So a friend let me use his SMD DD-1 to determine where my stock head unit starts to clip. It's a 2022 WRX Premium and with a 40 hz tone at 29 the clipping indicator flashes ( at 28 it flashes once only ). With a 1khz tone it does not detect clipping even at full volume. Is this normal? I assume 28 would need to be my max volume level so I can set my input gain on my V Eight that I'm using to integrate with. Side note: I will be using LGD-20 from Audio Control so I wont get an error from my StarLink module for not detecting a speaker connected to it, should I re-test after the LGD?

Yes retest after the LGD-20 is connected, then take the average clipping of 40Hz and 1K Hz. What is he max volume level of your headunit?

You could also turn down the sub/bass level on your head unit till it doesn't clip 40hz at full volume then set gains at full volume. Just a thought.

Yes this is normal in most modern cars. use 28 as your max volume.

No need for them. If you have a Helix V Eight Mk2, it has ADEP.3 built in. It is a smart circuit that detects OEM load requirements and applies the necessary load.

Thanks Nick, wasn't sure the V Eight would have the right circuitry or not. That'll save a little bit of work at least. I'll be using 28 as my max point, thanks!
