I'm arguing with a 17 years old customer, telling me is "kicker" system in his car can reach 153 db w/o any prob (probably distorded like hell). I don't care at all for car audio, but is he lying?? He says that for around 2000$ it's easy to do!! The site kicker.com says some people are reaching around 170 db with 20 amps and 20 subs!! Is it only distorted sound, or is it actually listenable?? Are they all crazy and anxious to go deaf by 20?? When this young loser is around with his car, all the bottles in my pharmacy are shaking!! And I was thinking that reaching around 110 db at home was really loud!!
