What frequency would I tune a box so that the bass could be felt outside of the car? This is NOT so that I could shake other cars at traffic lights or or ride around disturbing but it is for a one on one competition between me and a friend. I know it sounds crazy but we will compete and see who's bass can be felt more outside the car. I'm going to use either 1 15'' L7 or 2 12'' L7's of course ported.
