first off shu t the f uck up john, no one cares what you think and you really dont answer people questions, u just ramble on about non sense
now to answer your question i cant speak for every insurance company out there but i had state farm and when my system was stolen they replaced everything. I never told them what i had in there before it was stolen but my plan covered making the car to how it was before. So i would just make sure whatever insurance company you go with that it includes whatever is inside the car. it woud be the same thing if you had a laptop or other expensive things in the car, they would be covered as well. just make sure you keep receipts and serial numbers of everything you have. I think that would be the better way to go about it then to tell them upfront you have thousands of dollars worth of audio equipment and then they will charge you an arm and a leg on your monthly payments. judt try and find a company that doesn't have the 5k cap, or ask progressive if you can up that to 10k or something. riasing it to 10k shouldnt raise your premiums too much. another option would to use renter insurance if you rent or homeowners insurance to protect your system against theft. I know that wont help you when you car isnt at home but it will be alot cheaper. as for what insurance company is the best you will just have to use the internet and get some quotes. i dont think one is that much greater then the others. the place i use now checks like 100 different companies and finds me the best deal. i dont know the name of those type of companies but ive always found those companies gives you the best rates. hope that helps.
