Hello everyone. I was thinking about this for a long time b 4 I did this and I did ALOT OF SEARCHING first. What I got was alot of different stories. So I just went for it. If you have a bose and want to keep your oe speakers ALL YOU NEED TO DO IS TAP INTO YOUR AMP. It was not that hard at all. I would run rca's from the head unit to the trunk just in case you want a amp later. Just get your acc power from the cig lighter. You can even use the power and ground from the bose amp to run your new one. I will be adding a 5 ch amp to push a small 8 or 10 inch sub and oe speakers for now. I will be selling all oe head unit amp and changer if any one want it i will let it got for kia prices. lol will post better pics soon.
