AudioControl EPICENTER Digital Bass Restoration Processor - Car Audio Bass Booster with Wired Remote (Black) | Enhance Low Frequencies for Deep Bass in Vehicles, Trucks & SUVs

This device does what it says it does. You can of course over do it. You do not need to turn the knob all the way up in order to feel like you are getting your moneys worth. You can leave it low. I never turn the knob above 50%. This device does a FANTASTIC job of recreating bass in tracks that do not have it. I was extremely skeptical. I thought that there is no way that they could just realtime add bass and it would sound nice. I thought that there would be timing issues or some detectable disgusting artificial quality to the audio that it was generating. I was wrong. I decided to get this thing due to the overwhelming support I see in the build community for car audio.When I was installing this my wife was completely convinced that I was an idiot, and I was not sure myself. She said. "So its just gonna add more bass" and "why does everything need to be all WHAAMP WHAAAMP?" etc.Following the install I handed my wife the remote, explained that is was NOT a volume knob, and we drove around and played all of her music while she adjusted the knob to her liking.My wife now wants one of these in her car, and in the house.It brings every song that was mastered terribly in the 50s 60s 70s 80s and even Now into the full spectrum for playback on the system that you've invested so much in. It completely changes your relationship with music that you've known so well over the years.This product is ridiculous, I love it, it works, It sounds great, and it 180'd my wife from hating the idea to absolutely loving it due to what it does to her music. (My wife HATES/used to hate) bass) I think that says enough.
