A meter does not guarantee u clean audio. It's one of various ways to shape the outer boundary of the sandbox u intend to play in thus with ur experience ditch the meter and use ur ears.

I should add that the meter method is to get your gains and target voltage to where you may w
ant it. That’s it though when we all throw around the word tuning it’s more than setting gain. Tuning to me is
setting crossover and equing if you have that ability. Then yes your ears will tell you whether you like it or not. I think metering helps us learn especially for new people simply turning it up till it distorts and back it off may work for some but not all. A lot of people are asked how much are you sending those speakers and then the answer is idk my ears tell me about 150watts!?!?

A DMM does not have the capability to detect distortion. Ur ears do. Just cause the side of the box says 150w x 4 does not mean that ur guaranteed a clean signal to 150w.

I use a 1000hz test tone Disk/CD like I always have before. And yes always set to a/c voltage when tuning the amps on my installs!

Do you have voltage out of the head unit? Check rca leads coming out of Kenwood with dmm.

Yes his Kenwood HU max volume is 35 so we tested it at volume 26 (of course no speakers connected)

Does your DMM have a selectable scale for AC voltage? Maybe it's set at too high a scale?

Back in my E&I days we were instilled with the habit of checking our meter at a 110V outlet often. This is a simple verification step. I still do this almost every time I break out one of my Fluke meters.

Also basic troubleshooting starts at the source is it on? Yes. Does it have power out? Yes/no and so on until we find an issue.

Well I would think we would have voltage out of the RCA's from the head unit as we are getting great sound from the speakers?

NOTE) Even though we upgraded his 2 channel amp to a 4 channel amp he is still only running 2 channels for now the front fairing speakers only so only 1 set of RCA's are being used! the rear channel is not being used at this time.....
