Review on 🔍 Enhanced SEO: Power Acoustik PWM-16 Pre-Amp Equalizer, in Standard Packaging by Billy Stull

Works - I use it on my boat in place of a multi-amp head unit for internal speakers, tower and subwoofer. The only downside is that it splits the volume between the subwoofer output and the other outputs. A bit clumsy, but I did it by selecting everything and just using the volume on my phone instead of the "connected" volume control. Otherwise, unplug the power cord and the subwoofer will continue to run at full volume. A small point of criticism.
