I usually download test tone from realmofexcursion.comwho said to use a 1000hz test tone for sub amps? lol
you can pretty much use any tone that is in the freq band of the amp that isnt affected by any filters (assuming you didnt turn them off).
i usually use 50hz -6db test tones for subs and 1000hz -3db for component amps. never had a problem yet and i think im getting the most i can out of my amps without an oscope.
you want the blue and white wire. and the -3db test tone will be fine. i just prefer -6db to try to just squeeze out a little bit more power.I usually download test tone from realmofexcursion.com
so there is no -6 Db, so for instance I got 50 Hz -3Db, will that be ok?
