HifonicsZeus Digital BASS Enhancement 12in. x 9.5in. x 3in.

Still playing with settings, and learning the features but holy crap does this thing add quality to your final output...My current setup (In a 2012 BMW M3 2 Door (e92)OEM Head Unit with Premium Logic DSP Sound. 9 OEM speakers. I believe 2 Coaxial Door speakers, 2 Door Tweeters, 2 underseat shallow mount 8" Subs, 1 center channel in dash woofer.Added:1. Audio Control LC2i Line Output Converter/Line Driver w/ Optional Dash Remote. (To prevent Factory Bass Rolloff, and prevent loss of sound quality from Going from High to Low Voltage.2. Hifonics BXIPro Bass Enhancer w/ remote3. Pioneer 2400w 1 Channel, 1 ohm stable Class D Mono Champion Series Amplifier4. (1) Alpine Type R DVC (4ohm) 12" Subwoofer (Wired in Parallel (2ohms total impedance)5. Ported 12" Enclosure (Approx 1.5 cu/ft)6. 4 AWG Power/Ground Cable, High Quality RCAs7. 2.0 Farad Capacitor...The Wide/Sweep dials on the Unit I've left at around 12 o clock, Where this product shines is on the remote settings, especially the "subsonic filter" you can turn the filter off if you really want to feel the bass, or give it a slight turn to filter any "in-audible" sounds and really focus the subs movement on slightly higher frequency audible notes...This unit is great for 2 things...1) Cleaning up the bass on systems in which an OEM head unit w/ LOC is used or lower quality (128 or worse kps songs) it will process the sound and fill in all the missing information in the sound waves making it seem like your running straight from HQ pre-amp outputs...2) Bringing the Bass out of Music that was originally recorded with little or sub par bass lines...For example, after trial and error with the settings I was able to get some early 90's NWA tracks bass-lines to sound like bass lines from 2015 trap music beats...And thats not even an exaggeration.Also looks great, and seems built very well.

Easy installation sound quality and volume control

I bought this brand because the amps work great, and beacuse"soundstream" let me down twice. but this device didn't, after 1 day of use it burnt or stop working, I returned it and got another one and its working good as expected but the power light doesn't turn on any more, be careful with the installation.

Audiosavings is the name of the company that sold this through Amazon at the time of purchase. I gotta say this worked great for my gmc Sierra 2017 my setup is two kickers vr and Rockville amp I can't really Remember the wattage but it's about 1200 rms note that I do have the Bose speakers on my vehicle. But this really enhanced the bass where it actually makes the bass hit harder on the stock head unit . At first the external knob malfunction but audiosavings gave me a replacement.

Me gusto mucho

Works really good very happy with it

One of the best Bass Enhancer I’ve tried and there are a verity of brands, but this one stands out the sound quality and the function of the nob is easy to adjust.
