I have Accord 1994 has OEM Honda 6 CD Changer which was not working
So that I bought new Sony Xplod CDX-565MXRF 10 CD changer
Anyways I installed it and it is working fine
But the problem is every time I shut off my car the time reset and radio reset all saved channels and ask for code
I’m worried about the way I connected the power wires, I connect them to the fuse box below the dashboard

 

you need to have a constant power connected to it too. it should be to the red wire on the aftermarket headunit

 

I did that and the cd changer working fine
but the question is what would make the clock reset every time i shut off my car?

 

WHOA!

Why did you connect them to the fuse box? You probably connected them to the incorrect ones - ie ones that do not have power when the car is turned off. What's wrong with using the stock harness?

 

yea connecting them straight to the fuse panel is not a good thing...but to answer your question about why your clock would reset every time you turn the car off....with the stock harness power wire wise you have 2 wires the red one and the yellow one...the red turns the radio on when you turn the key to accessory while the yellow one is a "memory" wire and has constant power even when the car is off thus keeping the clokc and stations set

 

check your back up radio fuse under the hood too. Its a 7.5 amp fuse. They tend to blow for
some reason with an aftermarket headunit
