Thank you for your response rgwm,ive booked it in my nearest alfa garage which is inter services,they are very good guys down there so hopefully they can hook it up an do a diag.Im assuming a new battery will be around 80-100? also the sound system in the car is wack! i do how ever have a sub an amp, can i connect it up to the factory fitted system or is it best to buy one? and which one if so? and what gauge wiring will i need?....i did have the sub and amp in my alfa 146 had it wired up to a ripspeed dvd player,but no longer have the dvd headunit,and i never fitted it either i had someone do it for me as i dont have a clue where to start lol any help would be great,thanks again.
