Well good news, I went down to the local stereo shop and purchased a line driver for the sub preouts. It worked like a champ, It brought the lowly 2v up to 4.2 and my system was booming once more:)
Talking with the install guy he was telling me that wasn't the first time he's had to do that, as he discribed it, the AVIC series, in order to compete price wise put a smaller amp to save cost while keeping the video/multimedia side rich.
All I know is for 20 bucks, I got my boom back:D
Thanks everyone for your help and interest!:)
