Whats wrong with turning the gain up all the way

[Jakeeck 10+ year member]

i have my 15" IA LI 4 ohm dvc wired for 2 ohms on my hifonics 1208d.. so it should put out 900w at full gain right? well the gain is like 3/4 of the way up so im getting 600-650.. whats wrong with turning the gain all the way up so im getting 900?

ur an idiot that should have had gotten a bestbuy install

the end!!!!!

get ur gains set, go to a local shop, i dont feel like explaining

i installed it all myself fine

sweet thanks for the help guys.

I know someone that has 2 sony xplod 400 RMS 2 channel amps, each amp is bridged and wired to a 300RMS 10'' at 3ohms and the gain is turned up all the way up and nothing has blown up and its been over a year like that.

i used my mtx 2300x at full tilt never had any problems, i used my orion 2500d's (4 of them) mostly at full tilt and never had any problems... i just know how to burp them at the correct volume (way lower than if i had the gains set lower of course).

the correct way is preferred but if you want to try it your own way then by all means do it and the best of luck to you.

congratulations on a neat story, could you tell me that again one day?

correct me if im wrong but more gain=more watts right?

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

ive heard from many people its a bad idea to turn gain all the way up.. i just want to know why

Most the people who are just bashing you don't kow the answer to this question so that just write "fail" but Its a honest question. I'm sure someone who actually knows will chime in..

becuase xplods are the ****....

they were built with integrated flux capacitors //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

If the gain is not set correctly for the impedance load and the input signal the amp will start to clip really bad. With my last statment I was just proving a point that it depends on the set up.

Turning the gain all the way up can cause clipping, which can kill your sub. There is your answer as to why you don't turn the gain all the way up

 

[steveBeatz]

You say it CAN cause clipping, well maybe you can inform him how to turn it full tilt without causing it to clip ?

Nothing is wrong with it if you have such a low input voltage that it needs to be set that high.

Incorrectly or improperly turning the gain up all the way isn't a great idea, however.

Apparently you don't know it either.

--------------------------

The gain setting on your amp is only there to match the amplifier with the output voltage of your headunit. Once that is set correctly, increasing the headunits volume is what will be increasing the amplifiers output to your subwoofers. If you have ur gain "maxed" (set at the lowest setting, like 1.0v) then if ur headunit is putting out more than 1v, say, 2.5v, you will clip your amp long before u max your headunits volume.

In a nuttshell.

Well rethink your answer there. It's not clipping itself that kills a sub. It's the increased area under the curve because a square wave has more area than a sine wave. So it is actually the additional power that is killing the sub, because that extra power might end up over driving the sub past it's physical and thermal limits.

i'm going to run my Jensen amp at full tilt @ 4 ohm on my HCCA 10, it is a 200w rated amp, I have a strong feeling that it wont ever blow the sub //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

btw no if you turn your gain up 3/4 of the way you wont necessarily see 3/4 of the rated 1200w aka 900w

Lol you're a quick one, I don't and never said I did, is there a problem with that?

There's nothing wrong with it at all.

No.

Where the gain is set really doesn't make that much of a difference - the whole point of having adjustable input gain is to accomodate a wide range of line level voltages.
