Why would anyone spend a lot of money of a hifi car audio system? You're in a small box with many potentially vibrating parts, when driving there is wheel and engine noise, non-insulated glass, airco noise, etc. So the only time music will sound right is when you're standing still, in a quiet park or your garage, with the engine off, and no wind. Ridiculous waste of money. Better off buying a high quality player and a good noise-cancelling pair of IEMs. Much cheaper, no installation required, better sound quality, and you can use them everywhere else too.
