4th Gen Chassis Codes: BB1 • BB2 • BB3 • BB4 | Model Years: 1992, 1993, 1994, 1995, and 1996
This page provides the complete 1992–1996 Honda Prelude radio wiring diagram for the 4th generation Prelude (chassis codes BB1, BB2, BB3, and BB4). Use this guide when installing an aftermarket head unit or troubleshooting your factory stereo in a 1992, 1993, 1994, 1995, or 1996 Honda Prelude.
The 4th generation Prelude continued the sporty coupe formula with refined styling and improved VTEC engine options. The Si VTEC trim made the Prelude one of the most driver-focused Hondas of the 1990s. The audio system used Honda’s well-documented 10-pin and 6-pin connector, making harness adapter availability excellent compared to earlier Prelude generations. Front door speakers and rear panel speakers were standard on Si trims. No factory amplifier was used on any BB-series Prelude, and aftermarket radio installation on this generation is among the most straightforward of all Prelude models.

Frequently Asked Questions
What wiring harness adapter fits a 1992–1996 Honda Prelude?
The 4th generation Prelude uses a Honda 10-pin and 6-pin radio connector. Metra 70-1721 Wire Harness Adapter and Scosche HA08B Wire Harness Adapter are the standard adapters for this application. The BB-series Prelude connector is the same as many other Honda models of the early-to-mid 1990s, making adapter availability excellent. Using a harness adapter rather than cutting the factory connector is recommended, particularly given the 4th gen Prelude’s strong enthusiast following and increasing collector value.
What size are the front door speakers in a 1992–1996 Honda Prelude?
The 4th generation Prelude uses 6 1/2″ Speakers in the front door panels on Si VTEC and higher trims. The base S trim may use a smaller speaker or dashboard-mounted configuration. Rear speakers in the BB-series Prelude are located in the rear side panels and typically use a 6×9-inch or 6.5-inch mounting location depending on the trim. Confirm the cutout dimensions in your rear panel before ordering replacement speakers.
Does the 1992–1996 Honda Prelude have an anti-theft radio code?
Yes. The 4th generation Prelude’s factory radio includes Honda’s anti-theft code system, which requires a 5-digit code to unlock the Radio after a power interruption such as a battery disconnect. The code is printed in the owner’s manual or can be retrieved from a Honda dealer using the radio’s serial number. When replacing the factory radio with an Aftermarket Head Unit, the anti-theft code system transfers only with the factory unit — an aftermarket radio has no Honda anti-theft code.
Can I install a double-DIN head unit in a 1992–1996 Honda Prelude?
The 4th generation Prelude has a single-DIN factory radio opening. Installing a Double-DIN Unit requires a custom dash kit or dashboard modification. Given the Prelude’s sleek, driver-focused interior design, most owners prefer a single-DIN head unit or a single-DIN unit with a flip-out or retractable touchscreen to maintain the original dashboard aesthetics while gaining modern connectivity.
How do I improve the audio quality in a 1992–1996 Honda Prelude without replacing the head unit?
Significant audio quality improvement in a BB-series Prelude can be achieved by replacing the factory door speakers with high-quality 6 1/2″ Component Speakers or coaxial aftermarket speakers while retaining the factory head unit. Adding sound deadening material to the inside of the front door panels reduces panel resonance and improves speaker output clarity. A Compact Powered Subwoofer connected to the factory head unit’s rear speaker outputs adds low-frequency response that the factory system lacks entirely.
