Why your factory stereo sounds underwhelming - and how the ENA-3H3 fixes it
Honda 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-3H3 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.

Frequently asked questions
Will I need to replace my factory speakers or head unit?
No. The ENA-3H3 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-3H3 works with aftermarket head units as long as the factory head unit retains the factory connectors that our ENA-3H3 plug and play harness connects to.
Is this compatible with Bose factory systems?
No. The ENA-3H3 is only compatible with non-Bose models. If your Honda is equipped with a factory Bose audio system, this kit will not work. Compatibility also depends on your specific display size and speaker count - check the compatibility list carefully before purchasing.
I'm experiencing feedback or noise from my speakers while driving - what should I do?
If you notice feedback on your speakers, particularly at higher speeds, this is likely caused by your vehicle's Active Noise Control (ANC) system. Disconnecting the ANC may resolve the issue. Check your vehicle's owners manual to see how to disconnect the ANC.
Can I add a powered subwoofer with this amp?
Yes. The ENA-3H3 includes a dedicated RCA subwoofer output specifically for easy subwoofer expansion. Simply run an RCA cable from the sub output to your powered subwoofer.
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.
