Well worth the money. This gives me full control of my music on my Goldwing. Small light weight and the App on my phone is priceless.

No fault of product, it does what it's supposed to do. Used for 2 weeks, no complaints on performance, but purchased another dsp from a competitor because of more functionality and it was actually cheaper. My only complaint is it that tuning is done thru app only. I would prefer the app AND a PC based program. There's alot going on and a PC program would have made it a keeper.

Good quality and good sound make this a great item. It does everything it says it will. Being waterproof is a great making it excellent for motorcycles, ATV, boats etc. Just a great product. :)

Sadly, no matter what I did this DSP introduced clipping to the signal. It showed this clipping on the unit itself and I verified with an SMD amm1 and a o scope. My input signal was verified clean going into this unit I tried to lower the master gain input gain output gains nothing helped spent hours and could not get it to not clip the only way to get no clipping is the lower it so much that the preamp output voltage was like .2 Volts. It’s too bad because it’s a nice looking unit and the app is excellent, but unusable with all this clipping.

This sound processor makes a big difference in my polaris slingshot sound system. The best thing is that installation is easy, and I can control it with bluetooth unlike other brands. Also, since it's water resistant, I still can wash all interior of my slingshot with water and nothing happens.

No matter what I did the audio using this was horrible compared to not using a dsp at all. Even with no eqs adjusted or any adjustments whatsoever the audio output sounded realy bad. Went back to no dsp and sounds great again.

This was installed on my Harley street glide. Those who rides one will know how hard and troublesome it is to remove the fairing. And the speaker sounds different with and without the fairing on.As such, this little DSP is a must for tweaking. Coz the tiny knobs on the amps are almost impossible to get it right.So all you need to do on the amp is to set as Full Pass. Set the gain to aprox level or using a multimeter… and use the DSP for the fine tweaking.As this is my first experience with a DSP, it’s good enough for me. Nothing much to complain and it’s easy enough to use with some knowledge of audio set up.Note. It’s a very basic DSP but has some of the most common functions in there. Refer to the image.
