To cut a long story short, I have Discovery Media plus in my 2021 T6.1, full camper conversion and had a Focal Ibus 2.1 active sub and Hertz Cento CK 165 front speakers and tweeters fitted at the time of conversion nearly 3 years ago, I’m not convinced the sub or crossovers are set up correctly and I’m also thinking about a new head unit due to ongoing issues with VW unit, can anyone recommend a good ICE installer / supplier in Somerset please, needs to be local, thanks
