Q: So my car(2015 challenger sxt plus) has 6 speakers, can I replace them with 6 of these ?

No, these reproduce low frequency only.

Q: Do these speakers have a cover?

Mine arrived with no protective cover/grills. I’d say no. It did not deter me though. I found suitable covers easily at a local “shop”. No problem compared to the value and performance I’ve experienced with this sub. I’d recommend no doubt, especially if in a pinch for space in vehicle. Get these! Lol. No covers though when I purchased mine. Good luck. Jam on! Peace

Q: Has anyone installed this into a tahoe, suburban or yukon?? if so, do you have photos of how flush it sits??

Not a Tahoe, but it sticks out about 5/8 in from box face.
