Is your 2004 Acura TSX’s factory audio system leaving you wanting more? You’re not alone. Many owners find the stock sound quality underwhelming. The good news is that upgrading your Acura TSX audio doesn’t have to be complicated or break the bank. This guide walks you through enhancing your sound experience while keeping a factory look.
Understanding the Limitations of the Stock System
The original Acura TSX audio system uses 8-ohm speakers, which are often lower quality. The factory amplifier, designed for these speakers, is another limiting factor. It doesn’t send a full range signal to all speakers, particularly the rear 6x9s, which receive only lower frequencies. This frequency manipulation is a workaround for the poor speaker quality, not a feature for high-fidelity sound. Simply put, the stock amp and speakers are designed to be just adequate, not exceptional.
Step-by-Step Acura TSX Audio Upgrade
To truly improve your audio, consider these steps:
Ditch the Rear 6×9 Speakers (Unless You Do This)
While 6x9s can add bass, in the Acura TSX stock setup, they’re underutilized due to the limited signal from the factory amp. Unless you plan to send a full range signal to them with an aftermarket amplifier, replacing them might not be worthwhile. Focusing on quality front and rear 6.5″ speakers can provide a more balanced and clearer sound.
Bypass the Factory Amplifier
The factory amplifier is a significant bottleneck. Removing it is crucial for a real upgrade. If you want to retain your factory head unit (receiver) for a stock appearance and steering wheel control functionality, you can still achieve excellent sound.
Utilize a Line Driver for Signal Enhancement
The factory receiver outputs a low-voltage signal (around 1 volt or less), which is insufficient for most aftermarket amplifiers. A line driver, like the Rockford Fosgate Balanced Line Driver, boosts this signal, making it compatible with aftermarket amps. You’ll need to splice into your front and rear speaker channels to connect the line driver, then use RCA cables to connect the line driver to your new amplifier.
Speaker and Amplifier Recommendations
For a balanced and cost-effective upgrade, consider replacing your front speakers with component speakers and rear speakers with coaxial speakers, both in 6.5″ size. Alpine Type-S series speakers are a popular choice known for their quality and value. To add substantial bass, a mono amplifier paired with a subwoofer like a JL Audio 12W6 can complete the system without being overly expensive.
Benefits of Upgrading Your Acura TSX Audio
Upgrading your 2004 Acura TSX audio system offers several key benefits:
- Significantly Improved Sound Quality: Experience richer, clearer, and more dynamic audio.
- Factory Look Retention: Keep your stock receiver for seamless integration and steering wheel controls.
- Cost-Effective Solution: Achieve great sound without a completely overhaul of your car’s electronics.
By following these steps, you can transform your 2004 Acura TSX’s audio system from lackluster to impressive, enjoying your favorite music on every drive.
