Make your JBL System Louder

I love my 35s and I'd put them on again in a heartbeat. But there's a handful of things I wish someone had told me before I did it, so here's the honest version for anyone planning on daily driving theirs. First, don't go as aggressive with offset as you think on the Tundra. I'm running 0 offset without quite enough lift (2in front and 1in rear), and I've had to trim, then trim again, and I probably still need to trim more. If I did it over I'd either go a little less aggressive on the offset or do a real suspension replacement like the OME MT64s to get it sitting where it needs to be. If you go the cheap route, just be ready for some rub. Now the good part. The small rim, big tire combo soaks up an absolute ton of the road when you're daily driving. It has been so much more plush since I put them on, and honestly that alone is the reason I'd do it again. Here's the big warning though: do not listen to the dealership or the tire shop about your speedometer. I got two speeding tickets in quick succession. One of them I had cruise control set to 78 in a 70 and figured I was totally fine. Officer said he had me at 88. Now I'm fighting a fix it ticket and have to go get it corrected in person. Either get your speedo recalibrated or at minimum understand that it's going to be reading pretty far off. Last point, power. I honestly didn't feel like I lost much at all. It still has plenty of get up and go and is a riot off-road. MPG is harder to say since I now know my speed and mileage readings are off. If I assume the same rate of difference I'm seeing in speed, I probably lost 3 or 4 MPG, but I also went with the Falken Wildpeak AT, which I'm sure helps a lot on that front. Bottom line, I think the pros outweigh the cons, especially if you off-road frequently. But a lot of this is preference, so go in knowing the trade-offs. Anyone else dealt with the speedo being this far off after going up in tire size? Curious if recalibrating actually got people back to accurate or if it's always a little off.

I was turned onto this by one of the guys in a Facebook group.

First, for context, I have a 2022 Limited with the JBL system. Personally, I’m not a big fan of these pre-built audio systems like JBL (or similar) because they don’t really give you a clean upgrade path later if you want to add your own amp or speakers.

The system has always sounded a little off to me. I wouldn’t say the JBL system sounds bad, but it’s kind of like taking music that’s meant to be played in 2-channel and forcing it through a 7-channel setup—you end up losing some of the detail and notes in the process.

Someone in the Facebook group suggested going into the audio settings and turning off Virtual Surround Sound. They were right—that was it. It’s basically post-processing from the JBL system to simulate surround sound, but for my personal listening preference, it sounds much better with it turned off.

Give it a shot.
