works, sounds fine. not better or worse. does it's job.
at first caused a ton of distortion on my subwoofer. so i turned the subwoofer levels all the way down. before i just had an aux to rca plugged into my phone. seems this is a high voltage output. set my subwoofer to high voltage input and set the volume all the way down. this thing works pretty well. confusing a little bit on the fader. not sure how i'm going to find the center point exactly but my left and right subwoofers have additional bass knobs so not too hard to figure out. i needed something to control the frequency of my rear subwoofers dynamically and volume. the additional channels for 2 more subwoofers is perfect for my under seat subwoofers that are on the way. since they are exactly the same they can run on the same volume knob. this thing fits perfect wedged between my seat and center console by the gear shifter. volume knobs are both on the end so no guessing while driving just reach down and use. using only 12v battery i think the 30v minimum and maximum is a typo. on the device it is printed 12+ and i can confirm 12+ works fine. as for 30v i'm not sure. probably not. got warm with 5 minutes use under 12v. this thing will definitely convert your low power aux cable from your phone into a high voltage input so beware of that. it will sound worse until gains are adjusted. in some cases this might not be a fit at all for you not sure. in most cases you will keep it mostly low about 5-10% volume. only need to kick it in for songs that are really quiet like studio quality vs. something that is meant to rock every speaker like e-40 my s*** bang. can't comment much on top end quality as i just wanted to boost the low end for my subs.
