The 09 Chevy Cruze may not boast a top-of-the-line sound system, but enhancing it is surprisingly straightforward. This article details a simple approach to adding an amplifier and subwoofer to a base model 09 Chevy Cruze with the factory non-MyLink stereo system, focusing on a practical solution for short-term ownership.
Enhancing the Factory Stereo
The factory sound system in this particular 09 Chevy Cruze, a 1.6 DOHC non-turbo model, includes rear door speakers but lacks rear deck speakers. This suggests the absence of the premium Pioneer system with its dedicated amplifier. Rather than replacing the entire head unit, a cost-effective approach was chosen: adding an amplifier and subwoofer by splicing into the existing wiring harness with a line out RCA converter. This setup prioritizes bass enhancement over features like integrated Bluetooth, which can be easily addressed with a Bluetooth adapter for the auxiliary port.
Aftermarket Stereo Considerations for 09 Chevy Cruze
While an aftermarket stereo was considered, research suggests that retaining the factory top screen functionality with a base model 09 Chevy Cruze is possible. Using a GMOS-044 interface module might allow for aftermarket stereo integration while preserving the existing display. It’s believed that neither the GMOS-045 nor the PAC interface is required for this specific configuration, and the ASWC steering wheel control adapter might be optional as system time and settings could potentially be adjusted by holding the disconnect button on the steering wheel controls. However, this hasn’t been verified through practical application.
Amplifier Remote Wire Connection in a 09 Chevy Cruze
A key consideration when installing an amplifier is identifying the appropriate remote turn-on wire. While a standard ignition wire is typically used, the 09 Chevy Cruze wiring diagram presents a potential alternative: the “integrated center stack wakeup signal.” Whether this signal is suitable for triggering the amplifier remains unclear. If this option proves unreliable, the cigarette lighter circuit could serve as a backup.
Practical Approach for Short-Term Upgrade
Given the short-term ownership plan (two years), this minimalist approach offers a balance between cost and audio improvement. The focus is on enhancing the bass response without undertaking a complete stereo overhaul. Future updates will be provided if any unexpected issues arise during installation.
