Arc Audio PSM Digital Signal Processor

[Stl-BooDog]

I'm thinking about upgrading the sound system on my 2017 Street Glide Special.

I've already decided to go with the Arc Moto 600.4 amp. I'm looking at adding the PMS Digital Signal Processor. Has anyone used this unit, what are your thoughts on it?

Whatever input will be greatly appreciated.

I did it with the 600.4 amp and focal speakers. Originally did the system without the PSM which I only added about a month ago. I was skeptical about whether it was worth it or not but it did make a enormous difference and I was very happy.
