I have 2004 Hyundai Sante Fe that had the monsoon stereo and amp in it. I replaced the stereo system with a much upgraded up to date but inexpensive pioneer double din. I did not replace amp so that’s still factory as well as speakers. I want to replace speakers, at least front n rear side speakers not necessarily the front tweeters. And was also thinking of a small subwoofer. Don’t wanna pay a fortune I can put it in myself. Nothing blasting loud I’m not a teenager anymore but ya know!! I need some setup suggestions.
