Is it possible to get line level output from a stock 01+ Mach 460 head unit? I'm assuming it uses line level signals through the harness that plugs into the back. I've tried looking around online, but I can't find any kind of adapter or kit to let me get line level outputs from the stock headunit (other than line level convertors, which I'd rather not use).

 

Only ever seen one adapter but its more or less just a line level convertor. If you don't wanna use one, then what did you have in mind? If you just lookin to add subs..Ive seen in a couple places, plug and play Mach 1000 components to add to the 460.
