Great amp for multiple channels in your car. If you have tweeters in a location that would make it a nightmare to run wires from the mids, such as dash located tweeters and door located mids, this amp basically solves that problem. You can then go ahead and set crossovers and, better yet, time align each speaker perfectly. I have it running 6 channels in my 2015 Nissan Xterra (dash tweeters, front mids, rear doors), and then I have a sub in the back. My only gripe, as mentioned in another review, is the lack of an RCA out for a dedicated subwoofer. It's great you can tune everything in the app, but then you're hung out to dry if you don't have an aftermarket head unit for your sub. One way around this would be using the powered outputs to your sub amp, if your sub amp can handle powered inputs. Just an idea.

Pros: Compact, easy to setup, intuitive app

Cons: Not incredibly powerful, no RCA sub out.

Great amp

This amp is amazing! The only thing I wish it had was an RCA out controlled by the software. The software is very easy to use. A tip I would give from experience is to save your changes often so you don't loose them. The amp is compact and easy to put in many places. I used it on my stock speakers and made it sound amazing.

Pros: The amp is compact and very versatile.

Cons: I wish it had a programmable rca out.
