are test tones quiet?

[sounds_explicit]

should you hear any bass while setting your amp gains while using test tones?

and where is a good place to get a test tone at. thanks

when you use test tones to et your gains remove all wires from terminals so nothing creates a noise.

Xplicit udio app has a tone generator. If you're sub is hooked up, yes you should hear a sine wave.

so disconnect my wires for the subs at the amp? so the amps terminals will be empty?

and if so how does that actually work then? if there is nothing pulling current from the amp?

Unhook them (or the +) to set gains using a dmm. If you're doing it by ear leave the subs hooked up.

nothing needs to pull current the amp puts out AC voltage and thats what you read with the dmm

okay. and what exactly am i looking for? 12 volt setting top drop under 12 volts? or is there a certain ac voltage i should be looking for

depending power desired and ohm load everything is differnt.

doesnload ohms law app on your phone, its free and the picture is black with a white triangle with V.I.R. in it

ok so if i did it right. i take my rms or wattage desired and find the square root of that and that is what i should be looking at ac voltage wise ? so 1500 watts at 1 ohm is about 38.70 volts so i should set the gain to reach that voltage with all my head unit settings to lowest? sub level, sla, loudness, bass, set it to the voltage and then i can adjust the settings on my head unit?

yes 38.7v and yes have evrything flat or off. also you sure your amp does 1500 clean? what amp?

im guess it does 1500 watts clean. its a crappy hifi amp 3000 d but i know its not putting out 3000 watts.

if there is a way to measure my wattage being produced i would love to know.

got a fund going for a better amp to push around 2000 rms

An RMS volt meter set to AC volts will give you a reading from the amplifier outputs. With some basic math you can calculate Volt Amps, or VA, but that alone is not enough to give you power, or watts. You also have to make assumptions about the current supply into the amplifier. It's not very accurate.

Okay well until I get a amp that does rated then I'm just going to bump it down a little bit and go from there.
