amp powering question

[unknown00 10+ year member]

**** so voltage=sqrt(power*resistance) ?

that sucks a lot...if i put my gain just above half way and listen to my music at my normal volume it goes a little above 250watts...guess i have to keep gain half way //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif and with no bass boost this JL sub is hella weak

I would put closer to 350 on a w3....yes it is over their rating, but with clean power and a good enclosure, it can handle it

didnt you just spend $180 for them to install the amp? and they didnt even set the gains?

jw sometimes when i am measuring the voltage it jumps to like 200v...is that okay?

could just be the dmm...some of the cheaper ones will do that

never used a GE...I have an Actron

other than the meter itself, it could be the connection between the tips of the probes and where you are sticking them
