you mentioned that if something happened to ur woofer then heaert attack
in order to savr from this, get it also insured
u hav to call insurance company & tell & add these extra stuffs with little premium( e.g if ur woofer cost 50,000 then get it insured by paying 5% of cost & be light mind)
even i suggest u to add central locking in insurance too
btw who is ur insurance company
