No Bass in JBL Rear Subwoofer & Rear Door Speakers

[The_Dark_Knight_Forever]

If I move the fader to the rear a couple of notches, I can barely hear anything.

I'm not expecting Skar sub levels of bass, but there isn't more than a faint whisper coming out of my subwoofer or rear door woofers (the tweets high in the back doors seem to work okay though).

This is also how my system is also.

To me that sounds like you need to head to the dealer then. You might have a problem with an amp or something unplugged

Mine is not like that at all although, the amp that comes in these doesn’t seem to do much until you get it up to 35.

If you’ve turned it up and you are only a couple notches back and don’t hear anything, I would suggest heading to the dealer to have it checked

does anyone have buzzing noise from their jbl speakers (any of them) when the audio is muted? you can hear it if the cabin is really quiet or putting your ear up close to the speakers

No. My background includes audio processing engineering. I hear nothing like that in my ORP.

went and tested the subs in my platinum here is the sound clips.

1st clip : 2025 4R Platinum rear bias full bass
2nd clip : 2025 4R Platinum center bias full bass
3rd clip : 2023 Tundra Platinum rear bias full bass
4th clip : 2023 Tundra Platinum center bias full bass

you can definitely tell the difference in bass punch in the rear on the tundra vs the 4R and center is even more dramatic

Isn’t the stock subwoofer size for a tundra a 10 inch sub versus the 7 inch in a forerunner?

Remember, its stock...dont expect a thump.

I didnt hear much at first either because the front speaker was so overpowering. Move the listening area back a couple of notches, Turn up the bass and try again. See if that helps.
It's probably there... just crappy due to the fact that its a 7" tiny sub.

The rear speakers are 4". You'll never hear bass out of them no matter what you do.

Moving the fader back a couple of notches & turning the bass up should not be necessary to have a “premium” system sound like it should. At the default center position, the sound should be ideal for the vehicle the system is installed in & all speakers should be playing audibly. The center fader position should provide the most equal volume of sound from all speakers where as moving the fader front or rear, left or right causes reduction of the volume of sound from the front, rear, left or right sides depending on where the position of the fader is adjusted to. Ideally there should be a separate subwoofer level control in the EQ but questionably there isn't.

I started this thread because my rear speakers (doors & subwoofer) are practically not playing any bass of what would normally be expected & acceptable by most people. I'm hoping we all can put our heads together & find a solution for the problem rather than just saying “don't expect much from a stock premium system & it's supposed to sound that way”. I'm seeing in this thread that others are experiencing the same problem with their systems also & the more people who positively contribute to this thread subject means that we can answer questions and/or find solutions to the frustrating problem we affected owners are having.

I'm not a newbie to car audio as I've put together nice aftermarket systems in my previous two vehicles. I know that stock premium system won't be as robust as a custom aftermarket system but I also know that having a premium JBL system should be very sufficient & perform much better than the way mine & others' systems are now. Time will tell how it gets resolved & how much of a pain in the ass it'll be to resolve it.

its not really like static but maybe like white noise? its a noise when the audio is muted, theres a slight hint of the noise when the music is set to a very low volume. I hear it more on the speakers located on the dash and the rear door top speakers but not the removable speaker

My 4Runner is scheduled for amp replacement on Monday . Will report back here the results .
Fingers crossed .

I'm looking forward to seeing your post following your amp replacement! Thank you in advance!

I'm am curious though about the amp being under the driver seat. I've seen those amps (I forget the brand) that gets installed in the dash directly behind the infotainment display. Do we have an amp for the front (in the dash) & an amp for the rear (under the driver's seat)?

Not to argue but turning my volume knob up to 24 to 30 with the windows up is pretty sufficient for my ears. I know the system volume max is 63.

wait is there any audio equipment under the front passenger seat? I have a dash cam battery pack tucked there not sure if thats causing any issues I dont think so.

For some reason you seem upset.

People here are just trying to help. There’s no way for anyone here to know whether you are a newbie or not.

I was suggesting you do that so you can see if it’s really playing or if you have an issue requiring a visit to the dealer, because some people don’t know how to diagnose systems on their own…..but it sounds like you do.

Overall, premium is sadly just a word. It’s premium and better than the non-premium system, but not necessarily “high-end.” . There are very few “premium “stock speaker systems that sound very good or give a hard punchy base these days and there are many people that purchased a vehicle, expecting it to sound like a high-end system simply because it says “premium”.

It’s like the B&O Systems that Ford is using now. Normally, they are a phenomenal brand, but if you look at what Ford puts in, it’s a cheap, thin, small paper cone with almost no magnet. “Premium” only by the fact that it’s a smidge better than the non B&O.

My Off Road Premium JBL system sounds perfect. Hope you get to the bottom of the issues you're having.

My reply was not intended to come across as me being upset however I don't agree that the premium JBL system is designed to not have some punch from the rear speakers. I appreciate those who have taken in interest in this subject & problem that I & others are having with their systems. All respectful comments are appreciated even if the opinion is different.

My thing is that I know the system had some nice bass to it when I first bought it & now it doesn't for some unknown reason. Others are experiencing the same problem as reported here too. Some contributors to this thread have said their system sounds just fine & is performing as they think it should...that's great for them. Others are having a different experience with theirs...that's unfortunate.

As a community here, we are sharing thoughts, ideas & our experience which is why I'm here as I've learned alot from these forums. The only reason I'd be upset is if disrespectful comments are being made & if some are telling others like myself that we are expecting too much from a system with a subwoofer that is producing very little if any bass from at least the subwoofer. The rear speakers may be 4" drivers that physically produces little low end bass but the 7" subwoofer should certainly be producing an audible, reasonable amount of low end bass especially when the fader is moved to full rear, the bass EQ is moved to full & the volume is set to near the middle of the system's decibal capability. Mine does not produce the bass it should be producing & it apparently others here are also experiencing the same problem.

Anyone who would like to contribute to the thread by providing thoughts, ideas, experiences & solutions are more than welcome to & are appreciated. The thread is only meant to be helpful to those who are having the same problem and even those who say they don't have the same problem are welcome to provide their input as it is being taken into consideration for comparison. No friction between contributors is wanted or needed.

Thank you & I'm glad to know you aren't having the problem that I & others are.

I'll check. Explain what exactly "audio is muted" means?
