Product Description
Package includes:
- 1967 Firebird USA-630 Radio
- Custom Autosound UNDERCOVER II Upgrade Speaker Enclosures
This 1967 Firebird USA-630 stereo package pairs a Custom Autosound year-specific dash radio with UNDERCOVER II upgrade speaker enclosures so you can modernize sound without buying unmatched parts as separate carts. The USA-630 for 1967 Firebird applications delivers AM/FM reception, USB playback support, an auxiliary path, and BluKit-ready expansion when you want wireless streaming later. It is built to fit the factory radio opening so you keep the classic dash look while gaining clearer stations and more usable output than a worn original unit.
UNDERCOVER II upgrade speaker enclosures are the speaker half of the package, improving midrange and vocals versus leaving a new radio on worn factory cones. Matched together, the radio and speaker components give Firebird owners a straightforward path to better volume, clearer vocals, and stronger midrange for cruising, shows, and highway miles. You are not forced into cutting a modern head-unit rectangle into a valuable dash; the radio stays in the original location and the speakers stay in forms intended for classic installations.
The USA-630 is the balanced Custom Autosound choice for 1967 Firebird owners who want modern inputs without stepping up to built-in Bluetooth on day one. First-year Firebird projects often need a correct-fit USA-630 before any amp shopping.
Firebird and Trans Am shoppers in the 1967 range need a correct-looking dash radio and speakers that can keep up with road noise on second-gen and related Pontiac platforms.
Who this package is for: owners of 1967 Firebird vehicles who want a radio-plus-speaker starting point rather than building a full amplified kick-panel stack on day one. If you listen to talk radio, oldies, or streaming through a future BluKit, this combination covers everyday listening without requiring an external amplifier. If you later add an amp or additional speakers, the USA-630 still provides the dash control and source selection that classic Firebird interiors expect.
Fitment focus stays on the 1967 Firebird radio opening and Custom Autosound’s vehicle-specific USA-630 chassis for those years. Confirm your dash opening, factory air status, and speaker mounting plan before ordering if your vehicle has non-original sheet metal, a custom console, or a prior DIN conversion. The package is sold as a matched set for shoppers who want one cart, one checkout, and components that are meant to work together.
Warranty and support: Custom Autosound radios are backed by a 2-year manufacturer warranty. Questions about which USA model fits your Firebird, how UNDERCOVER II differs from the original UNDERCOVER enclosures, or whether you should choose a USA-740 package with built-in Bluetooth can be answered by calling 844-802-4499. We do not offer installation services; we supply the hardware and fitment guidance so you or your preferred shop can complete the work.
Compared with buying the radio alone, this stereo package makes the speaker decision for you and keeps branding consistent under Custom Autosound. Compared with a large competitor amplifier-and-kick-panel kit, it is a lighter, radio-first package aimed at owners who want modern sources and clearer sound while preserving the classic Firebird interior. Package contents are listed on this page; component products remain available individually if you only need one piece later for a spare or a second vehicle.
Ordering notes: select this package when you want the listed 1967 Firebird USA-630 and UNDERCOVER II together at the package price. Leave a note at checkout if your vehicle has factory air or unusual dash work so our team can double-check accessories. Descriptions on this page intentionally omit dollar amounts so the buy box stays accurate as catalog prices change. For other year bands or vehicles, use the matching stereo package listing rather than this one.
Custom Autosound has long specialized in radios that look period-correct while delivering modern features. The USA-630 sits in that role for 1967 Firebird: enough inputs and power for daily enjoyment, without forcing a smartphone dock into the ashtray. UNDERCOVER II complements that approach by improving the speaker side of the system with upgrade enclosures. Together they form a practical stereo package for owners who want better sound and a cleaner shopping experience.
After you order, keep your confirmation and the component list from this page. If you ever need a replacement enclosure, 6x9 pair, or a second radio for another project, each item remains available on its own product page. Everyday use cases include show cruises, weekend drives, and vehicles that see highway miles where wind and road noise punish weak factory speakers. The USA-630 remains a capable source unit if you later add amplification.
