The Kicker ZX 150.2 is part of the ZX Stereo Amplifier line. The line goes from the compact 50-watt model all the way up to a 425 watt one. The Kicker ZX 150.2 is smaller, lower power item in the line with 75 watts per channel (or 150 watts if used as mono instead of stereo). With a built-in 12dB/octave high-, low-, or all-pass electronic crossover variable, the Kicker ZX 150.2 is a good option for anyone wanting a stereo system with a compact size and a decent amount of watts. The KICKEQ Boost that comes with Kicker stereo systems offers 18 decibels of bass centered at 40 hertz. The Kicker ZX stereo series also comes with some automatic turn-on modes such as DC Offset which detects surge from hi-level speaker outputs.
