SoundStream BX-20z Digital Bass Processor

Took a little fiddling, but this $60 DSP made my 10-yr old Infinity Reference 12s come ALIVE!2007 Ford Crown Victoria P71 Interceptor, JVC double-din head unit, hybrid front 5.25" component set, Rockford Prime rear component set (wouldn't recommend aside from easy install), DB Drive 1050 monoblock, 3 Infinity DVC 12s in a 2.6ohm loop.Setup; I set sweep about 15% up (30-35hz), wide set about 1/3, amp gain maxed, amp bass boost all the way down, amp crossover set open (max), subsonic filter set open (minimum), bass boosts/effects on head unit off, and head unit equalizer set to flat at 60hz and -3 (of +/-9).To "bypass" this DSP's subsonic filter, turn the right dial all the way down/counterclockwise and leave it pressed in. From there, the left, bass control knob lets me easily adjust the bass up to and back from distortion.With three 10+yr old 12s, it's now loud enough to make my ears ring when I get out. And my hearing isn't the best by far! I highly recommend this over the $25-40 ones on the market for it's adjustable preamp voltage setting and dual grounding alone.Read full review...

Set your amp correctly, then use this bad boy to crank it up even more, thank you !

It sounds way better I recommend it it’s worth it

Unit made a night and day difference on music with minimal bass, Oldies and old school music, R&B. With rapp music, had to turn down the bass knob, sounded distorted. It brings out all the bass you lost when converting to mp3 mp4 format. If you like music that you can feel, I would recommend to add this to your system.

I had the Sound stream epic center installed with my hi fonic 1,000 watt Amp. & 15" L7 kicker and it makes alot of difference im glad I bought it ????????????

I love it, I turn that knob all the way up and my neighbor hates me.

This is a much needed item easy to hook up and it makes ur system sound great

I received it and went to wire it up just how it showed in instructions and when it tried to power on it killed my amp and Capacitor. I do not recommend getting this specific one.
