After along time of installing my set up. I about to embark on setting up the amp for the first time. Now, I have researched this and understand it pretty well. However I have a question relating to this and running speakers in.

All the guides I have read have said to set the head unit volume first with the amp gain very low.When I hear distortion to back off the volume to the sound is good. Then on with the amp gain and do that, I understand this however my friend told me not to go over 50% volume or gain so as not to damage the speakers.

How can I set up the system without going over 50% volume on the head unit or 50% gain on the

amp?

Is it acceptable to set it up going over 50% and then reduce it for a few months till the speakers are run in or is the 50% an absolute must?

Thanks

pretty much no sense. i mean its not a bad recommendation but its not accurate information. most CD players will clip around 3/4 full volume. some way earlier. like that ****** alpine 149.. if you don't have a way to test output its a safe bet not to go past 3/4 volume and set hte gain according to the input from the source unit.

when you hear distortion back down at least 4 clicks. chances are you are hearing 20% distortion..

 
Thanks again for your advice:)

So your advice matches hat I have been reading about.

But do you agree that the amps gain on any channel shouldnt go above 50% in the first few months. Or is that overkill.! Sorry still a bit confused!

if your CD player has a 4 volt preamp outputs turn the gain knob to the 4 volt make and you will be fine.

 
If your amp is like most it accepts up to 6v. If you have 4v preouts that mark is around 1/4. If you have 2v preouts it's around 1/2.

50% gain isn't 50% power.

Check your amp and see what's the highest input voltage it accepts. Then check your HU to see what's it's preout voltage

 
most modern head units go up to 90 to 95% without clipping or distorting nowadays. that 3/4 rule is for old crappy head units that actually distort. Every modern head unit i've come across is clean 39/40 or clean at max volume.

That's what I figured too but look into the Alpine high-end units. 1.9 volts poo..

Oh god a Rockville. And JVC.

8v in 2.5v out. A hair over half gain will be close. I wouldn't even chance trying to get full power out of it. A bit to much and dirty dirty. Smoked speakers.

Or anything a hair over half gain and its asta la vista set up?

No it don't work like that. If you have 2.5v preouts and you run the gain past 2.5v that's over driving the amplifier, dirty power, burnt coils, wasted money, frustration. It's got nothing to do with months. Once the gain is set it don't move unless to back it off.

SQ is subjective. If you're looking for the flattest possible response curve, usually sealed will give you that in a car. Porting is more...
