Recently bought my FJ and the stock sound system is terrible! I wasn't impressed, I was expecting more power from the monster's in the doors!:smile I went to CrutchField and put all my info in, the only thing I'm unsure of is the speaker sizes. I have the 6 speaker system, 2 in dash, two in doors (driver's side , Passenger side) and two by rear hatch. I was reading some of these posts, and I'm still unsure of what to buy! Any good recommendations on speakers? Within the next couple day's I'm ordering a Sony XAV-W651BT to replace the Kenwood non bluetooth unit the car came with.
