Alright guys so I'm looking to replace the current stereo that is in my 2000 Roush Stage 1 but like all 2000's it has a two din set up. I'm not much of an electrical kind of guy so I don't know much on this topic. When I buy a new head unit what should I look for? Also when I replace the stock one do I need to replace both upper and lower dins or only the top? I plan on hooking up an amp and two 10" subs as well if that makes a difference as far as the head unit goes. Also do I need any specific mounting equipment to do this job? Any help is appreciated!! Thanks in advance!
