4Runner’s Dash Speaker Upgrade for Better Audio Quality

Dash Speaker Swap 5th Gen 4Runner

Swapping out the OEM dash speakers with a coaxial speaker, that has a woofer cone, and integrated tweeter

Most everyone will admit that the 4Runner’s audio system isn’t horrid, but it does have much to be desired. I personally find upgrading an audio system a little daunting, with all the speaker combinations, audio processors, subwoofers, I wouldn’t even know where to start.

However, until I commit to a full system upgrade (like from OEM Audio Plus), I chose to start small and test out swapping my OEM dash speakers with a much better coaxial speaker, that has a woofer cone, and integrated tweeter. These new speakers will add a higher bass output, and enhanced midrange performance.

With all the seat time I am logging in this 4Runner, going camping, exploring trails, or even in my daily commute, I didn’t want to settle for “meh” sound, I want great sound.

So for $47 bucks, I figured, why the heck not?

Let’s begin.

  • Install Time: 3-5 Hours
  • NOTE: This is not a direct Plug and Play swap, cutting and imagination required.

Parts Used:

Tools Required:

  • 10 mm Socket wrench
  • Socket Set
  • Tin Snips
  • Masking Tape
  • Cutting Dikes
  • Butt Connectors
  • Heat Shrink
  • Needle Nose Pliers
  • Flat Head Screw Driver
  • Electrical Tape
  • Wire (18 Gauge)
  • Solder Tool
  • Wire Cutters
  • Spring Clamp
  • Female Wire Disconnects (not pictured)

NOTE: Installation follows the Passenger Side, which is slightly more difficult. Same steps will be taken for the Driver’s Side, which will retain use of both OEM speaker mounts.

PART 1. Removing the Stock Dash Speaker (Passenger Side)

Step #1: removing the stock dash speaker grille

Step #1: removing the stock dash speaker grille

Start by removing the stock dash speaker grille. You may use an interior trim tool here, however, I was able to work a small flat head screwdriver in the gap, and proceed to pop off the two front clips.

TIP: I used electrical tape on the end of the screwdriver as to not scratch the factory dash.

Step #2: remove the two bolts holding down the factory dash

Step #2: remove the two bolts

Using a 10mm socket wrench, remove the two bolts holding down the factory dash speaker to the speaker mount.

Step #3: Remove the factory speaker, and unplug it from the OEM connector.

Step #3: Remove the factory speaker

Remove the factory speaker, and unplug it from the OEM connector.

Step #4: Remove the factory speaker mount with 10 mm socket wrench.

Step #4: Remove the factory speaker mount

Step #5: mask off the area around the speaker

For the rest of the installation, I masked off the area around the speaker as to not scratch it while installing the aftermarket speaker.

PART 2. Reusing the Speaker Connector

Step #1: remove the blue OEM connector

We will want to remove the blue OEM connector off the OEM speaker, this will help us connect our new speaker to the OEM connector.

The blue female connector is held onto the speaker by several clear clips. Using a set of cutting pliers, cut off the clear clips. The only thing holding the blue OEM connector to the speaker now is an adhesive. Work a flathead screwdriver between the blue connector and OEM speaker, breaking the adhesive bond and fully separating the two.
Using the cutting pliers, cut the two wires as close to the OEM speaker as possible.

Step #2: Removing the OEM Crossover

Working the OEM crossover out, remove with needle nose pliers. With the OEM crossover removed, I was able to solder a bypass between where the factory crossover once was.

Step #3: Building the New Harness

Gently strip the ends of the two wires from the OEM blue connector. Lengthen the factory wires with new wires, solder ends, and add heat shrink. Repeat to other side.

The Infinity 3022-cfx I used recommended the used of a supplied crossover. I attached the new crossover inline, with the same black wire of the previous OEM crossover, using butt connectors.

Also supplied with my infinity speakers was an adhesive foam strip to add around the edge of the speaker. I chose to add mine, whether or not it will make a difference for our application.

Step #4: Modifying the OEM Speaker Bracket

Using a pair of tin snips (or another comparable tool) cut away at the factory connectors to help adapt our new speakers to fit in the dash location. The driver’s side and passenger’s both differ and will require different cuts to assure fitment.

Step #6: Attach the new harness

Step #6: Attach the new harness

Attach the new harness to your aftermarket speaker and prepare to install in the vehicle.

PART 3. Installing the Aftermarket Speakers

PART 3. Installing the Aftermarket Speakers

Driver’s Side: Reinstall the factory speaker mounts using 10mm socket. Connect factory audio harness to the blue connector, and gently place into the dash, lining up holes of the factory bracket and new speaker. Reuse the factory 10mm bolts and tighten down with 10mm socket wrench. Lastly snap on, the speaker grille.

Passenger’s Side: This is where things get creative. Utilizing one of the OEM speaker mounts (previously the passenger side right piece of the speaker mount), invert and attach to the left side of the cavity, into the dash, tightening down lightly. Connect the OEM harness to the OEM blue connector, and gently feed into the dash. It’s a tight fit, but there is a cavity that the wires will slide into. Gently place the new speaker down into the dash. The left side will line up with the factory mount that we modified, and the right side of the speaker will line up with the threaded hole in the dash that was previously for the OEM mount itself. Tighten down all three (two screws and one bolt) with a 10mm socket wrench. Lastly, snap on speaker grille.

NOTE: This side is open to interpretation, others have made their own bracket, extending the holes for better fitment. However, I was able to still achieve fitment by reusing the OEM bracket. With the new speaker sitting slightly higher, it will be a snug fit. If you would like a little more piece of mind knowing there is a gap in there, you can shave down the plastic ring under the speaker grille.


Replacing the dash speakers solved many of the problems with the OEM audio system. Before, the old OEM dash speakers, sounded muddled and cruddy, diminishing further in quality at higher volumes.

After swapping out the OEM tweeters, I am pretty impressed by how much the audio quality increased! The largest improvement I noticed has been in music particularly containing guitars, drums, piano or strong vocals. Overall, these speakers transformed the muddled crud of the highs and mids into a sharp, crisp, detailed sound. I was surprised how much detail I was missing out on with the previous OEM tweeters.

One of my favorite tracks to test was Queen’s Bohemian Rhapsody. I was amazed at the general increase of quality as the whole track played. Freddy Mercury’s voice was clear and sounded as if he was right there in front of me. The drum kit and cymbals were detailed, sharp, with a wonderful crispness with each hit. The audio even retained its quality all the way up to max volume.

Is it worth it?

Yes. For me, the benefits of this mod far outweigh the cost or time I put into the installation. With my investment into this mod being under $50, the most challenging aspect was the latter. Keeping in mind that this is NOT a plug-and-play application. The most difficult part was fabricating a new speaker harness and fitting these much larger 3.5” coax speakers into the small dash area. In the end, installation time pales in comparison to the future hours of enjoyment I’ll have with a better sounding audio system.

Nice write up! I have a new to me 2016 4runner and I did this install with the Infinitys today. I couldn’t figure out how to make the brackets to work in any configuration. I used a piece of sheet metal to make my own bracket for the outer side and just screwed the inner side down opposite of your right speaker adaptation. It worked out well with no need to cut/grind down the plastic covers. I made adapters and used supplied capacitors as per your instruction or close to it. I put infinity 6x9s in the doors as well… Read more »

I’m using the Taco Tunes harness they supplied. It has 4 wires (2 positive, 2 negative) for the tweeter harness. Do i only use 2 of the wires (positive & negative) and leave the other set? I would wrap them with electrical tape.

I got my own question answered by Taco Tunes for anyone else needing guidance on this:

Join together the 2 wires positives together into your positive on tweeter.
Do the same for negatives
So your tweeter will have 4 wires going to it. 2 for positive. And 2 for negative
Black and stripes are negative. Solid red and white are positive.

Hi Frank long time listener first time commenter. Your page is amazing firstly!

I have a 2015 limited which has the JBL system. I wonder if this works with that. Any insight?

Does this work for the new 2020 TRD Pro with JBL’s?

Great write up, thank you!. May I ask do I see a crossover already soldered to the speaker? If not, what is that used for? I bought similar speakers with the same thing attached, and they didn’t come with supplied crossover. When I tried my new speakers with or without the factory crossover, I cannot hear any difference.

Hey Frank, thanks for the tutorial. It was nice to have one source for the full install and some guidance on modding the mount for reuse.

Did your speakers come with that 220uF capacitor? I think that will be filtering lots of audio that the speaker is capable of handling with the power of the stock headunit. The 4.7uF cap should be all that’s needed to filter out audio below ~133Hz.

Just did this mod to my 2019 TRD 4WD Premium 4 Runner using the Infinity speakers shown here. Didn’t add the extra capacitors, they came with some already installed. I used 3 Stanley flat pieces of steel from Home Depot with holes already drilled in them so I didn’t have to cut up any original parts. I carefully bent the little strips of steel so they kept the new speakers at about the same elevation as the originals. Screwed the one in directly as shown in this post. I also bought the wire harness from Taco Tunes. After all the… Read more »

There are dash speakers that are plug & play that takes about 10mins to install. That’s what I did.

Hey Frank. I truly appreciate all the info you have compiled on this website.

I am going to attempt the install in a few days. Do you think the TacoTune harness is needed? Also, is there any way to contact you quickly if I have an issue? If not, no big deal.

Thanks again.

Thank you for the detailed writeup, I followed this using the TacoTunes wire adapters and a set of JBL Club 3.5″ speakers and it came out great!

I received the harness. Which two did you use to hook up to the speaker or doesn’t it matter? My harness has a red and white for positive and black and white/black for negative.

Did you use the capacitors? I have the jbl club speakers for this mod coming too. How does it sound after the install? Vocals good? Good replacement for the stocker tweeter functions?

Frank, you mean you used the Infinity “stock” capacitor correct, not the Toyota crossover that came off the factory speaker harness? I think I’m getting ready to do this as well. I like the Tacotunes 12″ subwoofer but I have the Rago panels so I think I have to come up with something else for a subwoofer.

Did you put a bass blocker in? Looking at a few other threads about a front speaker upgrade and a lot of people are saying putting a bass blocker in helps the sound a lot. What’s your opinion?

any rattling or speaker coming loose. p.s. great job explaining

What size and kind of speakers do you recommend for my 3rd gen 4runner?

July 9, 2018 12:24 am

Seems these REF-3022CFX are not made any longer, I did find these REF-3032cfx just not sure of the difference.

July 15, 2018 1:57 pm

did you use the existing capacitors or do I need to buy ?

Nick, I am interested in the Harness that you are mentioning to make this a little easier. Could you send me a link to the exact one you are referring to? Thanks in advance
