Review on 🔊 Enhance Your Audio System with Soundstream BX-20Z Digital Bass Reconstruction Processor by Sean Lafond

Connected. The quality was poor and the power plug popped out on its own until I tied it back in place. It has 4 pins, two on the remote and two on the box. two on the box might have changed the sound a bit? The two on the console did nothing. What's most annoying, however, is that the subwoofer's volume didn't change when the music volume was changed. Turn the radio down, the deep subwoofer was too loud, turn the radio up, the subwoofer stayed the same. Plug the subwoofer into the INPUTS and nothing changed. I don't know what this thing is even supposed to do. A cheap generic speaker found in an old car, the speaker level to line out converter sounded much better and actually worked.
