infinity speakers are awesome

After hearing the amazing sound quality of my wife's 2017 Ram Laramie Infinity system I decided the Challenger was due for an audio upgrade.
I was going to upgrade the 730N head unit but thankfully decided to initially do the speakers only, and the head unit is still good but the nav display is dated and the sirius interface is a little cumbersome...2010 technology.
I installed Infinity Reference REF-9632ix in the front doors and Infinity Reference REF-6532ex in the rear tray.
The factory speakers felt and looked cheap compared to the infinity model, the new speakers were two or three times the weight of the factory model. The magnets were much larger, but they still fit in the factory location.
The sound is so much more clear, and the increase in bass is enough (for me) that I don't think I need to install a sub in the trunk.
I would definitely recommend these speakers, I purchased the kit from crutchfield which included the adapters so everything plugged in (no cutting & soldering needed).

Nice, Infinity makes some good speakers at a reasonable price.

In my experience the Infinity Reference line of speakers is the perfect aftermarket replacement for stock speakers. They sound great even when powered by a stock head unit, and they can handle a reasonably sized amplifier as well should that upgrade happen later on.

On the subject of the stock speakers, yes they are the bottom of the barrel in terms of quality, and they sound like crap when powered by the factory head unit. However, they can be made to sound decent if a small amp is used to power them. Although I will admit that in most cases it is much easier to just to replace them with quality aftermarket ones than it is to wire in an amp to power them.

I would say absolutely.

You will get the best bang for your buck if you match the speakers’ RMS wattage needs to what your system is providing, and that depends on whether or not you have a factory amp. If you don’t, get the speakers rated for lower RMS, 50w and below. If you do, you can go for the speakers in the next range up for RMS wattage, and they will sound outstanding.

I love the HK system, but sometimes I find the door speakers aren't up to it when I turn up the volume. If you decide to go this way with Infinity speakers, let me know what speakers you replaced and with what model.

Just for kicks, I looked at Crutchfield's website for Infinity door speakers for the HK system. My eyes glazed over.

If we're talking Infinity Reference speakers for the Challenger, here's what you're looking at (listed in order of importance of replacing, IMHO):
1a) door drivers (factory h/u pushing speakers) - https://www.crutchfield.com/p_108R96...EF-9632ix.html
1b) door drivers (factory amp pushing speakers) - https://www.crutchfield.com/p_108R96...EF-9633ix.html
2) rear deck - https://www.crutchfield.com/p_108R65...EF-6532ex.html
3) dash corners - https://www.crutchfield.com/p_108R30...F-3032cfx.html

NOTE A: 1a vs 1b is an either/or situation depending upon what is powering the speakers now (and what will be powering them after replacement). I do not know if the factory Harmon Kardon systems have a factory amp, so I put both. If it does not, go with option 1a. If it does, go with option 1b.

NOTE B: replacing the 3.5" speakers in the dash is not absolutely necessary IMO. Some will say do it since you are replacing the rest, but I do not believe the price of the replacements justifies the minimal upgrade in sound if powered by stock head-unit. It's up to you though, they will help the overall sound somewhat.

Nuke! I would love to do this. My R/T is a base with just a CD player and radio...would just like to switch out the speakers. But man looks like a pain in the but to get the door panels off? Also is it still just two connections on the speakers?


For my surround sound in my home theater I have older Infinity Studio Monitors for all my speakers and movies sound awesome!

Also, how involved is it to get to the rear speakers in the rear tray? I definitely want to look into doing this real soon.

They aren’t too bad. I guess it just depends on how mechanically inclined you are. If you mostly do your own work on the car, getting the door panels off and back on isn’t going to be a big deal. Check out this write-up for some tips and pics: https://www.challengertalk.com/forum...wesome-663027/

They are a little more cumbersome to remove (not to get to though, that’s not too bad) due to the back glass being right above the screws holding them down. So you have to get creative with those puppies.

There’s various different methods I’ve seen used and used myself. The one I like is using a 1/4” ratcheting wrench to turn a Phillips head driver bit, but there are other options. Check that write-up above for some more tips on this one.

You can always leave the speakers as-is and just add an amplifier. That’s what I have done with my Charger, and it sounds great. Although I will admit the whole process was way more work than just replacing the speakers, but the speaker option was not a good one for me because of <reasons>.
