Sure does, I don't have a targa top but I have a big moon roof. I don't like to use the a/c when it's nice out so I have all my windows down and that moon roof open, it maxes out at fifty, the volume knob, I usually have it on 25 or 30 and I can hear them just fine, bass as well. I have four 6x9 kickers. Two in the front doors and two in the back and a 12" sub in the trunk. No issues with hearing it
