No argument that starting out with a clean input signal when setting gains is important but how does using a test tone ensure that? You still need to make sure the HU is outputting a clean signal first. That signal could either be a test tone or music, depending on what method you prefer for setting your gains.
Well the O-Scope can confirm the head unit signal prior to setting the gains with the amp. Tap positive to the center of the RCA & the negative to the casing. I have always been a set audio by ear guy...but with a bike and all the sound it makes when running makes it tricky. I feel that with an O-Scope I will be able to go max, then compare that to the voltage (see what power the amp is actually putting out) and then go from there.

"Why spend the money?" Well, check out 5:10 of the video. Have you tried to clip the alligator clip on the end of your probe to the outer ground on an RCA plug? That inexpensive adaptor might turn out to be handy while you're trying to do the measurement inside the fairing...with the motor running. Most of my oscilloscope use has been on the bench where I had lots of space and access to vises etc. and yet nothing beats having the right attachments for your scope and keeping your hands free for other things. Just my $.02

I totally understand what you are saying, but a 10ft RCA cable solves that...but yes...the right tool for the job is the only way to avoid excess effort.

Will that be the same 10' cable you use between the HU and amp? Probably not. It's nice to know that the cable you've used has no intermittent connection issue which is why you should include it when doing your setup (like you will with the speaker wire).

Getting ready to do a 6 speaker install (GZ YB in fairing - SX 165 Neo in TP & Lowers) & started with my head unit (Kenwood KMRM328BT) and connected my oscilloscope to the RCA leads and I could not get the deck to clip @ a 1khz test tone. I then hooked up the subwoofer out with a 50hz test tone and that didn't clip either?? I then connected the FR speaker lead & ran the 1khz test tone and the oscilloscope showed clipping at 28 volume (35 max).
Could my pre-outs really send a clean signal regardless of volume?
Picture 3 is FR speaker at 27 volume - Pic 1 is 1khz at full volume & pic 3 is 50hz at full volume.

Your scope is not playing tricks on you. The Kenwood 328 HU is clean all the way to full volume with a 1k tone at the RCA outputs.
