I already have most of my set up.
I have a sub and amp in the trunk. As well as a 4 channel amp powering the stock door speakers and 4 inch speakers in the dash. And an Audison bit10 processor installed also.

I would like to replace my stock system.
I am torn between getting some quality components or just getting better coaxial door speakers and upgrading the 4" speakers in the dash and running them with my amp and processor.

I'm no car audio expert so would someone be able to tell me which would be the better route?

I figure my second option should be much cheaper than getting components.

Would the components make a big difference?
