all there to help your system sound perfect.
More for you
The IQ500.1 comes with an IQRC wired remote that lets you control the volume and bass boost from the front seat. An optional IQI Bluetooth® interface lets you stream music from your compatible device, make hands-free phone calls, and control up to four IQ amplifiers in a large system.
Kicker Q-Class amplifiers incorporate cutting-edge technologies and superb construction to deliver an extraordinary musical experience in your vehicle. These amps are only sold by select dealers chosen by Kicker.

Class D Amplifier Design: The Kicker IQ500.1 is a mono Class D amplifier. Class D amps are known for small footprints, as well as highly efficient power plants. The IQ-series amplifiers feature TWEEQ tuning software, giving you the ability to configure your amplifier exactly the way you want with a PC or tablet. Kicker's IQ-series amplifiers carry a 3-year warranty.
CEA-2006 Compliant: The Kicker IQ500.1'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. The CEA-2006B specifications for the IQ500.1 are as follows:
- Power Output: 250 watts RMS x 1 (4Ω, 14.4-volts, 1% THD)
- Signal-to-Noise Ratio: -80dB (1W, A-weighted)
Kicker Power Output Specs: Kicker publishes the following power specifications (14.4-volts, ≤1% THD+N):
- RMS Power at 4Ω: 250 watts RMS x 1
- RMS Power at 2Ω: 500 watts RMS x 1
Kicker Livin' Loud Certified Power: The amplifier comes with a certificate that indicates the total maximum wattage of the particular amplifier, along with the model number, serial number, and whether the amplifier passed the total harmonic distortion, signal-to-noise ratio, and protection circuit tests.
TWEEQ Tuning Software: If you don't want to be limited to just the on-board controls, the IQ500.1 lets you connect your PC or tablet for a wide range of audio processing. Kicker's TWEEQ DSP software offers a 31-band EQ with +/-12dB adjustments, 24dB per octave crossovers, digital time alignment and phase options for all connected speakers, a full limiter/compressor, and an input mixer. A simpler option lets you choose the speaker size, location, and channel information, and let the software do the rest. Download the TWEEQ application to your PC (Windows 7, 8, or 10), connect it via USB (Mini-B USB cable required), and start exploring. With the optional Kicker IQI Bluetooth interface, you can use your iOS (8.0 or later) or Android (4.0.3 and up) tablet or phone to make your adjustments wirelessly. Up to 4 amps can be controlled with the IQI interface.
Subsonic Filter: The Kicker IQ500.1 features a built-in subsonic filter that cuts ultra-low frequencies that cannot be cleanly reproduced by a subwoofer. These frequencies create distortion, waste amplifier power, and can cause damage to speakers. The 24 dB/octave subsonic filter is fixed at 25 Hz.
IQRC: The amplifier comes with the IQRC Remote Bass Level Control, which allows you to control up to 2 amplifiers from the driver's seat, even though your amplifiers are in the trunk or under a seat. The IQRC gives you the ability to adjust the gain (-26dB - 0dB), bass boost (0dB - 18dB), center frequency (24Hz - 80Hz), and bandwidth levels (0.5Q -10Q) for up to two matched amplifiers. The IQRC is 2-11/16"W x 1-1/2"H x 2-1/4"D, and comes with a 16-1/2' flat cable.
Auto Turn-On: The 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).
- Audio: The amp turns on when an incoming audio signal is detected.
Note: In the DC Offset and Audio modes, the amp's remote terminal acts as a +12 volt output to turn on another component.
Failsafe Integration Technology (F.I.T.): Kicker uses a special circuit for the audio input called Failsafe Integration Technology, or F.I.T. This special input circuitry lets you connect factory or aftermarket head units to the amplifier simply and without noise. Because of F.I.T., Kicker recommends using speaker-level inputs whenever possible, because it's a cleaner, stronger signal. Optional Kicker KISL speaker wire-to-RCA adapters make it easy to convert your head unit's speaker level outputs to RCA plugs.
Protection Circuitry: The IQ500.1 has protection circuitry that will turn the amp off in the event of overheating (thermal), over voltage, under voltage, and over current. There are separate red LEDs on the front of the amp that illuminate when the protection circuit has engaged. This helps you quickly identify and correct the problem.
Amplifier Stacking Kit: You can stack two IQ-series amplifiers with the optional Kicker IXSK Amp Stacking Kit. The kit contains the hardware necessary to vertically stack two IQ-series or two IX-series amplifiers.
Gain: To accommodate the varying range of signal levels coming from today's factory and aftermarket radios, the Kicker IQ500.1 features an adjustable gain control (low level: 125mV-5V; high level: 250mV-10V). 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.
Input Level: This 2-way switch lets you select the input type. You can choose Lo or Hi input.
Low Pass Crossover: The amplifier's variable low pass crossover can be set between 40 and 180 Hz, with a slope of 24dB per octave.
KickEQ Bass Boost: The KickEQ bass boost circuit provides a variable (0-18 dB) signal boost at 40 Hz.
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 Allen-wrench is required to tighten/loosen the terminals.
Note: The recommended gauge for the power and ground wires is dependent upon the length of the power wire. For runs up to 19 feet, 4 gauge wire is recommended. For wire runs of 19 feet or more, 1/0 gauge wire should be used.
Fusing: The IQ500.1 comes with a Kicker AFS fuse holder with a 60-amp AFS fuse installed. This fuse should be installed within 18" of the amplifier. A second fuse should be installed on the power wire within 18" of the vehicle's battery. The fuse rating of the battery fuse should also be 60 Amps, or, if more than one amplifier is connected, the sum of all the external amplifier fuses.
Speaker Outputs: The Kicker IQ500.1 is equipped with one pair of set-screw speaker terminals that will accommodate up to 8-gauge wire. The supplied 3mm Allen-wrench is required to tighten/loosen the terminals.
Input: The amplifier is equipped with one pair of RCA inputs that will accept line-level or speaker-level signals. When a speaker-level signal is used, a speaker wire-to-RCA adapter, such as the Kicker KISL, 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 full-range stereo 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.
IQI: The optional Kicker IQI Bluetooth Interface connects to the amp via this proprietary, multi-pin connector.
