Re: High Pass Crossover Clarity Effects
Raising the HPF on your mids may increase the clarity if they can't play 80 Hz and higher notes clearly at the same time. Since this varies so much we can't tell you if it sounds better with a higher HPF frequency. Set your subwoofer LPF with the enclosure located where it will be permanently.
You could be hearing the effects of poor cabin acoustics, a poorly performing speaker up front, or other issues such as an equalizer that should be adjusted to compensate.
