Review on 🚗 Car Amplifier Subwoofer EQ Crossover with RCA Line Level & Volume Control by Andrea Sloan

I used an old subwoofer on my computer and didn't want to use the subwoofer on my sound card. So I just split the left/right main out and sent one channel to the subwoofer. It works fine, but the sub doesn't have its own crossover. This little box fixed everything. No more dirt. Good tight bass and remote subwoofer volume control (gain). Works perfectly. No distortion at all. I'm still shocked that it's in a nice sturdy metal case. It's well built and works great. Almost something from the 70s.
