yes is true....currently I, ve a set in kick panel, the suound is pretty....if you made this correct (the exact litters, speakers direction, etc..) you,ll have a amazing sound....
all the audio system in my car has DLS speakers and amps, and really the sound is amazing......i heard the nobellium was amazing, except the price are experience......i don,t know what is your budget ¡
i have the same ...but the tune in mine is:
hp = 50 htz
lp = 80 htz
you said, "turn off the loudness for more cleaner sound"
in my case, this is turn on....
what do you do recomend me ?
Some volvo use factory dynaudio speakers, i don,t know about your car, but in my opinion use the factory amp and the speakers and only install another amp for a sub ....i recomend a good sub, like a DLS ..
