used dmm to test amp@ 2 ohm ac volts at l715 was 89 volts added my two l512 subs brought it to 1 ohm and measured 73 vac what does this tell me ? 12.8 volts as car was off 150.2 tl i baught the amp used at a db drag meet and the guy said it was a -ss wooper of an amp. seems good never has missed a beat. knock on wood lol

 

I am not sure what you are asking... VAC means nothing without knowing what current is being drawn.

 

i measured at the woofer ac volts and @ 2ohm it was 89 volts and when i dropped the amp to 1 ohm by adding 2 more woofers i had 73 volts i used a test tone and made sure it didnt clip probably had a bit more to go maybe 2 to 3 clicks on the head unit before any noticable distortion

 

uhhhhhhhh huh ........ and we are to expailn what now ?

 

Guess i want know is this right way to measure peak or rms????? and it is supposes to be 2000 watts at 12 volts. Like i said it has 89volts @ 2 ohm and 2000 watts is 63.3 @ 2ohms thanks

 

To know actual output, you need to find the current as you cannot measure the impedance rise.

 

in simple terms, you are getting less power out, those amps do not like to be loaded down...its "hold back" to protect itself...
