I'm starting to get tired with the Stock Car Stereo on my red Celica(7G). I've been shopping around the last 2 weeks now and still unable to make a decision. I'm just not really good when it comes to Car Audio....but really craving for a better setup. Went to Brother's a couple of times and few other audio shops(Klasse, KK Lau, Jaya Audio etc) but still not able to make the decision...my budget is around 3-4k...any advise?
