1992 Honda Civic Radio has only static

Check the antenna cable where it connects to the antenna. If that is good, it may be time for a new unit.

I have right now the same problem. I just pulled the fancy/shmancy radio head out of my (Honda) 1992 Acura Integra and the whole dash is now a mess. It had been professionally installed. The dome light now doesn't work, the "door open" warning lights stay on, the clock is messed up, etc.
I installed the fancy head in another car, in a 1992 Honda Civic. That works perfectly. Sounds like you need to find a professional installer to re-do your new head.
I think the dash lights and the taillights are on the same circuit/fuse.

remove the battery terminal to clear the radio, then reinstall the cable, with the key on and the radio off hold down buttons #1 and #6 while turning the radio on, this will give u the serial # of the radio and u can give it to any dealership and they can give u the 5 digit radio code, If they wont just give it to me and I can help you.

every honda i've seen with my own eyes, the radio code is under the fuse box lid. It's the fuse box under the hood on the left side of the engine compartment. If it isn't there then you probably will need to go to the dealership Good luck ...................

you will have to go to a honda dealer and see if the code is in the system

Each code is specific to the radio, you have to disable the anti-theft feature before removing the battery. The code may be listed in your owner's manual, if not, call dealer for more info

call honda they can get it for you by ur vn

call a honda dealer and thay will give you the code

I just installed a radio and speakers in my 1992 Civic LX (132323 miles). Most radios are removed by disassembling some of the dashboard components. On mine I had to remove the lower center console (where the ashtray/lighter is located) to access the rear of my old radio. There is a metal support strap back there which stabilizes the radio and provides equipment grounding. This has to be removed from the radio before you can un-install the radio. Also there may be a metal mounting sleeve around the radio, if so you must use (2) thin metal strips (or thin screwdrivers)to disengage the (2) side clips from the sleeve. You should then be able to remove your old radio.
As for wiring , I had to discard the wire harness the came from the old stereo and hard wire the new unit. I used a 12v circuit tester to find my (+) positive (typically red) and (-) negative (typically black) leads. Speaker wires are in pairs. (example: blue/white white/blue or white/white-black)

If the radio is aftermarket, they cross the circuitry of the antenna near the defroster, causing static in the antenna everytime you turn it on. Disassemble the radio and check for the wiring. Worst case scenario: they used the Positive wiring for the defogger switch and connected a wire to the radio's ACC cable.
