audio trouble

well i tried to be a technician and do some work on my 1989 honda accord lxi becasue the radio kept going on and off so i thought it was faulty conection got backtheere and undid all the woring hooked up to the plug and also was trying to run new speakers i tried to put all the wores back where tehy go and theyre all color coded like eachother but for some reason the power still wont come on. its stock everything.anyhelp will be great.

Does that radio have a security code maybe? i dunno but heres some wire info: Black is ground, yellow is constant power, red is switched power.

Did you blow a fuse by any chance? I had the same problem in my Civic once and I blew the fuse that was under the hood. You might check that out if you haven't fixed it yet.
