This product is not available yet. The Beat-Sonic Encore Sigma ENS-L202 for the 2014-2026 Lexus IS without Mark Levinson is in development and has no release date. There is no buy button on this page on purpose. We would rather tell you plainly that it is not ready than take an order we cannot fill. It will be $799, the same as the ENS-L201.
Email us your year and trim and we will contact you the moment it is available.
What it is being built to do
The Encore Sigma is a plug and play amplifier that connects directly to the factory amplifier harness. It is designed to lift the output and clarity of a factory Lexus system without replacing the head unit, the speakers, or cutting a single wire.
- Plug and play. Connects to the factory harness. No cutting, no splicing, no harness modification.
- Factory features retained. The OEM screen, navigation, steering wheel controls and chimes all keep working.
- Eight channels with independent gain so the system can be tuned rather than just made louder.
- RCA output so a subwoofer can be added later without redoing the install.
- Compact and reversible. On the IS the amplifier mounts in the trunk, and the car can be returned to stock.
Important: without Mark Levinson only
Like every Encore amplifier, the ENS-L202 is intended for Lexus IS vehicles without the Mark Levinson premium audio system. There is no Beat-Sonic solution for the modern Mark Levinson systems and none is in development yet. Mark Levinson is normally listed as a premium audio upgrade on your window sticker or Monroney label. If you are not sure which system your car has, email us before ordering anything.
How this differs from the ENA-2T3 and ENA-3T3
Two of our Encore Alpha kits also list the Lexus IS, so it is worth being clear about which car needs which part. The ENA-2T3 and ENA-3T3 fit the 2021 and newer IS without factory navigation. The Encore Sigma ENS-L202 covers a wider range: 2014 through 2026, with or without factory navigation, as long as the car does not have Mark Levinson.
On the IS, Mark Levinson was only ever sold as part of the navigation equipped system. So if your car does not have factory navigation, it does not have Mark Levinson either, and all three kits are genuine options for it. If you are not certain what your car has, send us your year and trim before you order anything.
- 2014 to 2020 IS. The Encore Sigma is the only kit that fits. The Encore Alpha kits start at 2021.
- 2021 and newer with factory navigation. Encore Sigma only, provided the car does not have Mark Levinson.
- 2021 and newer without factory navigation. All three fit. The Encore Alpha kits are the lower cost route and drive four channels. The Encore Sigma is eight channels of Class AB with independent gain, so it powers every factory speaker at once and can be tuned rather than only made louder.
- Any IS with Mark Levinson. None of the three fit, and we do not have a solution in development.
If your car is a 2021 or newer without navigation and you only want more output for the least money, the ENA-2T3 or the ENA-3T3 will do it, and the ENA-3T3 adds a subwoofer output. We would rather point you at the cheaper part than sell you an amplifier you did not need.

We filmed a development install on a 2015 Lexus IS 250, with the amplifier in the trunk on the passenger side rear corner. You can watch it in our article, Encore Sigma Amplifier for Your Lexus IS. It is a preview of work in progress, not a purchase guide.
