I replaced all of the upgraded Alpine speakers, except the sub. I added a five channel amp. All of the speakers are 2 phm (2.3 to be exact, my installer tested them.) After much false information from installers that 2 ohm speakers are hard to find, I state for all 2 ohm speakers are easy to find at Best Buy or Crutchfield. The door speakers are 6x9 but you can also replace with 6.5 round ones. The Alpine door speakers are polymer woofers, so you have four woofers. That's why the Alpine system sounds so muted, the speaker built in cross over is only letting low notes play. So just replacing these with coaxial or triaxial speakers (my first step) will give you much better full range sound. The Alpine amp is sending full range sound thru the wires to the door speakers. Many may be happy at this step. the Alpine sub seemed fine after these steps. Next, I replaced the dash speakers. These are 3.5" round at least 42mm deep paper cone speakers. The Alpine amp is programmed oddly, on YouTube a guy posted the frequency response as a video from his testing bench. After replacing all of the speakers, it seemed to me that portions of the mid range sound range were missing. But I am picky. So I replaced the Alpine amp. The Alpine amp is not adjustable by the user. I did get a full range of frequencies after this. The new amp is 1000 watts. The Alpine sub is taking about about 300 watts now (the Alpine amp only put out 368 watts for all the speakers) and doing fine. I may yet replace it since I have come so far. It is ok but not really covering the deepest notes. I like dance music. A bass should sound guitar like in that you can hear the notes change not just thump thump thump. It took me forever to gather the above information. The only thing I do not know, is the size of the sub. I am guessing 8" but it could be 6". It is in a special sub box, elsewhere I have posted a picture from the Alpine website Dodge page. I hope this helps folks.

The dash speakers are standard 3.5" speakers and can be at least 42mm deep. Just replaced them in my 2015 Journey.

I picked the picture with the five tweeter speakers from the Journey site as that it why I think it sounds bad, only two of the five made it to production. Is it not odd, my picture is on the Alpine site? Any hoo, changing the door speakers first, made a big difference. The Alpine amp does send an almost full range signal to the door speakers so new coaxial or triaxel speakers will add mid range and highs to the new door speakers. I would try that first and see if you are happy as you just use the existing wires. The Alpine amp does have issues with the range of frequencies it sends out, a person posted a YouTube video of his sine wave test and it had issues. So bypassing/replacing the amp has benefits. I had my new five channel amp installed at a audio store, so I cannot say how they wired it. I know they bypassed the Alpine amp and added item that reassembled all the frequencies before the signal went to the new amp. It was $450 to have the new amp installed. As for the sub, somewhere on this site a guy noted it was 8" and that you could get a 10" in with modification. I agree with others there is not much room so any new one to replace the Alpine sub would need to be among the thinnest available. Looking in the cargo area, it looks like there are two 6x9 speaker openings, as there are what appear to be speaker grills/openings, the sub is behind the drivers side. The one on the right must be just decorative.

I modified my inital post, to show the picture of the equipment laided out on Alpine's web site at www.experienceapline.com/dodge/

I have no idea if they had to run a power cable or if they used the former factory amp power cable. The new amp is 1000 watts, five channels. The new amp is in the compartment in the cargo area by the lift gate, in the floor.

I love these forums. I had this happen last evening. Pushed the door lock button on the door, closed it and I got the three horn beeps (lights flashed as well) and the doors unlocked. Did anyone ever figure it out?

In my 2015, the Alpine amp is under the passenger seat. My new amp was installed in the shallow box in the cargo area nearest the lift gate. It is a 1000 watt five channel amp that accomodates 2 ohm speakers (or 4 ohm.)

I replaced the dash speakers with JBL GTO329 3.5" diamater 1.5" deep coaxial speakers. These, along with a new aftermarket amp have served to address all of the issues I had. I left the Alpine sub in place and it sounds great. Sirius sounds fantastic (I listen to Sirius a lot.)

The primary advantage of the upgraded sound would be 1) it is easier to add an after market amp if you have the upgrade 2) you get the special custom subwoofer enclosure in the rear cargo area, 3) you get the better radio option (hard to replace/upgrade aftermarket wise, if at all) and 4) some do like the Alpine system. I have read the Apline sub is not a bad one it is just getting bad signal from the Alpine amp and possibly underpowered. I will know soon. I have yet to change the sub, and it is being connected to the new amp.

The dash speakers are at least 42mm deep and 91mm round. I just had them pulled out and replaced.

I replaced all of the speakers except the sub (so far.) I also replaced the amp. I do think you could move thru steps as you may get to a spot you are happy with - without going further. I would start with the front door speakers. You will see a big difference. Then back doors and/or dash speakers. The factory amp seems to put out decent power.

All of the speakers are 2 ohm (2.3 to be specfic.) I replaced the door and dash Alpine factory system speakers, except the sub woofer. The dash speakers are 1.5" deep and 3.5" in diameter. The door speakers are 6X9's. The sub appears per Alpine's site and other posts to be 8" enclosed in a special design box.

Just left the installer swapping out Alipine dash speakers. I picked JBL GTO329's to go in. They fit. These speakers fall into the 1.5" depth category that I was guessing the factory speakers to be sized. I do not know how deep is the max (the installer forgot to check.) These speakers have a diameter of 91MM. They are coaxial. The speakers that came out appear to be a plain full range speaker, with a poly cone, built on crossover. They were covered in black speaker fabric. Woo hoo, the depth question has been partially answered. There are many speakers in this size, but fewer that can handled a lot of power. My new speakers are 25 rms and 75 peak power.

I replaced all of the door speakers already, I have enough tweeter, I want more midrange.. I soon will be able to share the available depth.

Dhh3, your insights have helped many and I understand you like the sail panel tweeters. I want more mid range and thus seek to replace the dash speakers. Your insights as to diameter helped but your pictures don't show the depth. I have searched widely for the depth of the dash speakers. I posted here, as many looking to buy a Journey look here. Something fits as something came out. Otherwise I like my Journey.

Having spent weeks diving into the system, it simply has a silly design and is worse than the stock system. It is designed with the four door speakers serving as woofers with low pass filters on these speakers. There is a subwoofer in the cargo area. The two dash speakers have high pass filters. It sounds like a muffled hot mess. Folks in the 2nd or 3rd row seats will hear only muffled rumbling, not any sense of music. Sirius is unlistenable it simply sounds horrible. I got the upgrade as it is easier to get aftermarket gear if you do so. How can Dodge claim it meets their standards as well as those from Alpine with any semblance of a straight face? On Alpine's Dodge site, some photos show five of the dash speakers suggesting along the way three were deleted from other locations. Replacing the door speakers with triaxel speakers greatly improved the sound. The amp has no on board controls nor is there a way for the consumer to change the firmware. The subwoofer feed needs to have some db increase. Trying to find out the dimensions of the dash speakers is fruitless (I will waste time and money with an installer to finally figure out the size of the dash speakers and promise to share, take that keeper of the secret dash speaker size.) Alpine should be embarrassed its name is associated with this very subpar system.

I know they are 3.5" and the cutout size is a tad less than 3.2. But the 800 lb gorilla is how deep are they (or how deep can they be?) Any insights deeply appreciated. I have the awful Alpine upgraded system, that I am ripping out starting with a new amp and all the speakers. I want to instal coaxial speakers, not just tweeters.

Jumping off a cliff. Ordered JBL GX 303 3.5" coaxial speakers for the dash. The diameter for install is @3.1" and the mounting depth is just under 1.5" the shallowest one I could find at the 3.5" size. They are 2.3 ohm so they will match the ones being removed. Stay tuned.

I bet you are the one who replaced the dash speakers. Am I correct? If so any insight as to the depth available for a replacement speaker? Also, thank you for the amp insight. I suspect replacement of the factory amp is in my future. I would venture to say most folks would be happy with just new door speakers. The system sounds pretty damn good now, but I am a audio guy and in my case the system is just not where I want it to be to make me happy.

The Alpine site showed the subwoofer as a round speaker. I have seen others post it is an 8" speaker and used in other Dodge products where it sounds much better. The amp seems to be the reason it is not so great in the Journey. the amp settings as to what it sends to the speakers and sub suck. I found a guy who tested the signals and posted the results on YouTube, it seems the factory amp does not send out various sections of the full sound range frequency. It does seem the amp, thru some process unknown to me, can have its firmware adjusted. It would be nice if the dealers could do this, my dealer say they do not have that ability. Going thru most every post about the Alpine system, I found posts that talked about firmware service update posts that seemed to suggest problems had been found and there was some way to get the amp updated. Sadly, no clues as to how that was done. If the Dodge moderator is reading this, so many would be so happy if the could take the amp to the dealer and have the ability to change the amps settings to match their preference.

I have some answers to some of my questions. I found a link to the Dodge page at the Alpine site. One picture shows all of the audio equipment laid out on a table. There is not a sub amp, unless it is in the sub speaker box. All of the door speakers were just woofers, that's why they sounded so muddled. Still not able to get a clue as to how deep the dash speakers are, which makes them hard to replace. I have seen folks say in other posts, the dash speakers are funny shaped. They are not (both from the pictures at Alpine and from the pictures in a post where someone had removed them) they look to be normal 3.5" speakers more telling, the Alpine picture with all of the equipment laid out, shows five of the speakers used in the dash (I bet other non dash speaker locations were in the mix at some point.) Granted in the visual showing placement locations only two of the five appear, in the dash location. I suspect from design to production, someone cut out three speakers. The signal from the amp to the door spears is not low pass (only sending bass) the speakers are low pass (only playing bass.) That explains why just replacing the door speakers makes such a difference, you get mid range and highs to go with the bass. That all said, you likely could just replace the front speakers and have great sound or add mid/tweeter speakers keeping the door speakers. Ending this with a plea for any information as to the depth of the dash speakers. Replacement of the dash speakers is my next goal. I want to find 3" speakers (thus the will fit the slightly less than 3.5" diameter of the current speakers, that are 2 ohm so they match the ohm of the current speakers.) I have called a few Best Buy installer folk to see if they have insights and found no answers. I am holding off on replacement of the amp, until after I replace the dash speakers.

Rooting around the various posts about the Alpine system, I found a link to the Dodge Journey page at the Alpine site. Welp, the Alpine site has pictures showing five mid range/tweeter speakers laid out with the door speakers, amp and subwoofer. Having five of the mid/tweeter speakers would have compensated for the four woofer speakers in the door. Granted, in other pictures where they show speaker placement, only the two dash mid/tweeter speakers are shown. The site does confirm the door speakers are woofers. It seems silly to have four woofer speakers in the doors, and just two mid/tweeter speakers in the dash. This arrangement explains why the sound of the upgraded Alpine system sounds worse than the standard system and so muddled. Thus, I venture to say somewhere along the way from design to production some heartless non caring soul deleted three mid/tweeter speakers from the production models. Take that Mr/Ms Dodge moderator and see if this clue helps explain why so many owners are ripping out the Alpine upgrade and replacing it with aftermarket equipment.

I have confirmed some of the Alpine system amps do have problems. I got the dealer to replace mine as it had a firmware error. I had the dealer sit in a similar model on the lot to compare it with the sound of my system. I replaced all of the door speakers with JBL GX series 6X9 speakers. These were 2.3 omh, the same as the speakers removed. They are triaxel and $100 a pair, so $200 for all four at Best Buy, $150 to have all four installed. No more muddled sound, Sirius is enjoyable to listen to, the door speakers play mids/highs and the bass response vastly improved. For the next step, I cannot decide if replacing the amp is a good move. The installer at a Best Buy says any amp I select will result in losing the fade function, is that true? I am hoping if I replace the amp, I can increase the impact of the Alpine subwoofer - am I misguided about the subwoofer objective? Is there a separate subwoofer amp? If so does any one know where it is? If there is one can I just replace that subwoofer amp? I did see in one forum post a picture of the not so great dash speakers. The member said they are slightly smaller than 3.5 inch but he did not say how deep they are (he installed a much smaller tweeter.) Does anyone know how deep the dash speakers are? I have searched around and it seems there are some possible tweeter replacements but they vary in depth. I would prefer a larger speaker for the dash than the ones the guy who posted the dash speaker pictures used. Any insights greatly appreciated.
