Comments:
I listen to rap 90% of the time. I know nothing about installing audio so I had my local shop do it for me.
I've been waiting for a full build since I was 15, now in my 30s.
It has more volume and loudness than I'll ever need, good problem to have.
At certain volumes and frequencies I still hear chatter but I'm into diminishing returns now. Rearview mirror itself, headliner, dome light housing. Trunk floor etc.
Rear speakers are just for fill. Required some DSP tuning as well. I noticed vocals sounded clearer leaning forward; now they now longer feel "trapped".
They mounted amp and dsp underneath the 2 front seats, which I thought was clean as hell.
Still don't understand the bass knob. I assume it controls voltage to the subs? Volume increases rapidly but then it caps at about halfway.
I'm happy though, worth it.
