Ratings and reviews

Good at first, I bought the AX-DSP-XL in April of 2021 worked fine w/firmware 2.1 then in December of 2021 there was an app update and that's when it went bad, I lost DSP control everytime I'd open the app all settings would go flat & can't save settings and couldn't get sound if I selected my vehicle type I had to select "General". Tech support and kept saying it was my Note 10+ is why it wasn't working then as of Jan 26 2022 update w firmware 2.7 & I have sound, no saving. It's an app issue.

At first it seemed to work, understanding it was a learning experience for me. Since installing in the spring of 2023 it has progressively gotten worse and quite frustrating. As of this moment (September 6th 2023) I can't even connect to it (2 days now). It has been cutting out for a few minutes at a time (even with cold amps) multiple times a day. At times it seems to lose the settings I installed. For the price tag this thing should work flawlessly. Not very happy!

I think the DSP itself is buggy. On my 2017 Expedition, once a day or so my left front channel will cut out. I have to reset settings to default and then redo my vehicle type and EQ settings. Every couple days, when I start the car the radio is super loud and I have no volume control until I reset the vehicle type again. What a pain. But when it is working right, the sound is awesome.
