No, I wouldn't say you went wrong buying all coaxials. Them being coaxials won't have anything to do with there low-frequency response. If your amps or head-unit have/has built in cross-overs, see if they are set to hi-pass. If they are, thats why there is no bass. That's all I can think of.

Put a couple of 15in. Mmats subs in her. Theat will deff. fix your problem.

i think im just gonna put 1 jl w6 12" in there or 2 kicker solobarics i could bout my buddys 12"mmats but he sold them already
