Audio upgrades are modifications to the Pontiac Fiero sound system, speakers, wiring, radio, amplifier, or related interior electronics.
Audio upgrades are common because many Fieros still have aging factory radios, worn speakers, outdated wiring, or owner-installed equipment from previous decades.
Overview
The Fiero was available with different factory audio configurations, including standard radios and upgraded sound options. Many owners replace or modify the factory audio system to add modern features such as Bluetooth, USB input, improved speakers, amplifiers, or subwoofers.
Audio upgrades should be planned carefully so that wiring, speaker fitment, radio mounting, power supply, grounding, and interior trim are not damaged.
Factory audio system
Factory audio equipment may vary by model year, trim level, and options.
Related topics:
Radio upgrades
Common radio upgrades include replacing the factory radio with a modern head unit, adding Bluetooth audio, adding auxiliary input, or adapting a later GM radio.
Related topics:
Speaker upgrades
Speaker replacement is one of the most common Fiero audio upgrades. Speaker size, mounting depth, grille clearance, wiring condition, and interior trim fitment should be checked before installation.
Related topics:
Subwoofers and amplifiers
Pontiac offered a factory upgraded audio option commonly known as Performance Sound. This system included a small subwoofer enclosure mounted under the passenger side of the dashboard, a separate amplifier, upgraded speakers, and a subwoofer level slider in the overhead courtesy light assembly.
Owners may also install aftermarket subwoofers or amplifiers.
Because interior space is limited, amplifier and subwoofer placement should consider ventilation, wiring safety, passenger space, storage space, and serviceability.

- Ground problems
Wiring and electrical considerations
Audio upgrades often require wiring changes. Poor wiring can cause noise, battery drain, blown fuses, poor sound quality, or electrical problems.
Important considerations include:
- Correct fused power supply
- Good ground connections
- Speaker polarity
- Avoiding hacked factory wiring
- Preventing wire chafing
- Avoiding overloaded circuits
- Preserving serviceability
Related topics:
Interior fitment
Audio upgrades should not damage fragile interior trim, interfere with HVAC controls, block vents, interfere with shifter movement, or prevent access to service panels.
