Alpine KTP-445U 4-channel Power Pack Amplifier
I recently bought this amplifier to enhance the audio performance in my 2017 WRX, and today, I’ll be unboxing it and providing you with an in-depth overview.
Unboxing Experience: Upon receiving the package, I was impressed with the contents. The amplifier comes neatly packaged with installation brackets, all the necessary cables for installation, and a manual. The compact size of the components suggests that it can easily fit behind the glove box or even behind the head unit itself.
Key Features: The Alpine KTP-445U is a 4-channel amplifier, delivering 45 watts RMS per channel. It features a built-in high-pass filter for both front and rear channels, allowing you to fine-tune your audio setup. The amplifier also offers a selector switch for two or four-channel operation, as well as the option to choose between RCA or speaker-level inputs.
Installation Overview: The installation process is made simple with the included components. The U in the model name stands for universal, indicating its compatibility with any head unit. This was crucial for me since I didn’t have an Alpine head unit. The amplifier can be powered using your existing head unit’s 12-volt supply, accessory turn-on cable, and a ground point nearby.
The input cable, equipped with RCA connectors, is perfect for head units with preamp outputs. For those without preamp outputs, like myself, you can easily cut off the connectors and use the wires directly.
Speaker connections are straightforward. By splicing the cables from your head unit to the amplifier, you can seamlessly integrate the KTP-445U into your car audio system. The unit is designed to be tucked away discreetly, making it suitable for placement behind the head unit, in the glove box, or even under the passenger seat.
My Personal Setup: While most users may opt for the glove box installation, I decided to mount the amplifier under the passenger seat for a more customized setup. In the next video, I’ll provide a detailed walkthrough of this alternative installation, catering to those who prefer a different approach.
Verdict: For those, like me, who want to preserve the functionality and stock appearance of their head unit, the KTP-445U is the ideal solution. Avoid the dilemma of choosing between a new head unit and an amplifier—keep the features you love and enhance your audio with this compact yet powerful amplifier. It’s the perfect choice for striking a balance between performance and maintaining the original look of your car’s interior.
