PWM-16 Equalizer

4-Band Graphic Equalizer w/ Built-In Pre-Amp & Subwoofer Control

Maybe you’ve got an older car stereo system that you want to get more from. Or perhaps you’ve got an all-new setup that you want to get the maximum out of. In either case, Power Acoustik EQs will let you fine-tune your sound, along with independent master volume, subwoofer level, and fader controls that’ll maintain your highs and lows in balance.

The PWM-16 features (2) RCA inputs, so you can connect them to your aftermarket system. The RCA outputs ensure that your amplifiers will get a clean, powerful signal for maximum performance.
