Is there any way the strength of the radio signal antenna can be increased or is there anything that can be installed to strengthen it ... btw strength as in increasing reception strength for audio channels.

My house runs an powered amplifier for the TV signal cable... but no, haven't heard of the same type of thing for the car.

Might have to try a new headunit, some brands of radio are better than others.

You can get aerial antenna amplifiers from most electrical shops. :)
