## Customer Reviews

### ⭐⭐⭐⭐⭐ Dps
*by G***  on February 25, 2025*

Good for the price did the job sounds good

### ⭐⭐⭐⭐⭐ Great device
*by M***S on July 9, 2025*

This is a great little budget DSP. I wasn't sure if I wanted to run a DSP because I thought it would add unnecessary complication to my system but I was wrong. I bought this to try out to see if I liked it and I love having the control it provides, I can't imagine not having one now. It's been installed for about a year now and I've had no hiccups or issues with it. Tuning by phone app, laptop, or the provided controller are all ready to use and user friendly (I prefer tuning via BT from my phone). I'm sure there are better out there but this being my first one, I don't know what I don't know and I'm 100% happy with it.

### ⭐⭐⭐ A good DSP but you'll want something better
*by A***R on August 13, 2025*

The item does as its described. You get a software that's pretty feature packed and gives you access to the features you need. I particularly liked the ability to EQ each channel independently. My reason for 3 stars, however, is that I get some static noise, REALLY LOUD, if I hit a bump on the road. Can't tell if it's RCA related or something else. Sometimes, I turn on my vehicle, and the DSP does not turn on. I have to turn off the vehicle and turn it back on for it to turn on. Lastly, it's introduced alternator whine into my system that I didn't have before. It's a great value for the money, but ultimately, I may end up upgrading to something else with better build quality and sound quality. I reached out to support about my issues by the way and all they sent me back as a response were wiring diagrams, so they weren't helpful.
