Review TOYOTA Audio Equipment Radio Sedan Amplifier fits COROLLA 2020–2023

The Toyota 638-13581 audio radio amplifier is a high-performance component designed specifically for select 20-23 model year Corollas. This amplifier, manufactured by Alpine, is an excellent upgrade for those seeking to enhance the sound quality of their vehicle's audio system.

This 4-channel amplifier boasts a maximum power output of 45 watts RMS per channel at 4 ohms and 60 watts RMS per channel at 2 ohms. It employs Class AB circuitry, which offers a good balance between power efficiency and sound quality. This amplifier's power output is more than enough to drive a set of aftermarket component speakers or subwoofers, delivering clear, detailed sound and impressive bass response.

The amplifier features a compact size, measuring 12.1 inches (W) x 2.1 inches (H) x 7.2 inches (D), making it suitable for installation in tight spaces. Its top-mounted controls include a level control for each channel and a gain control, which allows users to fine-tune their system for optimal performance.

The Toyota 638-13581 amplifier also includes several protection features, such as over-current, over-voltage, and thermal protection, ensuring the safety of both the amplifier and the connected speakers. Additionally, it comes with a 1-year warranty from Alpine, providing peace of mind for customers.

Installation of this amplifier is made easier with the included wiring harness, which connects to the factory radio in select Corolla models. The amplifier can be powered using the vehicle's 12-volt battery, and its RCA outputs can be connected to the factory or aftermarket receiver.

In summary, the Toyota 638-13581 audio radio amplifier is a powerful and efficient upgrade for Corolla owners looking to elevate their vehicle's sound system. Its compact size, easy installation, and impressive power output make it an ideal choice for those seeking to enjoy high-quality audio on the go.

The Toyota 638-13581 audio radio amplifier is designed specifically for use in 20-23 model year Corollas. Here are some potential pros and cons of buying this amplifier:

1. Designed for Corollas: The amplifier is specifically engineered for the Corolla, which means it should fit seamlessly into the vehicle's existing audio system.

2. Improved Sound Quality: With a max power output of 45 watts RMS x 4 channels, this amplifier can provide a noticeable improvement in sound quality compared to the stock system.

3. Easy Installation: The amplifier comes with a wiring harness that makes installation easier and faster.

4. Energy Efficient: The amplifier has a low power consumption rating, which can help save electricity and reduce the load on the car's battery.

1. Limited Power Output: Compared to aftermarket amplifiers, the Toyota 638-13581 amplifier has a relatively low power output. This may not be sufficient for those looking for very loud or deep bass.

2. Price: The amplifier may be more expensive than some aftermarket alternatives with similar power output.

3. Limited Flexibility: The amplifier is designed specifically for the Corolla, which means it may not be as versatile as aftermarket amplifiers that can be used in a wider range of vehicles.

The Toyota 638-13581 audio radio amplifier is a good option for Corolla owners who want to improve their car's sound quality without the need for extensive customization. It offers easy installation, improved sound quality, and energy efficiency. However, it may not be suitable for those who want very loud or deep bass, and it may be more expensive than some aftermarket alternatives. Ultimately, the decision to buy this amplifier depends on individual preferences and budget constraints.

If you are a Corolla owner looking to enhance your car's sound system with minimal customization, the Toyota 638-13581 audio radio amplifier is a solid choice. However, if you want more power or flexibility, you may want to consider aftermarket alternatives. It's always a good idea to compare prices and features before making a final decision.
