Thinking of Installing New Head Unit...
Hey there! I was thinking about installing a new head unit in my 2010 Chevy Cobalt Sedan (Without Onstar).
My concerns are this:
1) I have JL speakers in both my front and rear and they sound AMAZING. How much more sound improvement will I get it if I install a new head unit (Specifically looking at a Sony)?
2) Will I need the expensive Wiring harness? I've heard yes and no. If I dont use the expensive wiring harness then what specific things will I lose?
Thanks in advance!
