I'm looking to upgrade my car's in-dash receiver and all four speakers. What I have now is a really crappy system - pure stock from 1986. All I want is something that goes a bit louder and provides a bit more bass. I'm not looking for anything amazing. I know in HT there are brands that people avoid at all costs. What brands should I absolutely avoid and what brands should I look for?? I'm looking to buy used and spend no more than $200 for everything. I know that's not much, but I'm not looking for anything special. I obviously do not want a separate amp. I would prefer a CD player. Anyone have suggestions or anything they care to sell??
