I have recently bought a Peugeot 405 estate and have fitted a Kenwood CD player in it wired to the original speakers. In the rear of the car are a pair of Pioneer speakers which are not connected to anything. A friend gave me an old Blaupunkt BEB 40 graphic equalizer/booster which has 2 speaker plugs on the input leads. Can i use the RCA line out on my Kenwood CD to feed the graphic equalizer to run the Pioneers? Also the graphic equalizer says 2X20w on it but there are 4 speaker outputs on the back and a fader control on the front, so how can it be 2X20w? Any advice much appreciated.
