if i use the wires from the rear speakers it means i then have to run the wires all the way back through the car to get back to the parcel shelf i wondered if i could tap into the wires near the doors. i may have to wait till i buy an amp anyone know a good place to buy one cheap im not really after puonding base just want a bit more volume. im still using the volvo head unit as it seems very good with the sound quality, i do have an old pioneer mini disc head unit and six disc changer but i cant be bothered with using it, although when it was new it was a top of the range best you could buy model.
