whats a good audio speaker?, I don't know what to get. Options

[soulshadow]

Im looking for something to upgrade my sound system inside the car.
I don't want something too expensive yet too cheap just around 100 for a set of 2 for the front and the same for the rear speakers.

What sizes will fit and which one will give me a better thump than the stock ones?
I got a sub and amp already.

If you want a better "thump" from your new front speakers, you're going to need an external amp to power them. You'll probably lose some of that low end "thump" when you get rid of the stock speakers if you run them off your head unit, it's just how things work. And for a better sound, look into getting a component set (a midrange, tweeter, and external crossover,) and a high pass crossover.

The best way to decide what you want is to go out and listen to as many speakers as you can; they all sound different to everyone.

6.5" will fit both front and back, but mounting plates will probably needed.

Some good inexpendive brands are CDT, Infinity, Boston, JL... and there are MANY others. It's all pretty much personal preference. But remember - you get what you pay for.
