Will my new stereo and sound equipment invalidate my car insurance?
Installing a new stereo and sound system alone won’t invalidate your car insurance – but not telling your insurance provider about it could.
The most sensible thing is to talk to your insurance provider before investing in an audio system. They’ll be able to tell you how much it will affect your premium by. It may be as much as 10-15%.
In some circumstances, an insurance provider won’t cover the extra equipment. In that case, you may want to re-consider your purchase, or shop around to find someone else who will provide the cover you need.
