With many reviews saying the 14 speaker with sub system is mediocre, does anybody have plans on making adjustments to the JBL system?

Also wondering about this….

Not terribly disappointed with the JBL in our TRD Sport Premium, but there is room for improvement with the subwoofer output. I also know if it was crossed over in a different range, it would be much cleaner sounding on the lows.

My wife is against spending much money on a new car for big upgrades, but I could probably get away with a speaker upgrade or some kind of mods for less than $500.

I know it would benefit from some targeted sound deadening as well.

Honestly, I’ve been doing quite a lot of research on this to see if there’s any way to upgrade the stock JBL system. It’s mediocre at best, in my opinion. The easiest solution I’ve found is the beat sonic amplifier plug and play that attaches to the head unit behind the dash.

However, it’s $350 for that amp and you can find something a lot more powerful within that price range. Plus if you aren’t happy with the “upgrade” will have to find a replacement amp since that one will not be enough to power quality aftermarket speakers. Currently I’m thinking to replace all the speakers and the subwoofer in the respective stock locations. I want to add an amp but need something discreet, so I can hide it behind the dash or by the rear panel where the subwoofer is located. Not sure if this would cause any issues with overheating.

Has anyone had any experience with this or know how the rear panel can be taken off to get to the JBL sub?

I'm planning to install my old ten-inch subwoofer in the rear cargo area. Subwoofers significantly enhance sound quality by handling the low-frequency sounds, which lets you reduce the bass on the other speakers for a cleaner overall audio experience.

If anyone is wondering I don't know the tweeter size I assume 1"

Dash 3 1/2
Front Door 6x9
Rear Door 6 1/2
Hatch 3 1/2 I confirmed this.

Hatch speakers are on a bracket/plate will not fit a rockford fosgate P132 punch 3.5 too tall and magnet too wide.

Monkeybutt, I'm assuming you have the front door panels off. If so, can you take a look to see what might possibly be causing the rattle some folks have been reporting on here (the rattle occurs at certain bass frequencies right behind the driver side panel of the arm rest).

I have not installed the front door speakers I will assume it will possible be the speaker cable, the hatch speaker cables hang a bit and are wrapped in thin foam. Will update later on.

I will assume if anyone is getting rattle noise could possible the wires they should be wrapped in foam.

Thank you for sharing pictures! This is great! I think it's very possible that the rattle culprit may be coming from the wires I've circled in the pic below. Did you wrap those in foam yourself or was there already foam around them when you took the panel off?

(Also, side note, the front door speaker sure doesn't look like a 6x9 speaker.)

Toyota foam, I am very disappointed in the jbl speakers. I wonder if the amp is 1200w.
