Every1 is always talking about car audio, but I already have my audio on point.

I need some advice from some1 who has already been there and knows better than me.

I think xo vision is a good brand for your multimedia needs, but lately I have had my eye on Disel Audio.

I'm looking for a 20" flip down and 2-7" or 2-5" headrest monitors.

Which one has better quality and will last more than 6 months, like they have done in the past to me. (Does bass have an effect on the life of your multimedia?)

What brand will give me better resolution and durability? Xo Vision or Disel Audio.
(If not 1 of these I want to spend $400-600 on the flipdown and $200-350 on the headrest monitors.)
