<br />
The system is commonly known by Fiero owners as the factory subwoofer option. It added a small subwoofer system to the Fiero interior, along with related controls and audio components.<br />
<br />
== Overview ==<br />
<br />
Performance Sound was Pontiac's upgraded factory audio option for the Fiero. It included a small subwoofer enclosure mounted under the passenger side of the dashboard and a separate subwoofer level control mounted in the overhead console area.<br />
<br />
The option is often discussed during audio repairs, interior restoration, factory-option identification, and RPO-code research.<br />
<br />
== Components ==<br />
<br />
The Performance Sound system may include:<br />
<br />
* Subwoofer speaker<br />
* Subwoofer enclosure<br />
* Amplifier<br />
* Overhead subwoofer level slider<br />
* Related wiring<br />
* Factory radio integration<br />
* Upgraded speaker equipment, depending on model year and configuration<br />
<br />
== Subwoofer location ==<br />
<br />
The factory subwoofer enclosure is mounted under the passenger side of the dashboard.<br />
<br />
Because the system is built into the interior, missing or damaged parts may not be immediately obvious unless the dash area, overhead console area, wiring, and speaker locations are inspected.<br />
<br />
== Overhead control ==<br />
<br />
The system uses a subwoofer level slider mounted in the overhead console/courtesy light area.<br />
<br />
This control allows the driver to adjust the subwoofer level separately from the main radio volume.<br />
<br />
== RPO code ==<br />
<br />
Performance Sound is associated with a factory RPO code.<br />

* [[Service parts identification label]]<br />
<br />
== Common issues ==<br />
<br />
Common Performance Sound issues may include:<br />
<br />
* Missing subwoofer enclosure<br />
* Failed subwoofer speaker<br />
* Failed amplifier<br />
* Broken or missing overhead slider<br />
* Damaged wiring<br />
* Poor sound quality<br />
* Previous-owner audio modifications<br />
* Factory system removed during aftermarket radio installation<br />
<br />
== Restoration and repair ==<br />
<br />
Restoring the Performance Sound system may involve locating missing parts, repairing wiring, replacing the subwoofer speaker, repairing or replacing the amplifier, and reconnecting the factory control.<br />
<br />
Because many Fieros have had aftermarket audio work performed, wiring should be inspected carefully before assuming the factory system is intact.<br />

<br />
== Identification ==<br />
<br />
A Fiero may have Performance Sound if it has the overhead subwoofer slider and the factory subwoofer enclosure under the passenger side of the dashboard.<br />
<br />
The RPO label can also help identify whether the car was originally equipped with the option.<br />
<br />
== Notes ==<br />
<br />
Performance Sound should be distinguished from aftermarket subwoofer installations. The factory system used Pontiac-installed components and integrated with the original interior layout.<br />
<br />
When documenting this option, include model-year applicability, RPO code information, component locations, wiring notes, and photos where possible.<br />
