I find the standard phase 3 front speakers/tweeters pretty decent. Tried a vibe component set which i thought sounded worse than standard.
Phase 1 rear shelf sounds way better than a stealth shelf. It has tweeters which makes it sound a bit clearer rather than muffled rubbish. I bought one for 99p on ebay lol
Edit: i may have to change my previous advice and say try headunit with a sub first, it's always been enough for me and i keep it on the most minimum setting so it's just enough to add a balanced amount of bass. But each to their own
