Currently I have JL XR 5.25” coax in the rear of my C6 coupe and looking to upgrade. They’re good but getting long in the tooth and looking for replacements that are quality and handle more then the JL’s(60w RMS). I’ll be upgrading amp shortly to a hertz 4 channel 150w X4. Between 80-100w RMS is what I’m aiming for these coax. Would be nice if they drop into the openings but I’m willing to do a little modification to make it work. I’m all ears for those who know. Thanks
I ran Infinity Kappa 52.11i off an Alpine PDX-v9 (100W/ch) in my C6. One day I'll put them in my C7.
I just looked them up and they have a RMS of only 55w. You’re putting 100 to each? They do have a high sensitivity rating. I never heard them before. How do they sound, especially the tweeter? I need a really smooth tweet right behind my ears. The JL’s are perfect in that regard but looking for something that can handle more power.
Sorry. It's been over a year since I switched cars and just now remember how I has them connected. They were just running off the factory amp. The PDX was running my door and dash speakers. However, I do plan on running them off the PDX amp whenever I upgrade my C7. I do like the sound, not harsh or overly bright. My set will be tuned to be front stage with rear fill with either 2 x12" or 3 x 10" subs.
No co-ax's in the back. Run a regular driver. There are so many to choose from that are adequate. What's your budget?
I don’t want to go overboard with the rears as far as cutting up to mount components. I was recently looking at Morel tempo ultra Integra 502 coax. If those would fit with minimal work I think they’d suit just fine. $300 +- is is right in my window. What thoughts do you have in mind?
What are you trying to do with your setup? A $25 Dayton will sound great back there. Rear speakers are NOT "stage" speakers. In the C6 they're used to fill gaps in frequency range, and add to volume, because the C6 interior is a bass killing nightmare. I run Focal K2P 5.25s" back there as a fill from 200-2K Hz. But to be honest, they're not really "needed." I use them when I want to just get stupid loud.

In a nutshell, I want the capability to go louder while still maintaining sound quality.
I love the sound fidelity with my HSK Hertz components, JL XR rear fill and JL stealthbox 10w3v3 both powered with JL 450/4v2 and JL XD600/1 but time for more juice to the rear fill where the XR’s live, they lived a good life but time to go. I’m open to suggestions
Honestly man, the rear driver isn't going to contribute much. Almost any driver you put in there will get the job done. I advise completely against 2-ways though. They will confuse the sound stage.
The 5.25" Dayton neo is pretty sweet (and it's only $25 a speaker) and plays flat as Kansas. I found my Focal's on eBay for $300 and they get it done. Your amp is good for 75W RMS @ 4ohm, so poke around in the 60-80W power range and you should be fine.
$25 dollar Dayton’s, no thanks. I have pretty nice JL’s in there now getting almost 75w each and as I said I’m upgrading the amp to Hertz 150x4. I’m looking for a pair of quality coax that can comfortably handle 80-100w as stated in my OP. Thanks for the suggestions.
Ouch...I'd caution you in thinking Dayton not being a quality driver. I run them in multiple positions and they easily EQ better than my 4-digit price Focals. In fact, I thought like that before. Thinking that a less than $50 driver could hold a candle to my thousand plus dollar drivers was laughable at best...until they were better, and I could go through 10 sets of them before even reaching 50% of the cost of the high end, name brand guys. But it's your car brother...and more importantly, your money. If you must have a name brand driver in there...go for it.
I'll make you a bet though. I bet if I posted some frequency response graphs of several various drivers without posting the names, you be HIGHLY surprised at what outperforms what.

The only 5.25 Dayton neos I could find come in at 40w RMS. My current JL’s already get 75w clean JL amp each. I already stated I’m looking to make the system louder while keeping the sound quality also again, Im already set to get a Hertz amp with 150w per, I also like coax in that spot as long as the tweet is smooth. I’ve heard quite a few very nice, high amped systems in others cars with morels and they don’t disappoint, they’ve earned their reputation. I can’t think of any killer systems sporting Dayton’s so I’ll go by what my ears tell me.
If you’re happier with the Dayton over the focals you should sell the focals and get the Dayton’s. For less then $300 I can buy very nice morels that I’m sure will sound great at the power level I want and it won’t break my budget. Really don’t care to bet you but thanks again for your opinion.
I'm with Ronin here. The rear speakers really don't contribute that much to sound QUALITY, and can quickly confuse any good work you've done on the front stage. In my car, I took what I would have spent on rear fill and added it to my budget for a good front stage (I run Morel titanium components with my own hand made crossover network on a JL amp) and forgot all about rear speakers or extra amplifier channels. It can still get uncomfortably loud while remaining crystal clear. More is not always better.
But he does use rear speakers none the less, he said to use midrange drivers and not coaxial but that’s irrelevant to me. There are many different schools of thought on the subject and we all like what we like. I happen like components up front, coax in the mid and sub out back. That’s what’s been in mine for years and just looking to upgrade the backs. To each his own.
Just got off the phone with Crutchfield after ordering Morel tempo ultra Integra 502 coax’s. They RMS at 100w per. With silk tweeters with many good reviews on their smoothness I’m confident that they will sound quite nice and will take all the juice I will feed them on occasion. Unfortunately they will have to wait to to be heard, I just winterized the car and tucked away till spring. I hate winter.
I was looking for something and came across this thread I started. Figured I’d update it since I did the install about a year ago. Installed the Morels but couldn’t get the Hertz amp, it wasn’t available anywhere for quite some time, Covid I assume. After much research I decided on the Audio Control 4.800 unit. It delivers 125w at 4 ohms for 4 channels. Class D so it’s small, doesn’t get hot and lays down the juice. Have Hertz HSK 6.5 components up front and the Morels out back. The Hertz components really shine up front and get super loud and clear and the Morels are even better than I thought they’d be. They really complete the “wall of sound“. They are powerful and crystal clear at all volumes yet super smooth with that silk tweet. I love it as is and everyone who’s been in it and appreciates quality sound does also. Its well know some of you here( or used to be here) don’t like them out back but no need to comment.

Came across this thread doing research for my C6, thanks for the update. Did you have to modify the openings to fit the Morels?

you’re welcome, I’ve done a lot of research myself here to formulate my own needs and wants and I’m more than pleased with the results. As I said it was about a year ago they were installed. I called Crutchfield and spoke to one of their guys and he said they would indeed fit. I didn’t do it but if I recall they went right in with no cutting or anything substantial. There was no discussion with the shop of any issues and they were installed quickly with no extra cost. If you give them enough clean power I’m confident you’ll love them.
