So I bought a audio system for my car (2) 12" subs with the whole hook up kit an was wondering if Best Buy was a store that would install it for me?

Brother - Best Buy does do auto audio installations, but I'm not 100% sure if they do them at that location - don't see why not I guess

big papa or some after market dealer will not so sure best buy will guarantee the item they install

Yup

Yes.

Yes they should

Thank you guys 🙏🏽but I didn't buy my system from their store,will they still install it
