What our customers say:

  • Everything top
  • Friendly and competent service
  • Installation on site
  • Extremely comprehensive and professional advice at any time

For me, a brilliant package of price and performance. If you like to drive your classic and do not want to miss good music and sound, as well as safety (hands-free phone), this is the best package for you. In the future, all my classics will get a Sonority Sound System. Even my modern leasing company car with upgraded HiFi from the plant can not keep up with it. Quality is when the customer gets more than he expected. This is definitely true for me. THANK YOU!
