Hey all, i have the stock audiophile system(sub and amp) and there is a guy on here selling the system out of his 08 KR, and im looking at getting it. The paint on my HU is peeling off, and the speakers are blown.

Heres my question, Is the stock system good when its brand new? (ive never heard it) and is it worth it to get the entire system or just to build my own? hes only asking 250 which seems like a really good deal.

and if i wanted to upgrade to a better 8" sub, how hard would that be?
