Hi, i have just instaled the Pioneer SPH-DA230DB in my non bose 2011 a3 cab,i have just replaced the stock speakers and replaced with some Herts compononets .
My HU as RCA inputs for front and rear but at the moment i just have the fronts connected as thats all i have ..My next step is to fit rear speakers ,there are grills but no speakers in but it looks a straight tforward job to fit some in although they would have to be 5.25 inch ,what i would like to know is what is the best way to pick up the rear speaker wires from HU (harness)..which the colours are Green -green and black Left rear speaker and Purple -purple black right rear speaker ..Its been a while since i upgraded a HU so any help would be apreciated ..Thanks
