Encore Alpha 2 Series
4-Channel Plug-and-Play Amplifier - Toyota Vehicles
Starting at $299

The Beat-Sonic Encore Alpha 2 Series is a plug-and-play amplifier kit that dramatically improves the sound quality of your factory vehicle stereo - no cutting, no harness modifications, and no need to replace your head unit or speakers. More clarity. More bass. More detail. All from a single compact unit that installs in under two hours with the included vehicle-specific harness.

Factory head units are built to a cost. The amplifier stage inside your OEM radio is one of the first areas where manufacturers cut corners, resulting in a flat, compressed sound even through otherwise decent factory speakers. The Encore Alpha 2 solves this by strengthening and optimizing the audio signal - giving it a cleaner, more powerful signal to work with and allowing your factory system to perform closer to its true potential across all frequency ranges.

Your factory head unit, steering wheel controls, and speakers all stay in place and continue to work exactly as before. You simply get the sound your system was always capable of - finally unlocked.

45W x 4 channels - significantly more power than factory
Plug-and-play installation - vehicle-specific harness included, no cutting or splicing required
Retains factory head unit, speakers, steering wheel controls
RCA line-level inputs for optional secondary audio source
Ultra-compact design - fits behind dash or under seat
Premium hi-fi grade components - Made in Japan
Note: The Encore Alpha 2 Series does not include RCA pre-outputs for subwoofer connection. For subwoofer-ready output and wider vehicle compatibility, see the Encore Alpha 3 Series.

Your factory head unit, steering wheel controls, and speakers all stay in place and continue to work exactly as before.

4-Channel DSP Amplifier with 31-Band EQ and Time Alignment
Starting at $529
Encore X DSP 3/4 angle view Encore X DSP with harness

The Encore X DSP is Beat-Sonic's most sophisticated plug-and-play amplifier - built for the true audiophile who wants complete and precise control over every aspect of their in-car sound. On top of the 4-channel Class AB amplification, the Encore X adds a professional-grade 24-bit Digital Signal Processor running at 48kHz - the same resolution used in professional studio environments - along with a 31-band fully adjustable equalizer, time alignment, and 6-channel RCA pre-outputs for full system expansion.

What makes the Encore X truly unique is that each unit is pre-loaded with a vehicle-specific DSP audio file developed by Beat-Sonic's audio engineers in Japan. This is not a generic tune - it is precision-engineered for your exact vehicle model, taking into account the specific factory speakers, the physical distances between each speaker and your ears, the acoustic properties of your vehicle's cabin, and the signal characteristics of your factory head unit. The result is a dramatically improved sound stage and listening experience right out of the box - no manual adjustment required for most installations.

For those who want to go further, the free PC-based DSP Sound Controller Tool gives you full access to every parameter - EQ curves, time alignment values, crossover points, phase control, and more. Save up to 6 presets and switch between them as needed. This level of customization simply does not exist in any other plug-and-play factory audio upgrade.

If you are a serious enthusiast who wants accurate, reference-quality sound from your factory system - and the ability to tune every detail yourself - the Encore X is the product for you.

Encore Sigma Series
Encore Sigma
8-Channel Plug-and-Play Amplifier - Lexus Premium Audio
Starting at $799

The Encore Sigma is a dedicated 8-channel amplifier engineered specifically for Lexus vehicles equipped with premium factory sound systems. Rather than connecting to the head unit like other Encore models, the Sigma connects inline with the factory amplifier - replacing its output stage with a significantly more powerful and cleaner signal across all 8 channels simultaneously.

The result is a dramatic improvement in sound quality, dynamics, and clarity while maintaining complete factory integration. Steering wheel controls, factory display, and all OEM features remain fully operational. The RCA pre-output also enables easy powered subwoofer addition.

Active Noise Control (ANC) Note: Some Lexus vehicles use an Active Noise Control system to reduce cabin road noise. Because the Encore Sigma amplifies all audio signals including the ANC signal, this may become audible at higher gain settings. If this occurs, reduce the gain on the affected channels or disable ANC in the vehicle's settings menu. At default gain levels this is generally not an issue under normal driving conditions.
50W x 8 channels - the most powerful Encore model
Connects inline with the factory Lexus amplifier - no head unit removal needed

Frequently Asked Questions

Do I need to replace my factory head unit or speakers?
No. Every Encore amplifier is designed to work with your existing factory head unit and speakers. Your display, controls, steering wheel audio buttons, and all factory features continue to work exactly as before. The Encore simply adds power and clarity to what you already have.
Is this compatible with my factory premium audio system?
Compatibility with factory premium audio upgrades such as JBL, Harman Kardon, Bose, Bang & Olufsen, and similar systems varies by product and vehicle. If your vehicle has a factory premium audio system, check the individual product page for your specific make, model, and trim before ordering. If you are unsure which system your vehicle has, email us at info@beatsonicusa.com with your year, make, model, and trim and we will confirm compatibility.
Can I use aftermarket speakers with an Encore amplifier?
Yes. All Encore amplifiers are compatible with aftermarket speakers as long as the speaker impedance is kept within 4-8 ohms. If you are using the Encore X DSP with aftermarket speakers, note that the pre-loaded DSP audio file is tuned specifically for factory speakers. Aftermarket speakers may require the DSP settings to be retuned to account for the new speaker characteristics. You can adjust the tune yourself using the free DSP Sound Controller Tool, or have it done by a professional installer.
How long does installation take?
Most installations take 1-2 hours following the included instruction guide. No special tools are required and no wires need to be cut or spliced. The harness simply connects inline with your factory wiring. Installation videos for each product are available on the Beat-Sonic USA YouTube channel.
Is professional installation available?
Yes. Professional installation is available directly through Beat-Sonic USA at our facility in La Mirada, California. If you are not in the Southern California area, visit our Authorized Installers page to find a certified shop near you. You can also email us at info@beatsonicusa.com with your location and we will help find the nearest option.
Will installing an Encore amplifier void my factory warranty?
All Encore amplifiers use plug-and-play OEM-style connectors and are fully reversible. They do not permanently alter your vehicle's wiring. Disconnect the amplifier and your vehicle returns to its exact factory configuration with no trace of modification. We always recommend checking with your dealership if you have specific warranty concerns.
What does the DSP do in the Encore X, and do I need to tune it myself?
The Encore X ships pre-loaded with a vehicle-specific DSP audio file developed by Beat-Sonic's audio engineers in Japan, tuned for your exact factory speaker configuration and cabin acoustics. For most standard installations with factory speakers, no adjustment is needed right out of the box. If you install aftermarket speakers, or if you want to customize the sound further, the free DSP Sound Controller Tool for Windows allows full access to the 31-band equalizer, time alignment, crossover settings, and up to 6 storable presets. Advanced tuning can also be performed by a professional installer familiar with DSP systems.
Can I add a powered subwoofer?
Yes, with the Encore Alpha 3, Encore X DSP, and Encore Sigma. All three include full-range RCA pre-outputs and a remote turn-on wire specifically for subwoofer or external amplifier connection. Simply run an RCA cable from the pre-output to your powered subwoofer and connect the remote wire to the subwoofer's turn-on terminal. The Encore Alpha 2 does not include RCA pre-outputs. If subwoofer capability is important to you, we recommend the Encore Alpha 3 as the entry-level option.
Do you ship to Canada or internationally?
Yes. We ship to Canada and Mexico. For international orders outside of North America, contact us at info@beatsonicusa.com for availability and shipping information.
