I ordered a oscilloscope from Amazon going to test my gain settings on the 2 SD 800X4 amps then I'm going check the sony ax7000 what volume it clips.

 

Do that in the reverse order. Figure out when the HU clips and then set the amp gains. fastsoup posted this video from YT a few days back. I think it's one of the best on the topic I've seen. Good Luck!

 

Yes I will go in that order thanks for heads up and I should use the1k freq ?

 

I'd be curious to see where they both clip. My 15 cvo stock head unit clipped at 6 bars from max volume at a 100 Hz 0 db. it did fine with the 1K hz tone at 0 db. I use the amazon scope as well.
