ok, i have the Bose accoustic sound system in my car. theres a small plug at the left corner of my trunk (if your standing at the back of the car) it connects to the Bose unit, and no its not the bose plug. This plug it a smaller, squarish plug and its quite long. could you use this for an amp or somthing? i was wanting to put in 2 subs but i wasnt sure what this was for.

 

I doubt it i don't think there are any outputs in the system for amps.

 

oh, thats kinda what i though. so does anyone know what that plugs for?
