First, just the "center" will improve your hearing. The telematics-compatible KSC3504 center dash replacement package instantly eliminates the muffled sound of the factory sound.

This is a dedicated package for replacing your Toyota's factory dashboard speakers with the KSC3504 speakers, which are compatible with today's telematics services. The installation panel and connector terminals are pre-installed, making the installation process extremely smooth. Upgrading from factory speakers requires minimal vehicle modification and takes only a short time. After installation, you'll experience clearer, more audible audio, with audio that tends to be drowned out with factory speakers. This is a recommended first step for those who experience muffled sound, difficulty hearing voices, or dissatisfaction with the factory sound. This product is available in four different configurations, depending on your vehicle model, so please be sure to check compatibility before purchasing.
