I have a kenwood cd player which has no imput and wanted to possible add a playstation or game console and flat screen. But no inputs on my stereo, Do i have to get a new head unit, Is there equilizers with more then one inputs, or is there a way to add input another way? All help or suggestions i would appriate

I know the audio control four.1 has an aux input, cuz I have one

Like Paul said most have a AUX an dif your does not yes you will have to swap you r h.u or you can get a SWITCH which like its titles does just that. you should be able to buy them at electronics shops .

i know that at bestbuy they sell a little thing that you can hook an aux or rca's up to and it sends out a radio signal and you change it to that station on your head unit and it works that way.. maybe somethin to check out

those little RF boxes SUCK
