To check your low level (RCA) clipping point. Connect leads to your rca output and follow same instructions
In this video I show you how to check the clipping point to achieve the maximum un-distorted volume point of any head unit. Using this method you can do it by ear using a low test tone on a door speaker. Or using an o scope with any frequency. I have a video on my channel describing the $40 oscope i used in this video. Check it out to see how to use it to tune your amp.
If you want one of these, just search online (eBay/amazon/etc) you can find many available under $40.
