yeah i have allstate too, and i have ZA coverage, which basically is meant towards audio, rims, accessories basically. i had to learn the hard way. i have 2 cars, and my accord, they broke in and stole my kicker kx700.5, called the insurance (had full coverage for both cars), and when i took it to the shop. allstate guy said that i dont have ZA coverage, so they cant cover nothing. only thing they said is if they took the radio, then that would be covered since its part of the car, not outside or laying in the trunk if that makes sense.
so then i got ZA coverage for both cars, yeah i got ****ed because my agent never decided to mention this to me, so i am out of a nice amp. so yeah ZA coverage will cover up to $2500, and the deductible is only $100.
