Hey guys,

I have a 2003 E53, non-navigation, non DSP.

I went to the crutchfield site (which is great btw) and looked up speakers for my e53.

If I want to upgrade the sound of my car, can I just buy the speakers they sell, will that be a good enough upgrade to the car?

I pretty much want the easiest sound upgrade possible without sacrificing space in the car. Would I need to buy an amp and/or sub also?

Thanks!
