Tweeter question.

i have set multiple amps with a dmm it just doesnt make much sense to me that turning the gain knob "up" results in a smaller amount of output, because whenever i raise the gain the voltage always rises

And lowering gain lowers voltage which in turn relates to the power the speaker sees.

alright then so how do you propose raising the gain would result in "dialing down" the amp lol

You dont. You lower the gain.

then why did you tell him to turn it more towards .2v when that is raising the gain? ffuuuuuu

with the deck im running i have sent amps into clipping with the gain all the way down.

only way a can limit the power that something puts out is to adjust it back with the headunit.

but back on topic...

How did you test for a clipped signal?

an o-scope.

also the fact of almost blowing speakers with well less than their rms

double.

Thats funny because you cant blow a speaker by using less power than RMS unless your clipping it.

Thats his point. He knew the amp was clipping based on an o-scope and the fact that he was blowing speakers with power levels below their rated rms, which you just said is only possible if the amp is clipping, which apparently it was.

it was clipping.

i was noticing that my mids at the time were starting to get stinky with less than rated so i had it checked with an o-scope and it was a clipped signal.

moral of the story is i need 4 tweets that will take 100rms. and i prefer silk domes.

And you dont see an issue here? Turning the gain down should never cause a clipping issue unless something else is messed up.

your not understanding the simple fact that when the gain all the way down is only set for a 6v preout and the deck im running has 6.5v preouts that it can cause clipping.

but i got my new tweets. which was the whole point of this thread sooo.

/thread.

that's what i've been trying to explain...

turning the gain knob clockwise increases it, counter clockwise decreases...but when 6v is fully counter clockwise you cant turn it down anymore than that. only way to turn it down would be if the amp accepted a minimum of 8v not 6v
