^^^ my suv had a bose system when i got it and i did the LOC to add subs worked pretty good.

 

shared_pm me if interested, i can set you up and take car of the complete install for you.

 

cool..i got a nice LOC now and my wiring and what not. should i tap the loc into the wires going to the stock sub speaker for my signal? these wires would be after the stock amp leading to the stock sub. im only hooking up 1 12" sub so i dont need to worry about it being in stereo. the loc has like 3 or 4 sets of wires that are left/right and what not right? does it matter what set of wires i use from the speaker to the loc??? thanks for all the help guys
