4th Gen JBL replacement

Actually its possible to remove the jbl amp entirely on the 3rd gen. The rockford dsr1 enables you tonuse aftermarket amps with the jbl amp removed. So for they don't state if it works on the 24+ taco's yet

 

Who built this box, and would it be possible to get about three quarters of a cube from just one side to leave the other side for storage?

 

its a box by ground shaker....
They have a 10" & 12" option, you need all the airspace you can get to get good sound,
I personally wouldnt waste funds with the single 10"....
Also they have 2 versions of the box for both 10"&12", one cutout specific to the JL TW3, & the other for any other shallow mount...
Theyre actually using the passenger side of the truck to get the .9 cubic feet of required airspace also, it's not just a decorative upper panel to make it look cool....

 

Is there a factory amplifier in the Non-JBL system? or can the Audison C8 amp be wired directly from the head unit?

 

my guess is you still need a PAC ap4 ty 14, so youre not butchering all your wires, & helps keep a good signal....

 

There's some great info in this thread for both JBL and non-JBL owners, but I think it'd be useful to have a separate thread so people don't get confused when working on their system.

Did work on mine over the weekend. Morel Maximo ultra 3 way components up front, coax in the rear. On an audio control d4.800 amp.

Used a PAC AP4-TY14 for line output

WHY DID TOYOTA USE MOLEX CONNECTIONS BETWEEN THE DOOR AND THE BODY? Couldn't run speaker wire all the way into the doors. You need to splice into the factory wiring.

Took some time, but figured them out. In the kick panels and the B pillar there is a pair of wires that are twisted together. Those were the speaker wires for the door speakers.

I've got the iforce max, so storage in cab is super limited. Didn't want to put amp behind the rear seats and lose storage. Amp fit perfectly under the passenger seat, resting on the plastic rail the factory seat wiring attaches to.

Ended up drawing and printing some brackets for the mids in the dash.

Link for brackets of anyone needs them.

 

Too late now but taxxo tunes sells speaker connectors for the 24-25...

 

So if I want to do a full sub replacement behind the seats, does anyone know the panel part number to replace it? I haven’t torn it apart yet but would it be a modest cost, one or two panel replace or am I looking at busting out the sawzall and redoing that whole space?

I want to run a slim 10 back there and don’t want to go under the seat if I can avoid it.

 

They do, but then how do you get from the AMP to the speaker?

 

PAC APH-TY02 harness. Connects at the JBL amp under the drivers seat, and makes a T-harness. Use some 8-conductor speed wire, and make the connections from amp to speakers.

 

What gauge speed wire did you get?

 

So I just picked up my '25 Tacoma with "Upgrade package". I noticed that the two front door speakers have sound, only very low bass...no midrange at all. Vise versa for the two rear door speakers. Is this normal for the JBL system with the 14" screen? Seems like something is amiss. I'm certainly no audio/car stereo expert, but that doesn't seem right. Thanks in advance everyone!

 

Yes, in many JBL systems Toyota uses the lower front door drivers for bass. The midrange comes from the dash.

 

Oh...OK. Thanks Bear! Am I stuck with that layout, or can I swap out the front door speakers and get better/fuller sound quality?

 

Only comes in a bundle of 9 at 16 or 18 ga per. Can’t link from my phone right now. Google “T spec speaker wire”, should be the first two results.

 

What you’re describing is normal. The dash speaker is the midrange, where voices come from mainly. The pillar speakers are tweeters, where cymbals come from mainly. The mid bass in the doors is just that. It plays the low frequencies that the subwoofer or the dash speaker can’t play. It’s also where Toyota pumps in the “fake engine noise”.

 

Does the speaker in the front door only reproduce certain frequencies from the head unit/amp, or is the signal to those speakers only of a certain frequency? Would swapping out the factory low frequency response speaker to a wider coaxial speaker reproduce a wider sound? Sorry if this seems like a stupid question.

 

It's hard to know for sure without doing some testing. But the speaker in the door is likely only receiving the mid-bass frequencies and replacing it with a coaxial would not give you a full frequency response.

 

I can confirm this. Bought 2 sets of Infinity Reference REF607FSL 6 1/2" speakers and did a side by side compare by installing in the passenger door and then playing a known track. To better isolate the difference, I faded the sound all the way to one side then the other so the mix was not throwing the comparison off. For the front doors, the improvement was very minimal because only the lower frequencies were being sent. The stock speakers are actually pretty good in this range.

The rear doors are a completely different story. These Infinity speakers made a WORLD of difference. So much better sound quality and balance with the improved mids and highs in the back doors. It was the biggest improvement I've seen in a stock sound system for under $115. Waiting on my Beatsonic to get here to see if it makes even more improvement.
