JL C1-650 - not that great?

I have a pair of JL Audio C1-650s in my car and have never been a big fan of them. They are powered by a Kicker Key 200.4

I recently sealed and deadended the doors, then decided to power my rear speakers off my HU and use the Key to biamp the C1-650s. WOW, it sounds MUCH better! But I still feel like the mid-bass/mids just arent quite there. Maybe it has to do with setting the gain on the key? I was able to max the gain knob for the tweeters when playing a test tone with no clipping. The woofers started clipping around 3/4 on the gain.

I'm looking to spend $300 on replacing these with something else, what is the go to in late 2024 for a 6.5 component around that price range? I was eyeing the C2-650s but wasn't sure if I should stick with JL.
