my pioneer nav system has only 2v pre-outs, and i really don't want to replace the headunit (i like it). the loudness on my stereo has gone down the drain though when it went from 4v factory to the pioneer's 2v's.
i have heard that i could install a line driver such as this and it would compensate for that:
OverDrive PLUS Line Driver with Input for Remote Level Control
does anyone have something like this installed? or can anyone tell me how this works, and how it's installed?
i don't want to buy subs, or change from the bose setup, or replace my headunit. whatever options that leaves me with to get my loudness back up, i'm all ears!
