Wow, what service. I came in with and audio problem on my 5series BMW. The staff at S J Concepts are really friendly and helpful, going beyond what's required. I highly recommend this place, great service, great people. I will always use SJC moving forward. Best place in South Wales.

Found this place by chance as I wanted to replace the stock stereo in my 12 plate car for a unit with android auto and have it done professionally rather than do it myself as in previous cars I've owned. I couldn't be happier. From start to finish they were superb and very informative. They were able to answer any questions I had and gave me a run through of the basic operation of the unit after it was installed. I would highly recommend them for any sound system upgrades.
