I have installed Mmatts in fairing and lids. Stinger amp connected to Dayton 408. I am using the low level inputs to the 408 from the radio. I used the 1st 4 of the 8 outputs from the Dayton to the front/rear inputs to the Stinger. I have no control from the amp. It is not amplifying; adjusting the gain or sensitivity has no effect on the sound. The amp is powering up as the blue light is on. It appears as though the signal from the radio thru the 408 to the amp is not being effected by the amp.

 

This is a pic of my setup

 

Should I be using these:

 

Where is your turn on switch on the dsp set? And how are your rem wires ran? ( Should be 12v switched to rem in on dsp, then rem out to the amp) Have you assigned input channel to each of the outputs you are using on the dsp?
just a few things to look at.

 

Can't tell from the pic how you have it wired but since you're using the stock radio you should have the speaker wires from the HU connected to the harness on the DSP. set the switch to speaker input. Then use the RCA outputs from the dayton to the RCA inputs on the amp accordingly. The remote in wire on the DSP should be connected to the accessory plug from Harley that plugs into the bike on the upper left side under the fairing. The remote out of the DSP should be connected to the remote in for the amp. Once all is fired up, on the DSP screen on your phone go to the mixer tab and make sure they're turned up..

 

Thanks for all the inputs. I believe most of my issues is understanding the DSP. I'm at work now but will get back at it tomorrow.
