I'm using some 6.5 infinity components. Had to trim the housing some to modify them to fit, but not bad. They sound great compared to what was there. That being said, I got them for $10 at the junkyard (someone messed up not seeing those there). I never buy audio equipment new personally. I always use facebook marketplace or craigslist. Someone is always going broke and needing money or just upgrading because they want something better. That's just my 2 cents though.
