Many owners replace or modify the factory audio system to add modern features such as Bluetooth, USB input, improved speakers, amplifiers, or subwoofers.<br /> <br /> Audio upgrades should be planned carefully so that wiring, speaker fitment, radio mounting, power supply, grounding, and interior trim are not damaged.<br /> <br /> == Factory audio system ==<br /> <br /> Factory audio equipment may vary by model year, trim level, and options.<br /> <br /> Related topics:<br /> <br /> * [[Factory radio]]<br /> * [[Speaker locations]]<br /> * [[Subwoofer option]]<br /> * [[Interior]]<br /> * [[Electrical system]]<br /> * [[Wiring diagrams]]<br /> <br /> == Radio upgrades ==<br /> <br /> 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.<br /> <br /> Related topics:<br /> <br /> * [[Factory radio]]<br /> * [[Aftermarket radio]]<br /> * [[Bluetooth audio]]<br /> * [[Auxiliary input]]<br /> * [[Radio wiring]]<br /> * [[Dash installation kit]]<br /> <br /> == Speaker upgrades ==<br /> <br /> Speaker replacement is one of the most common Fiero audio upgrades.

Owners may also install aftermarket subwoofers or amplifiers.<br /> <br /> Because interior space is limited, amplifier and subwoofer placement should consider ventilation, wiring safety, passenger space, storage space, and serviceability.<br /> <br /> Related topics:<br /> <br /> * [[Subwoofer option]]<br /> * [[Aftermarket subwoofer]]<br /> * [[Amplifier installation]]<br /> * [[Power wiring]]<br /> * [[Ground problems]]<br /> <br /> == Wiring and electrical considerations ==<br /> <br /> Audio upgrades often require wiring changes. Poor wiring can cause noise, battery drain, blown fuses, poor sound quality, or electrical problems.<br /> <br /> Important considerations include:<br /> <br /> * Correct fused power supply<br /> * Good ground connections<br /> * Speaker polarity<br /> * Avoiding hacked factory wiring<br /> * Preventing wire chafing<br /> * Avoiding overloaded circuits<br /> * Preserving serviceability<br /> <br /> Related topics:<br /> <br /> * [[Electrical system]]<br /> * [[Fuses and relays]]<br /> * [[Ground problems]]<br /> * [[Battery drain]]<br /> * [[Wiring harness]]<br /> <br /> == Interior fitment ==<br /> <br /> Audio upgrades should not damage fragile interior trim, interfere with HVAC controls, block vents, interfere with shifter movement, or prevent access to service panels.<br /> <br /> Related topics:<br /> <br /> * [[Interior]]<br /> * [[Interior modifications]]<br /> * [[Center console]]<br /> * [[Dashboard]]<br /> * [[Interior trim]]<br /> <br /> == Common audio topics ==<br /> <br /> * [[Factory radio]]<br /> * [[Speaker replacement]]<br /> * [[Subwoofer option]]<br /> * [[Radio wiring]]<br /> * [[Bluetooth audio]]<br /> * [[Amplifier installation]]<br /> * [[Battery drain]]<br /> * [[Ground loop noise]]<br /> <br /> == See also ==<br /> <br /> * [[Interior]]<br /> * [[Interior modifications]]<br /> * [[Electrical system]]<br /> * [[Service procedures]]<br /> * [[Parts interchange]]<br /> <br /> [[Category:Fieropedia]]<br /> [[Category:Modifications]]<br /> [[Category:Interior]]<br /> [[Category:Electrical system]]</div>
