thanxs a lot for the compliments....well yeah im not too sure what a pac bypass is, but since the audio place had a tough time installing my Alpine D900, they didnt want to mess with it, so they installed this bypass that allowed me to get the same sound effect as if i had a good stereo, without having a stock sound. I think it is a Pac bypass though.
