yup,, big difference between .707 & .637 ,, & Peak to peak
Funny, now when i power up my R300 gets hot. ,, its a tiny one under my tuner.
the white paint marke went brown and some tad bits of smoke got loose.
this is directly off my red wire T2 ! LOL. adding that to my list .
so i just measured the voltage on each side of the 500 ohm resistor. I was skeptical my original resistor would hold up casue i felt like there was a reason why it was big in the first place but considered it to be a bandaid to poor existing ckts and it compensating.
so i got 236vdc on one side of the resistor R102 (call out is 300 ohms for a pm speaker) but i have a 500ohm installed temp. i have 236vdc on one side and 306vdc on the other after i hear the speaker cthatoming on line.
thats about 70VDC ,, 70^/500= bout 10watts.. or about 15 true "ish".
if we use 236vdc , thats 111watts,, or 150w true "ish".
so why am i installing a 50watt soon?
i want this to say cool enough so that when i touch it , it is warm,, not boiling hot
to be honest i almost bought a 120watt chassis mount today but decided to go with what i was told.
something tells me this is a very dirty dc signal and has characteristics that lead me to think i should treat it as a AC circuit for math and component sizing reasons.
