Whats wrong with turning the gain up all the way

so buying a 1200 rms amp and setting it at 3/4 gain is only getting you 900..

thanks homie.//content.invisioncic.com/y282845/emoticons/veryhappy.gif.fec4fed33b4a1279cf10bdd45a039dae.gif

man, i'm trying to be serious here. You said i will gain 3 or 4 db, well if thats the case then how much louder would that be?

 

[gunz4me 10+ year member]

Where did I say you would gain 3 or 4 decibels? Also, even if I did specify a number, such as 3 or 4 decibels, guess what, your system would be 3 or 4 decibels louder!

dec * i * bel - [des-uh-bel, -buhl]

–noun Physics.

1. a unit used to express the intensity of a sound wave, equal to 20 times the common logarithm of the ratio of the pressure produced by the sound wave to a reference pressure, usually 0.0002 microbar.

2. a unit of power ratio, the number of units being equal to a constant times the logarithm to the base 10 of the intensities of two sources.

3. a unit used to compare two voltages or currents, equal to 20 times the common logarithm of the ratio of the voltages or currents measured across equal resistances. Abbreviation: dB, db

after going threw this thread i have thrown up and gone to the bathroom on my self. some of the bs just makes me sick im not gona even say what i think about the gain issue ill pass.

read the first page. to op, volts x amps = watts. and everyone else who doest know how to set gains check out the12volt.com please!

Twice as loud... NO! A few decibels, probably. Doubling your output, HELL NO! If you mention anything about 3 dB being perceived doubling by the human ear, I am going to send Vince McMahon to **** the dude in your avatar like he used to do in the good old days!
Cleaner... YES

fyi... double the power=3 dbs roughly... and .... 3=few ... again roughly... good day

The Ultimate Warrior's rectum is quivering right now because of this response. Vince McMahon just popped a Viagra and is on his way!

Why are YOU telling ME this? I didn't specify an EXACT number with certainty and I am sticking to it!

The general rule is doubling the power should net you a 3 dB increase, and I will agree to that. Doubling the power while failing to perform the supporting electrical system upgrades will result in amps that go poof when the voltage drops.

Idk If anyone answered this correctly b/c I saw a lot of really weird answers.. some more retarded than others.. Basically.. Your amps gain is not a watts dial.. It doesn't control how many watts go into the sub.. Its job is to match the voltage from the h/u. Say you h/u has 4v preouts.. your amp setting would be close to fully to the left.. Now then.. If you set your gains to higher than what the h/u is putting out then it will get louder faster and the music won't have much range.. and where it used to be getting to full tilt it will be in clipping area.. I really don't feel like writing a paper on this though.. so I won't

i have to agree with this post, very good read.

Is it so hard to agree with me? lmao.

ZOMG DEBEEZ ARE ATTAKING MEH

Range...? Google "Distorted Sound Wave" and you should come up with a few .wav files that show you what a distorted (clipped) sound wave sounds like.

And while a higher pre-out voltage does mean the gain has to be set lower, I wouldn't say "close to fully to the left," because that's just wrong. 4v is about half way... but it depends on the unit, the manufacturer, the lot, the amp, etc.

And, while we're on the subject of clipping... ALL head-units begin to clip the pre-out towards the maximum volume. For some it begins at ~75% of the volume, for others, it's about ~80% or ~90%.

My Pioneer DEH-P6900UB begins to clip at 50/62, and it actually starts clipping at about 55/62.

The is where having headroom is great. I never have to worry about having distorted power come from my 4 channel amp, because have plenty of power to the point where it'll never be driven to it's limits with the current speakers I'm using. I have my gains all the way to the left, or all the way down. I'll normally listen to my music at 60-65 out of 80 on my HU with it set like this.

Not all HU's clip the pre-outs. I've used an o-scope on my 8053 at full volume(80/80), and there was still a perfect sine wave being produced. That's one reason why I love my older eclipse 8V HU's...
