Kicker 42IQ500.4 - 4-Channel Q-Class Amplifier

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 Windows device, that helps you dial in your sound just the way you want it. 

Power and brains

Kicker's IQ500.4 four-channel amplifier packs a 65 watts RMS per channel punch, so you know you'll hear your music loud and clear. You don't have to use any app or software to get great-sounding music with this amp — it has its own onboard tuning controls, including high- and low-pass filters, along with a bass boost on both front and rear channels. 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 on every channel, all there to help your system sound perfect.

More for you

An optional IQI Bluetooth® interface lets you stream music from your compatible device (Windows PC, iOS, or Android), 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.
