My father hasn't had a proper stereo in his car for a good 10 years. Well I got him a couple pair of Pioneers premier speakers and a 5 channel amp. I plan to ad a very small box with a 10". But he insists on keeping his current cd player. It only has 1 rca ouput and the amp wants 3 inputs. F R and Sub. So was wondering if I split this rca output a few times, is that bad news? Or should I just go ahead and buy him and HU and just put it in there when hes not around //content.invisioncic.com/y282845/emoticons/up2something.gif.dd110ecf3ae4b76050d87598f2f8de7c.gif. I got a couple weeks to come up with a plan. Thanks
