Amp turn on delay

Is there a way to delay when the amp turns on. 2015 SGS with stock head unit w/ R F flash, SD 800.4 GZ yellow baskets.
Issue I'm having is, when I turn ignition on and HU is powering up, I get two loud blipping noise from left speaker then right speaker, and then left speaker and right speaker again. Doesn't matter if volume is all the way down or volume up. I always turn the volume down before turning bike off. I'm getting the 12v amp turn on from a 12v accessory wire upper right side under fairing. Power and Ground coming from battery.

Thanks all

I could be wrong but I believe a PAC TR4 could be wired in for that. I had one wired in my previous 2012 UC for a 1 second delay because of a start-up pop I was having.

I don't have enough experience to know if the newer CAN BUS system in the 2014+ bikes works different than the earlier bikes or not?

If you have a dsp, it can delay. No dsp, the TR4 does the trick

Not necessarily. All DSP's aren't created equally. There are some that do not have the ability to delay turn on.

Use an inline time delay relay. Short $.

The PAC TR4 is what I would try because it could be triggered from an unused factory speaker wire. That way if the head unit is turned off the amp turns off as well. Sort of creates an amp turn on lead that the factory head units don't have.
