Another option aside from horns, would be an a-pillar install. With your mid and tweet close to on axis, it will increase the feeling of spl compared to similar components in the door or dash. You don't have as much reflection off the windshield to try and tame, like dash mount.
Horns are nice, but can be a mother to tune and they have their own sound. I'd love to try them some day but there is a fair amount of fabrication and tuning to get them solid. Not that there wouldn't be with an a pillar install. Lol
Guess it boils down to what your comfortable with. I had my mids in the kicks, and they image beautifully, but my body and center console eats up a lot of output.
This time around it'll be a-pillar With nothing between me and the sound.
