The Beat-Sonic ENA-3T1 is a plug-and-play amplifier kit that dramatically improves the sound quality of your factory Toyota, Scion, or Subaru stereo — and adds a dedicated RCA subwoofer output for easy bass expansion. 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.
Professional local installation available in La Mirada, Southern California. Contact us at info@beatsonicusa.com to book.
Why your factory stereo sounds underwhelming — and how the ENA-3T1 fixes it
Toyota, Scion, and Subaru factory head units are built to a cost. The amplifier stage inside your OEM radio or external amplifier is one of the first areas where manufacturers cut corners, resulting in a flat, compressed sound even through otherwise decent factory speakers. The ENA-3T1 solves this by strengthening and optimizing the audio signal before it reaches your factory amplifier — 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. And with the dedicated RCA subwoofer output, adding a powered subwoofer is as simple as running a single RCA cable.

Note on JBL models and RCA subwoofer output: The ENA-3T1's RCA subwoofer outputs are compatible with non-JBL models only. If you have a JBL-equipped vehicle and plan to add an aftermarket subwoofer via the RCA outputs, please read the FAQ below before purchasing.
Note: Select Lexus models require an extension cable for installation — see individual model notes above. Not sure if this fits your specific trim? Email info@beatsonicusa.com with your year, model, trim, and audio system before purchasing.

Frequently asked questions
Will I need to replace my factory speakers or head unit?
No. The ENA-3T1 works with your existing factory head unit and speakers. You keep everything in place — the amp simply adds power and clarity to what you already have.
Is this compatible with aftermarket head units?
The ENA-3T1 works with aftermarket head units as long as the factory head unit retains the factory connectors that our ENA-3T1 plug and play harness connects to.
Is this compatible with JBL?
Compatibility with JBL systems varies by model — check the compatibility list carefully. If you are unsure, email info@beatsonicusa.com with your year, model, trim, and audio system before purchasing.
Can I add a powered subwoofer using the RCA outputs on a JBL-equipped model?
No. The ENA-3T1's RCA subwoofer outputs are compatible with non-JBL models only. On JBL-equipped vehicles, there is a known issue where the radio's volume control does not control the aftermarket subwoofer connected via the RCA outputs — meaning if the vehicle volume is set to 0, the subwoofer will still play. We are currently working on a solution for this. In the meantime, the workaround is to use a subwoofer with a separate bass volume control knob and adjust the subwoofer level independently from the radio volume. If you do not plan on adding an aftermarket subwoofer via the RCA outputs, this issue does not affect you and the ENA-3T1 will otherwise function normally on compatible JBL models.
Can I add a powered subwoofer with this amp?
Yes. The ENA-3T1 includes a dedicated RCA subwoofer output specifically for easy subwoofer expansion. Simply run an RCA cable from the sub output to your powered subwoofer.
Some Lexus models say they require an extension cable — is that included?
The extension cable is included if you selected the appropriate Lexus vehicle on the drop down menu. The models that require it are noted in the compatibility list above. Email info@beatsonicusa.com if you have questions about your specific vehicle.
Can I use aftermarket speakers with this amp?
Yes. If using new aftermarket speakers, keep the impedance at 4Ω–8Ω.
Will my steering wheel controls still work?
Yes. All factory features including steering wheel controls and your factory display continue to work normally.
What is the RMS output vs. peak output?
The 50W x 4ch rating is peak output. RMS is the continuous power output your amp delivers — peak is during short bursts. This is standard across the amplifier industry.
How long does installation take?
Most installs take about 2 hours following our YouTube video guide. Professional installation is available in Southern California or through our authorized installer network worldwide.
Does this ship to Canada or internationally?
Yes. We ship to Canada and Mexico.
