intense gain frustration

[pablo4429 10+ year member]

OK i have read the sticky and done it to the letter and herse what happened

-i have a profile CA640 which is 75 rms x4 @4 ohms

-4x6(2) infintiy refs 45 watts rms

-6x9(2) kenwood 6979 ie rated at 65 rms

now i only have one set of preouts from the deck so i used 2 y splits and wired them according to profiles manual. when i went to set gains i can only get my front right channel to get the right voltage ( channel 4) @ 13.4 volts. the 6x9 on that same side needs like 16.5 or somethign( idont have my calc) but the absolute lowest the gain will go is 21.6????? also the other two channels are giving me negaitve reading unless i put the + on the meter to the neg on the amp and vice versa then i get a diff #. do you guys think it could be my tets tone cuz i made it on NCH but i added 10 or 12 decible (i forget) to it bescause i heard they started off at - 10 or 12. and im using a 1khz tone

You need to have a 0db test tone. Try to find another one or make a new one.

check out this site and see if these would be good test tones but read the bottom

No those were designed for CPU audio cards.

None of them will be suitable for setting the gain on your amp. I actually have a test tone cd layin around. I think I need to locate that f-er.

well i just tried it with the new test tones and the front i think r working because one side has the right voltage and the other has the exact same number but just negative i think the back gain nob might be ****ed cuz it doesnt go any lower than 21.6 ans it stays there for like 0 to quarter way on the dial
