It might pay off to look into who's supplying them of car audio stuff since its mostly just the headphones that suck, haven't heard anything concerning about Beats car audio.Yup, Beats are actually not that great and audiophiles are not a fan of the headphone with cheaper and better options out there. I'd stay away from Beats and go for some other aftermarket brand.
I think that can go for a lot of other brands, like a lot of thing it probably comes down to the specs you're working with and not so much the brand. So even Pioneer could be worth getting, and even cheaper. Doubt many people here want to spend top dollar.I'm not one for audio upgrades, though I have heard that Bose car audio systems are generally produces pretty good sound without requiring 1,000-watt outputs.
