No Bass in JBL Rear Subwoofer & Rear Door Speakers

[MomtyZooma]

Toyota wants $120 for diagnostics. For a car under warranty nope. Going to dealer to see if they have a comparable system to compare with my salesman.

Thanks for reporting this. How old is your 4Runner?

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

dont need to, i can tell the sub is acting just like our 2018 tundra

So is that just how it’s suppose to be? I mean sounds fine for me sitting in front anyhow. I can tell there is a night and day difference in our 25 Camry jbl vs the 4Runners

If you look up the price of the head unit on the Toyota Parts website you will be amazed . $14,000+
For that amount of money , it should sound better than my Home Theater !

That right there confirms it for me. There's definitely something wrong with the sound system. Thank you very much for posting those clips!

also forgot to mention the sub in the tundra is behind the passenger rear seat bolted to the rear wall unlike the 4runner out in the open.

That means the subwoofer in the 4Runner should be bumpin'!
