Is This Right

[connersdad19 10+ year member]

I have the AP-2002 to power my door speakers...i am going to set the gains, etc. with a dmm please tell me if this is right...

My Speakers are 4 ohm impedance i currently have them wired at a 2 ohm load into each channel...its a 2 channel by the way...my speakers are around 50rms a piece so here is what i have

My Amp Does 125x2 @4ohm

as my speakers are about 50 rms i did 100 x 2 @ 2 ohms and came up with 200 and the square root of 200 is 14....so do i need to have my dmm say 14v? please let me know if i am right or not..this is my first time doing a small amp like this.

and is it better to use a 1khz tone or use pink noise..? and do i just hook the dmm up to one channel?

Square root of 200 is 14, so your DMM needs to read 14v AC. 1KHz tone is what I use.
