I currently have a Mercedes A-Class X Reg (2000), When I first received the car there was no stereo in there just the factory speakers, I bought myself a new head unit - DEH-5200SD CD Tuner with iPod Control, Front USB, SD and 3 Hi-Volt RCA Pre-outs (2010 Model) - Pioneer Car Audio - CD Player

And I noticed straight away that only 2 of my 4 speakers were working (The Passenger Front Speaker & Driver Side Rear Speaker). I thought maybe the speakers had blown so for my birthday just gone I got 4 brand new speakers & first off I tried to install the Driver side front speaker to see if changing the speaker would fix the problem BUT IT DIDNT!!

I find it quite strange that the speakers not working are on different sides & one is front one is rear.....

I checked the back of head unit and everything is fine...

Can Someone PLEASE HELP ME!!!???

Thanks
