Frequently Asked Questions
What is the factory radio connector in a 1992–1995 Honda Civic EG?
The EG Civic uses Honda’s standardized 10-pin and 6-pin radio connector, which became common across Honda’s lineup during the early 1990s. Metra 70-1721 and Scosche HA08B are the standard adapters for this application. The EG Civic’s connector is the same as many other Honda models of this era, making aftermarket adapter availability excellent.
Does the 1992–1995 Honda Civic Del Sol have the same radio wiring as the EG sedan?
The Del Sol (also called CRX del Sol in some markets) shares the same basic radio connector as the EG Civic, so the same harness adapter applies. However, the Del Sol’s speaker locations differ from the sedan and hatchback — the Del Sol uses a different door speaker configuration and has no rear seat, eliminating rear speaker locations. Speaker wiring present in the factory harness reflects this unique two-seat layout.
What speaker size does the 1992–1995 Honda Civic EG use in the front doors?
The EG Civic uses 6 1/2″ Speakers in the front door panels on DX, LX, and EX trims. EX trims may include a factory tweeter location in the A-pillar or door panel. The factory speaker depth clearance in the EG door is adequate for most standard-depth aftermarket 6 1/2″ Speakers without spacer rings.
Is there an amplifier in the 1992–1995 Honda Civic EX?
No. The EG Civic EX does not include a factory amplifier. All speaker outputs run directly from the head unit. The EX trim added an upgraded factory head unit and additional speaker locations compared to the DX, but the signal path remained amplifier-free. This means a clean, straightforward aftermarket head unit swap with no amplifier bypass required.
How do I get better bass from the stock speaker locations in a 1992–1995 Honda Civic?
The EG Civic’s factory speaker locations are limited in size and placement for producing meaningful bass. The most effective upgrade is installing a Compact Powered Subwoofer in the hatch area or under a seat, powered from the aftermarket head unit’s subwoofer preamp output. Full-range speaker upgrades in the door locations will improve midrange and treble but will not significantly improve bass response without a subwoofer.
