We are still trying to get an answer to this question.
Zotac board with built in sound card. Just removed previous system (Clarion DZ775USB) that ran a Memphis 250x4 and a Memphis 1200x1 into 2 boston accoustiic G55 and the highs are Memphis Matched components (not coax). On previous setup, Clarion put out 5 volt signal and amps were set to 35-50% gain, with subs on about 40%.
Hook up carputer, Run jacks to RCA's to Amps. Turn it on, and music is ungodly loud. Turn everything off (by unplugging audio jacks) and go turn the amps down to NO GAIN. turned the bass boost down to 0%. Plug the audio ports back in and get "Pretty frickin loud"... this is when i realized that centrafuse was running at 15% volume. As I turned it up past 40% it was unbearably loud. Exited, went into winamp. Winamp was set at 5%. turned it up and it got ungodly loud again. Opened up windows volume control. I have either the wav out or the master volume control set to 1%, I have the amps turned down to 1%, and I still cannot turn the volume up over 50%.
The only thing I can think of is that the audio ports are trying to put out real wattage instead of 4-5volts. Although for this to be THAT loud, it would have to be some serious voltage.
Is this a common issue? do we need to change a setting somewhere so that the ports are putting out "Line-out" volume?
