Review: Great DSP at a budget price - Purchased this because I wanted to retain my stock head unit but I was having some gain balance issues and couldn't get the sound stage centered like I was used to with aftermarket head units using time alignment. This is going to a 4ch amp powering my door and dash speakers on the front channel (factory wired as 4ohms) and a bridged 10in subwoofer After working with the time alignment I am a lot more satisfied with the imaging. Because of the way the speakers are wired I'm still dialing in the time alignment but I've got the band singing to me from the hood. I also had some balance issues with the head unit making my left side quite a bit louder than the right. Using the individual channel gain controls I've got that issue under control. The included crossover points are infinitely adjustable so my front speakers are better matched to what they can actually play. The preset EQs are a great start and with some more fine tuning I should have this dialed in. If you're amping a factory head unit I STRONGLY suggest buying this so you can overcome the factory tuned EQ curve and bass rolloff Very easy to connect inbetween my amp and head unit, just run a bridge wire over to your amp +/- and remote. If you're using speaker level inputs and your converter voltage is turned up you MAY have issues with the unit not powering off as I do. At this point it's a small draw and I probably need to tap a different line on my converter's remote wire but that isn't a fault of the unit, but it is something to watch out for as idk how many amps it's pulling. At the moment it may just be the blue led, time will tell.
