Coax Or Midrange Rear Door Speakers

I am looking to replace the rear speakers in my dual cab. I replaced the front speakers with a Memphis Audio SRX60C component set last year and added a Kicker Key 180.4 to power them and the rear door speakers. I also have a 10" sub behind the rear seat. For Christmas I am getting a Kenwood DDX9907XR head unit.

I am wanting to replace the rear door speakers, but I am not sure if I want to go with a coax speaker or just a midrange. Right now it feels like I am missing something in the sound stage. I know I miss a fair amount of drums, but it also feels like I am missing a little bit of the upper range as well. However, I think that might be because I am still using the stock head unit.

Budget is always an issue, especially after dropping the $$ on the Kenwood head unit.

Thoughts?

 

Put full range in the back. You aren’t fixing anything in front by sticking midrange speakers back there.

 

i got a thread up right now i just redid everything.. got rid of the 3 way front 6x9s and put some 6.5s in the front and some 8" mids in the rear door and upgraded the JL tweeter and it sounds killer! 2 12s behind the rear seat.. the vocals are stupid loud and crystal clear.. (there used to be JL 6x9 front and JL 6.5 rears.. swapped kicker 6x9s) the new setup beats it all day

 

Rear speakers without any processing aren't going to do anything for your stage. Those are for rear passengers. Go with coax.

Really wanna bring in the drums for not a lot of money (albeit a whole lot of work)? Seal the & deaden the front doors.

 

I have a Kicker Key 180.4 for the signal processing. I realize it may not be the best, but I think it does a decent job.
I picked up some Kicker 46CSC654 6.5" coax's yesterday. My 80mm Noico was delivered today and my fast rings should be here Saturday.

Hopefully once the new HU, speakers, and deadening is installed I will be happy.

 

The key will no doubt do its job, but it won't sum limited bandwidth rear channels to improve staging.
