Thanks for all the posts and info guys. To expand further (and not complicate the issue), I'm really not that fussed about bluetooth and usb. I will happily settle for a just an improvement in the quality of the audio. So what I'm asking is how easy is it to just upgrade the kit?
I have the headunit that the guy in this video ends up with, except it's definitely not producing anything I would describe as "professional" audio. See attached picture - that's the headunit I currently have.
I believe the current system in my car is the very basic system. 2 door speakers (no tweeters) and 2 rear speakers in the shelf behind the rear seats.
So, should I replace the headunit in order to improve the amp, and replace the speakers as well? I really like the OEM look and would love to keep it that way if possible.
I also have a large space with speakers cables lying around, on the passenger side, behind the trim in the boot. What's that all about?
Cheers in advance guys.
