Meh at best.
Installed the DSP today. When I adjust crossover for sub it never saves. If you touch the EQ to boost low frequencies it cuts them out altogether. There’s no selection for 2022 Honda Accord or Sport Hybrid. Had the unit professionally installed, and it barely helped. Definitely not worth $400. The app is okay, but as I said, it doesn’t save frequencies. When adjusting crossover it says be sure to lock down, but you you have to back out to lock down, so it doesn’t save the setting.
