Why your factory stereo sounds underwhelming - and how the ENA-3T3 fixes it 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 ENA-3T3 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. Key features Plug-and-play installation - no special tools, no harness modifications, no cutting 50W x 4-channel output - significantly more power than factory head unit amplification Dedicated RCA subwoofer output - easily add a powered subwoofer without additional wiring complexity. On JBL-equipped Toyota vehicles, pair it with the ACS-T02 Powered Subwoofer Controller to keep subwoofer volume tied to the factory radio. Note: on Lexus vehicles, the factory radio volume does not sync to the RCA subwoofer output and the ACS-T02 is not compatible - a separate volume control solution will be required for subwoofer use on Lexus High-quality FET op-amp input stage - reproduces fine musical detail including voice tone and breath at high resolution Ultra-compact design - flexible installation location, fits easily behind the dash Premium acoustic components - low-impedance capacitors and 70μ extra copper thickness for improved frequency response across low, mid, and high ranges Retains factory head unit - your display, controls, CarPlay, and all factory features continue to work normally Compatible with aftermarket speakers - keep impedance at 4Ω-8Ω when using aftermarket speakers Made in Japan Specifications Maximum output 50W x 4ch (4Ω) Compatible impedance 4-8Ω Input sensitivity 0.5-5V Frequency response 15-80kHz (+0, -1dB) Total harmonic distortion 0.01% (1kHz / 4Ω) Power supply DC12V (minus ground), DC11V-15V range Current consumption 0.2A (no signal) Fuse 15A Audio output AUX level (RCA) + speaker level (high-level input) Dimensions 96mm (W) x 40mm (D) x 113.5mm (H) Weight 420g Compatible vehicles The ENA-3T3 is compatible with the following Toyota and Lexus models: Show all compatible vehicles ▼ Make Model Years Notes Toyota 4Runner 2020-2026 Toyota Avalon 2019-2022 Toyota bZ4X / bZ 2022-2026 Toyota Camry 2018-2026 Toyota Corolla & Corolla Cross 2020-2026 Toyota Corolla Hatchback / GR Corolla 2019-2026 Toyota Crown 2023-2026 Toyota Grand Highlander 2024-2026 Toyota Highlander 2020-2023 Not compatible with JBL + 12.3-inch screen Toyota Highlander 2024-2026 Toyota Land Cruiser 2024-2027 Toyota Mirai 2023-2025 Toyota Prius 2020-2026 Toyota RAV4 2019-2025 Toyota RAV4 2026 Without JBL only Toyota Sequoia 2020-2026 Toyota Sienna 2018-2026 Toyota Tacoma 2020-2026 Toyota Tundra 2020-2026 Toyota Venza 2021-2024 Not compatible with JBL + 12.3-inch screen Subaru Solterra 2026 Subaru Trailseeker 2026 Subaru Uncharted 2026 Lexus ES 2019-2025 8-inch display only - not compatible with 12.3-inch display Lexus IS 2021-2026 Without navigation only Lexus NX 2018-2021 Without navigation only Lexus RC 2018-2025 Without navigation only Lexus RX 2020-2026 Without navigation only Lexus UX 2019-2026 6-speaker models only - not compatible with 10-speaker Premium Sound Not sure if this fits your specific trim?

Frequently asked questions Will I need to replace my factory speakers or head unit?No. The ENA-3T3 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-3T3 works with aftermarket head units as long as the factory harness connectors that the ENA-3T3 plug-and-play harness connects to remain in place. Is this compatible with JBL factory systems?Compatibility with JBL systems varies by model. Some JBL models are compatible and some are not - check the compatibility list carefully before ordering. On JBL-equipped Toyota vehicles, the factory radio volume does not control an aftermarket subwoofer connected via the ENA-3T3's RCA outputs - the subwoofer keeps playing even at volume 0. The fix is our ACS-T02 Powered Subwoofer Controller, which restores volume sync on JBL Toyota vehicles. Your factory-installed subwoofer is not affected either way. If you are unsure, email [email protected] with your year, model, trim, and whether you have JBL before purchasing. Can I add a powered subwoofer with this amp?Yes. The ENA-3T3 includes a dedicated RCA subwoofer output for easy subwoofer expansion. Simply run an RCA cable from the sub output to your powered subwoofer.Toyota non-JBL vehicles: volume syncs normally with the factory radio.Toyota JBL vehicles: add the ACS-T02 Powered Subwoofer Controller to restore factory volume control over the subwoofer.Lexus vehicles: the factory radio volume does not sync to the RCA subwoofer output on Lexus models, and the ACS-T02 is not compatible with Lexus. A separate subwoofer volume control solution will be required. What is the ACS-T02 and do I need it?The ACS-T02 is our Powered Subwoofer Controller for Toyota JBL systems only. You need it if your Toyota has the factory JBL system AND you are connecting an aftermarket powered subwoofer to the ENA-3T3's RCA outputs. Without it, the subwoofer will not respond to the factory volume control on JBL Toyota vehicles. The ACS-T02 is not compatible with Lexus vehicles. If you do not have JBL, or you are not adding a subwoofer, you do not need it. Can I use aftermarket speakers with this amp?Yes. If using aftermarket speakers, keep impedance at 4Ω-8Ω. Will my steering wheel controls and CarPlay still work?Yes. All factory features including steering wheel controls, CarPlay, Android Auto, 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.
