Iv just got a decent Alpine HU with sub and amp.
1.Its impossible for them to know I have sub and amp unless the follow me home from hearing me
2.Mine isnt SILLY expensive.
0% chance Im even giving my insurance the chance to charge me more than they already have the cheak to charge me.
Technically if your car gets nicked and they find it with these in, surely they could say the car was, in theory, made more 'desirable' as it's got a flashy cd player and sub?
You should be covered for £x00 worth of audio anyway on your policy, so i wouldnt worry
