A mate of mine is hoping to put a set of 6 x 9's in his BA ute but we're wondering if the speaker wires for the back speakers would be run to the pillars or something, or weather they are just coiled up at the back of the head unit. Worse case we'll put an amp in but if we can he wants to keep the cost minimal.. So has any one with a BA ute added back speakers to the stocko head unit without an amp? Appreciate any help thanks guys
