voltage of amps?

it is A/C voltage correct. what would a typical 100 watt amp put out as far as voltage? i am trying to figure how to balance the power of two of the same amps.

Yes, it is AC voltage. More info is needed. To measure and set it correctly, you will need a proper test tone along with your meter. JL has a chart out that may or may not help you depending on the amp. There are online tutorials with a formula. I think it is: sq rt (watts x ohms) or something like that. Don't quote me though! Google "setting amp gains" and you should find what you are looking for.

what do you mean by balance? as in the exact same gain level? you need to make sure they are both taking the same load. if one is @ 2ohms x 1 and the other is at 4ohms x 1 then the gain levels will be different as well as the desired voltage. if they are the same all around, just get the little arrow as close to the same as the other one

You are confusing me..... I'm no an audiophile, but I did stay at a Holiday Inn Express.
the formula is.....P/I=E to figure the voltage correctly, you need Power(100 watts)/ I current(how many amps) to equal E (voltage)
Find the resistance of the speaker load, say 3 4ohm speakers in series are gonna be 12 ohms..... you can take the resistance and divide the power by resistance to figure your voltage also..... i.e. 100w/12ohms will give you roughly 8.3 volts.... If the speakers are in parallel??? I'm way to drunk to remember the formula for that.

yall are making this too difficilt.

two identical amps, lower quality hence having two of them.

two speakers, same size, brand, VC configuation.

so, i play test tone, check voltage of amp A, then repeat with amp B. correct, and adjust gain till they are equal. i have a high/hold setting on my meter, mainly just curious of the voltage setting i would start at. 20-40-60-80-100-?

ok, the JL site in that link did help

Sneaky, do more than just match the amps. Make sure and set the gains correctly to avoid clipping.

lol... what you just did only matched the two amps gains to be exacttly the same... which i dont know why you would want that... lol, inspecially being that neither one were properly set to begin with...

and i dont think you understand that we CAN NOT TELL YOU WHAT VOLTAGE TO USE!!!! WE NEED MORE INFO!!! you need the impenance to take into factor or else you CAN NOT figure out what voltage to use.

it would be 20volts @ 4 ohms
14.14 @ 2 ohms

OR!!!! when ever you first hear clipping if it is a lower end amp... which ever comes first
