Very nice unit indeed. I originally ordered a taramps pro Bluetooth dsp and didn't like the global eq one bit (could not tame my focal auditors). I bought this one for the individual speaker EQ and that I should have bought it to begin with. Oh man is this dsp tuning tedious and my units usb port for the pc side did not work. I did find the app someplace on the net but dont remember where I got it. All in all im happy with what I've paid for and I'm still tweaking settings... can't help myself lol. Its worth the money and honestly if the come out with a better unit and more capable software in the 80-150 mark i would buy it. Psa put the app on a tablet and your life will be easier!

After loosing my Zapco PX eq I didn't think I could get anything as good for less than a small fortune. Boy was I wrong. This thing is amazing! It gives you total control over your system. You get an eight way crossover with e high and Q adjustment, time alignment and 31 bands of full range equalization for each of the eight channels. You can also mute and phase each channel individually. There are three selectable crossover types and slopes are aej nd select one of three crossover types and e to useare four channels of low and high level inputs and front rear and center speaker outputs inputs including left and right center channel My system has never sounded better.

Well, it looked good. I am glad it came with a computer connection which is a plus. The sound? Well, its average. I guess most daily drivers would like it. The software it should have come on a thumb drive. It pointed me to a Russian web site, after translating it, this model was not there. Spent 2 days trying to find it...someone on the internet published a location and I was up and running. I see no reason to give it a bad review so, I'll just say....its only worth $50

This little box can completely replace a head unit. Nothing else comes close at this price point. As the other reviewers have said, it includes a: * Bluetooth Audio Receiver * Bluetooth controlled DSP * Line Out Converter * 20w/Channel output amp. * two pairs of RCA inputs * four pairs of RCA outputs (see below) If you are new to car audio, the lack of documentation will drive you crazy. But if you've done this before, basically this unit's architecture is designed for: * Bi-amped front speakers (I ran mine in single amp mode) * Center Channel (optional) * Single amp rears * Subwoofer. The only operational con I've found is that the volume had an inexplicable dead spot about 2/3 of the way up when using the phone's bluetooth volume control. Very odd. But at this price point, I just adjusted the gains to avoid that spot and enjoyed everything else.
