heres what i did.
i basically tapped wires from the rear speakers and connected to the line level converter . and then went to the amp
the other day i opened the trunk to see that the wires had been disconnected from the line level. ( the wires tha were soldered inside the actual converter unit )NOT My JOINTS.
My question is it possible to tap the wires behind the head unit to avoid all the wires and the hassles.

OR IS there another way to hook up a sub to the stock deck
not using the linelevel
thnx.
JOe.
