I have 2 infinity 12" subs and a 900w (peak) amp, they are in a 1991 mustang gt and work great, but they dont have much high pitched bass. It pushes the low tones really good but the high ones just get quiet. Ive looked at settings on the amp and everything but Im just not sure what it could be. I was thinking about maybe getting a single 10" that would maybe hit the high pitches better but idk. Any suggestions or opinions? Sorry about the sideways first pic
