I have been looking on woofersetc for a couple of days now and just can't make up my mind on this. What I am planning on doing is putting some tweeters / midbrange speakers in the back of my suv. I want it to keep up with my BTL 18 when I have the back hatch open. Overall I want to spend around a thousand on everything. Everything that's needed is back there as far as power and space. I was really liking the image dynamic horns, but can't find a lot of technical info about them. I am thinking 4 - 6 midbass drivers and 4 tweeters. I am willing to go active and was thinking about trying hifnoics because i've never tried them out before and they have some good prices. Help is appreciated, thanks.
