Heah Sorry HE, I would be comparing 12' each, and only one sub, the rockford I would give either the rf 1050, or the rf 1001bd, the planet audio, I ould be giving a PA 850. I would give up some sound for loud, but not too much. My trunk is the limit, they can have as much as they want of it. I have a 95 neon. Any Ideas on this would be great, thanks
