Testing Pre- amp outputs?!?!?!?!???

[Mrwho2]

i was wondering how i could go about testing the pre amp outputs on the back of the head unit to see if they are putting out a signal?

You'll need a CD with a sinewave and a VOM that can read AC voltage.

A VOM that reads ac voltage is no problem, but im not sure about the cd with sinewave, what exaclty is that, and where can i get it.? And then how do i do the test?

thank you very much for the sinewave files. Now what do i do...? my guess is that i play the sinewave through my head unit then use my VOM on AC voltage to see if there is any voltage? shoudl there be a spec specifically for my face or is there a general a/c voltage for all outputs?

Should do somewhere between 0.1-2 volts.

Do you have an amp? Are you trying to rule out a possibility for no sound?

I will be doing this test tomm. on my lunch break. i have 2 amps, a 2 channel 400w pyramid and a 4 channel 400w Boss. The boss is brand new. Both amps get the power lights on but niether put out to the subs. I am trying to see if my HU that is like 1 month old has output
