I am using factory amplifier and optical decoder box. When system starts and turns off. Sub makes a very loud sound. Any one resolve this?
Speaker Amplifier Sudden Thump/Bass pop at ignition on and off
Is there a separate dsp and power amp?
There's a current surge sound at startup and shutdown, most likely caused by an aftermarket dsp or power amp.
it is a mercedes w211 with harman kardon sound system. the optical decoder box is plugging and sending sound directly to the oem amplifier.
I tried plugging in an input into the box from an external source. I had my phone to rca directly to most box and have the same issue. Whats your situation?
I have the same problem using a Helix M6 DSP amplifier. Loud pop when I shut down the system. I use Dudu7 headunit.

Same problem. 2017 wrangler with the factory Alpine stereo upgrade/amp/sub. Loud pop on start.
Same problem here. Toyota Camry XLE 2005 with JBL amp, Hiworld Canbus.
I just installed dudu7 yesterday Subaru outback 2017 with OEM Harman kardon amp.and speakers using simple cambus and I am experimenting this exact same problem o happy about getting. This loud pop worry my speakers or amp.could get damaged. Can you share the solution to this .
After DUDOS3.6 update I started having issues, so far the most annoying issue is the pop sound when turning off my vehicle. Before the update the sound worked with no issues.
2015 Sonata Limited with OEM amp (JBL)
IF I move the Car volume to 1, it will not make the pop sound, but then I won't hear anything.
Any suggestions?
