I have upgraded the head unit, two door speakers and tweaters but found on a recent trip up to Glasgow that it is still hard to hear the stereo with the top down.
I have read that the optional sub-woofers that can be fitted behind the seats makes all the difference. I am thinking of doing some interior work and would like to add these speakers first. Has anyone been able to obtain the box from Fiat or elsewhere? I have also seen on ebay a replacement console box with speakers attached. Has anyone installed one of these? Cheers.
