Please tell me what I did wrong setting gains

[IgnoreMe 5,000+ posts]

bro think about it this way. you got a left and right speaker. so im assuming you faded to the left to set the gain for the right speaker and faded to the right to set the gain at the left speaker channel...right?

well if you did this, let me ask you something...do you know what the fade does? try hookin the dmm up to the left channel with everything nuetral. then start fading to the right. the dmm will show the voltage dropping for the left channel the more you fad to the right. so where am i going with this?

well since you faded all the way to the right to set the left speaker gain, in a sense you were turning down the "gain" (no its not a gain knob but it acts the same) from the headunit. so you had to compensate using the gain at the amp. now when you went back to nuetral, that 20v that you set to the left channel is now probably somewhere in the 40v area...clipping the shit outta your speakers. clipping = death to speakers.

nah thats not even what killed it. he probably set the gain meaning 4 ohms and it was more like 10 ohms after rise since he left the speakers hooked up....... and i bet he faded right to set right gain

i really hope he didnt. i dont see how anyone can be comfortable setting their gains while theyre listening to their speaker blare out a 1kz test tone...

i can guarantee however, that if he did what i said he did, he clipped it to death. period

he clipped it to death period either way. it's really more of a matter how he came about clipping it. that'd be why oen of the first steps in most gain tutorials is unhook the speakers....

So I decide to adjust the gains on my amp for my component speakers this morning and I was using an 80hz test tone. Between 2 volumes I would get a click in between changing between them. The speaker doesn't sound any different and still plays the tone with the exception of a brief pause for the click. Anybody know what this is? I noticed my amps gain is set all the way up and I'm sure this is incorrect (Strike 121231234591 for the place that installed this stuff). I think this is an amp question based on some of the other posts I've seen about clicking. Help would be very much appreciated, I don't want to hurt my new babies.

not to mention he did it with an 80hz test tone at full balst while the speakers were connected. no wonder they died.

how do you know a 1khz test tone caused his impedance to rise that high? impedance rise doesnt follow rules. at 1kz he might of only got a rise to 1.5 ohms...heat adds to rise as well but maybe he didnt have it playing long enough to get a big jump in impedance.

HAHAH well there you go. i didnt read close enough. an 80hz test one eh hahah what the ****

So next time I go to do this I should unhook the speakers and what's a good test tone to use?

 

[Propimp 10+ year member]

for highs 1khz and lows 50hz

 

[IgnoreMe 5,000+ posts]

yup use 1khz -3db (in my opinion) test tone for our speakers and a 50hz -6db (in my opinion) test tone for the subs.

Thanks guys, hopefully attempt #2 will have better results.
