Our take on the Rainbow Tesla Model 3 Audio System DSP Amp, 10" Sub 2021

A complete plug-and-play audio upgrade for the Tesla Model 3, built around Rainbow's L10.1 8-channel DSP amplifier, a 10-inch dual 2 Ohm subwoofer in a sealed enclosure molded to the trunk floor, and a pair of 1-inch silk dome tweeters. Everything connects to the factory harness with plug-in connectors, so there is no cutting or splicing into Tesla wiring, and the 32-bit DSP ships with Rainbow's Model 3 tuning preloaded. The subwoofer plays up to 600Hz, covering midbass the Model 3 door speakers cannot produce. It suits owners who want a full system rather than a speaker swap, but the kit is a discontinued line sold as remaining stock, and the harness must match the car's build date rather than its model year.

About the Rainbow Tesla Model 3 Audio System DSP Amp, 10" Sub 2021

This is a complete audio system made for the Tesla Model 3. It includes an L10.1 8-channel DSP amplifier with a 32-bit DSP and Rainbow's Model 3 tuning preloaded, a 10 inch dual 2 Ohm subwoofer, and a pair of 1 inch natural silk dome tweeters. Everything connects to the factory harness with plug-in connectors, so no cutting or splicing into Tesla wiring is needed.

The amplifier takes speaker-level input from the factory system. It has eight high-level inputs and a Tesla integration module with 107 Ohm high-level input matching. Outputs are configured as 8 x 50W, 2 x 150W and 1 x 300W.

The sealed subwoofer enclosure is molded from ABS and fiber composite to fit the Model 3 trunk floor. The subwoofer plays up to 600Hz to cover midbass the factory door speakers cannot produce. The tweeters mount in the factory tweeter locations. The kit does not include door midbass drivers and is designed to work with the factory door speakers.

Questions and answers

Will this fit my Model 3?
Fit depends on the car's build date, not its model year. Rainbow made three harness versions for three wiring configurations, and Tesla's production changes do not line up with model years, so confirm your build date from the door jamb sticker or VIN before ordering.
Does it require cutting the factory wiring?
No. The harnesses use plug-in connectors to the factory harness, so there is no cutting or splicing into Tesla wiring.
What is included in the kit?
The L10.1 8-channel DSP amplifier, a 10-inch dual 2 Ohm subwoofer in a molded Model 3 enclosure, a pair of 1-inch silk dome tweeters, vehicle-specific harnesses, a Tesla high-level input integration module, mounting hardware and documentation.
How much power does the amplifier make?
The L10.1 has eight high-level inputs and outputs configured as 8 x 50W, 2 x 150W and 1 x 300W, with a 32-bit DSP carrying Rainbow's Model 3 tuning.
Why does the subwoofer play up to 600Hz?
That range lets it cover midbass the Model 3 door speakers cannot produce, filling the gap between the doors and the low end.
Is the DSP tuning already set up?
Rainbow's Model 3 tuning is preloaded, but buyers report the best results come from dialing it in further with the DSP software.
Where is the Rainbow Tesla Model 3 Audio System DSP Amp, 10" Sub 2021 cheapest?
At Audio Intensity, for $399.99, 84% off, as of our latest check.
