IQ Amplifiers

IQ Amplifiers combine the two most import things for great sound: power and control. With a massive Class D power plant and the included TWEEQ™ tuning software, your music can achieve the realism and raw power you crave.

IQ Amplifiers Main


The soundstage is yours to command. The revolutionary TWEEQ™ tuning software is included with every Kicker IQ amp, built to make crafting audio to your exact standards as easy as clicking a mouse or touching a tablet.

IQ Amplifiers Flexible


Designed entirely in the USA, KICKER delivers the ultimate in sound quality and power by hand-selecting the finest components. Paired with an extremely efficient Class D power supply, IQ Amplifiers give you the nuance and thunder with equal ease.

IQ Amplifiers Powerful


The included IQRC remote easily controls your amp volume, bass boost and more with a single cable connection. The optional IQI Bluetooth Interface lets you play Bluetooth audio, answer phone calls and use the TWEEQ software to control as many as four IQ amps, all from your phone or tablet.

IQ Amplifiers Accessible


The IQ500.2 Two Channel Amplifier brings stunning clarity to your vehicle in an attractive black aluminum chassis. A blue LED light tells you the amp is on, and ready to rock! While the amplifier easily connects to nearly any radio in the market, its connectivity doesn’t stop there. With the optional IQI™ Bluetooth interface, your phone can replace the radio as the audio source. In addition to allowing phone voice commands as well as receiving/placing calls, it also allows wireless operation of the free TWEEQ app on your iOS and Android devices. The IQ500.2 delivers 125 watts x 2 at 4Ω and 250 watts x 2 at 2Ω. See below for more details.
