Here is the Federal BP-100 speaker. This is the model of speaker they use in the Crown Vic police cruisers.
This is the perfect speaker to use for the Bronco, if you want to put in a powerful PA. This speaker weighs about 15 lbs, so it is not a trivial item. Some cutting is necessary to get this baby in, but fits perfectly. Any other speaker would require more cutting and mods to get it in the grill where it needs to be. If you do not grill mount a speaker this powerful, you will be sorry.
