[QUOTE="UNBROKEN, post: 104145, member: 24"] Can you even comprehend that by having the amp gain all the way up, then overdriving it with a clipped signal from the head unit THAT is what causes distortion and damage? That's not my opinion, it's not anyone's opinion....THAT is a fact. Everyone in the car audio world except you seems to be able to understand this. Let me try another way....or again....whatever... The head unit, ANY head unit at some point on it's volume scale will send a clipped signal. An amplifier amplifies, this much we can all agree on. Say you like to crank up your stereo, I know I do....if you crank it to max volume you ARE DEFINITELY sending the amp a clipped signal. If you have the gain cranked up all the way you WILL be amplifying that clipped signal....period. It's fact and not open for discussion. THAT is what will cause damage. I'll use my head unit as an example. A Clarion DRZ9255....most people have never even seen one but trust me when I say it's well regarded to be among the 5 best head units ever produced by anyone. It's specs are off the charts and 99% of end users would never need even 1/2 of what it's capable of. It's one of onl,y 3 head units ever made that will do 4 way active without external processing....if you don't know what that means then I'll stop replying because my words will be pointless. Anyway...it sends an 8 volt signal out at max volume which is very high as most are in the 2-3 volt range. Now....my amplifiers will accpet that input signal where many will not. By setting my gains with a digital voltmeter and the math it takes to figure out what the output voltage of the speaker terminals should be it comes out to this: My 150 watt 2 channel to my front midbasses is set at 24.5 volts at the speaker terminals with a 1Khz sine wave My 300 watt 4 channel amp for my midranges and tweeters is set at 17.3 volts with the same 1 Khz sine wave My mono 1000 watt amp on my 10W7 sub is set at 54.7 volts for a 3 ohm load using a 50 Hz sine wave. These gain settings are done with the head unit's equalization set flat...all of it. The gain settings ARE the set it and forget it part you talked about. Further tweaking to levels can be done after you maximize the UNCLIPPED signal coming from your amplifiers. Cranking the gain all the way up is so wrong it's not even funny. By doing it this way with your head unit volume at 3/4 way up you still have some leeway to crank it up without sending clipped signals down the line to the drivers. Tweak at will....AFTER you set the gain structure correctly. This again is not my opinion....it's a fact of car audio. Anyone reading this would do themselves a favor by reading up on proper gain setting techniques. Not only will your equipment thank you but your whole system will sound better once you back things down to below their clipping level. And here's a hint...if it's still not looud enough...you need more power, not more gain. [/QUOTE]
