[QUOTE="n2audio, post: 8363851, member: 540940"] No - there's not. We want the power out of the amp to be close to clipping when the HU is close to clipping. There's no reason for it to be any more complicated than that. We're measuring AC rms voltage. Do this with a tone and any functional DMM it will work out just about perfectly. It is ridiculous that some people on this forum want to elevate setting a gain to some sort of precision laboratory project. Great is subjective, but adequate isn't. The DMM method is certainly adequate. Personally, I've been setting my gains by ear for years (and years), but a DMM and a test tone is all it takes for a total amateur to set a gain with plenty of accuracy to keep the speakers/subs from seeing excessive clipping. If by "a lot" you actually mean "very little", then i guess it's "a lot". Not any head unit I've ever encountered, or heard of. Besides -- so it clips a little...if you can hear at all, and the clipping is bad enough to present a problem at high volume it should be plainly audible. Just reset the gain with the volume a little lower -- problem solved. This isn't rocket science. [IMG]//content.invisioncic.com/y282845/emoticons/eyebrow.gif.fe2c18d8720fe8c7eaed347b21ea05a5.gif[/IMG] I'm curious on how this might come about. To summarize "possible pitfalls" -- essentially, none. [/QUOTE]
