Do pretty much all head units send out a clipped signal at 3/4 volume? I remember reading something about 3/4 volume and never pushing the head unit to 100% volume...

Also, if that's the case why don't manufacturers limit how much you can crank it (if possible?)

idk if thats true but i always assumed the same thing bro on my hu seems like it distorts at 33 out of 35.

No, thats just a good rule of thumb to help avoid it.

O Scope would be the only way to know 100%.

Damn. I wish I still had an oscilloscope. :|

Don't plan on calling on asking the company and ask if the head unit clips at 3/4 volume.. they will tell you it does not clip.

In my dodge ram the kenwood clips at 33 out of 40 i believe

Keep in mind that most high volume manufacturers design their equipment for a wide range of uses. While the unit may clip at 75-80% of maximum volume with a 0db tone, it won't with a lower level source......which gives the HU some additional "headroom" in it's volume range when used with lower level sources, such as radio or quieter music. So just because a HU clips at less than full volume, it doesn't make it "bad", just designed for a different range of consumer uses.

Asking the question "does this headunit clip" to a manufacturer is a little vague.....it all depends on the various setting and source material. That's like asking an amplifier manufacturer if their amps clip the signal.....sure they can, they all can, it's just a matter of when and why, or under what circumstances. Just like with an amp, different settings (such as boosting the treble or bass controls, or EQ bands if the HU has them) will cause the unit to clip earlier in it's volume range (or cause a unit that doesn't "clip" with a 0db tone to start clipping the outputs).

And as mentioned......no, not all HU's clip at a given volume setting. But they all can, depending on the use.
