Beatsonic Sigma Amplifier for Premium Sound system

[mikessd]

Thanks fellas. Think I made my decision. Gotta have some quality sounding jams!

This Beatsonic thingamajig makes the stock stereo perfectly acceptable, almost impressive. Otherwise it's a complete tear-out and replace system. I need to up my gains from 3/4 to max and see how it sounds. Need to get under there tomorrow and make this happen.

Has anyone experienced a long beep at engine start up after installing the Beatsonic? And if so is there a fix?

Update - It’s not the amp, it’s the same sound as the rear hatch when it opens or closes. I think it’s from the FitMax+ rear camera connection. Installer working on it now.

Update to the Update - Third row seat wasn’t all the way down and locked. lol.

No. I do however notice after starting the car, the amp seems to take a split second to fire up, I can tell because the volume and clarity increase.

Hey guys, how are you all still liking the amp? Any issues? Still worth it? thx

For my ears it's a solid upgrade, but not sure if it's really worth the $800. About half that price like almost all their other factory amp upgrades go for and I'd say definitely yes.

Just to provide an update.

Got it installed today. Although the price is a bit steep, it's a night and day difference. Sound is so much cleaner and the bass definitely bumps. I appreciate quality sounding audio and would 100% recommend if you have the $$ to spare

i'll take this as good news, meaning at least the speakers are decent.
now just need to wait for a new amp for the messed up ML system.

there is a service bulletin for ML amps they have a new amp you should reach out to the dealer

GX ML SB

AMPLIFIER UPDATE

I just found out that there is a Technical Service Bulletin (TSB) for the installation of an updated amplifier for Lexus 2024-2025 vehicles, which covers NX, RX, TX, and GX. I don’t know the number but it is covered under a Lexus Service Campaign.

I had the thump on start too and fixed with removing ANC. Not sure I can tell any difference in cabin noise compared to having ANC on, so no big deal to me. Makes sense there could be issues there with the stereo trying to create artificial frequencies or whatever to offset noise it perceives.

I'm with SFLGX though in that I didn't notice a major upgrade in sound quality. I did certainly notice the volume doesn't need to be cranked way high anymore to get it at a good volume for jamming out and probably a little improvement in quality, just nothing what I would consider major at all.

How did you disable ANC?

you need a compatible OBDII adapter and 1 month of Carista or a friendly dealer.

per Lexus service manual, all dealers are supposed to "Program Lexus Personalized settings, if requested" at the 5K service free of charge.
If they forgot to mention this, you can probably point it out at your next appointment. It's not like it costs them anything.
