Here is my question
I have a set of BA Pro 60's rated at 125 wrms @ 3 ohms
I have a Alpine PDX.4-150 which will be bridge 300 wrms @ 4 ohms (Stable @ 3 oms)
What should my voltage target be on my DMM
(125 rms speakers x 3 ohms) sqr = 19.37
(300 rms amp x 3 ohms) sqr = 30
(125 rms speaker x 4 ohms) sqr = 22.36
(300 rms amp x 4 ohms) sqr = 34.64
Also, Alpine amps are usually underated. Mine did not come with a birthsheet for some strange reason. Should I just use the rms rating listed or should I bump it up a bit as the amp is most likely underated?
thank for your help
