I have a 2004 330 e46 coupe.My car is not fitted with a HK kit, however I have just purchased a HK kit for the car.
I was thinking of upgrading the door speakers and rear parcel shelf speakers, I was thinking of Infinity or JBl, I don't want anything flash just standard replacement sizes as I want the car to look factory.
I beleive I will require adaptor plates and plugs to house aftermarket speakers?
Is there any need to replace the 4 very small speakers part of the HK kit? Would also need to know the speaker sizes if possible.
Can anyone help please?
