Sound System Insurance

My insurance company doesn't offer any stereo equipment or rider insurance, and my dad is paying of it. He said if I could get a quote that was the same or better where I could pay for the extra insurance, he would switch. Of course I couldn't. My question, are there separate companies that would insure just my sound system?

The way around that is to have those items endorsed on to your homeowner's or renter's policy.
