Wiring Head Unit From scratch

[hondarider380]

I would like to know how to wire a CD player from scratch I have a 91 Honda Civic Hatchback and it came with no audio wires at all to hook to a head unit. I looked in the car manual box and it doesn't even show a radio in the dash it shows everything besides it and in the picture it shows a blank space where if there was a radio where it would go. I was looking at my CD player that I picked up from my uncle and all this seems easy to hook up, Power goes to battery, ground goes to frame, speakers go to speakers, But what does the memory B+ hook up to ? but can any one tell me how to hook up all these wires besides the speaker wires cuz they are easy I just want to make sure I do it 100% right. Thanks guys.

Power doesn't go to the battery. It goes to a switched 12v source. This means it's off when the car is off and on when the car is on. That is the red wire. The memory b+ is what goes to the battery(it should be yellow). Black goes to ground. All the rest are speaker wires except for like dimmer and maybe power antenna and remote turn on.

Oh ok I get it B+ is prolly Battery positive.. Do I just hook power to 12v fuse?

look at the fuse box there should be a fuse for the radio or at least a slot.

Ok so I wired everything for my first time wiring a head unit I feel I did a Good job ive wired my system a couple times... ok so first thing is I just connected the Memory B+ straight in my hooking it to a fused, I had to use the cigarette lighter relay because the radio wasnt switched and would be on all the time so when I put my system in this car it might sound weird but I hooked the REMOTE wire to my amp straight to my head lights which when I turn my headlights on it will then power my system.. is this a bad thing ? also hooking straight to a fuse could this cause problems? also should I not have the REMOTE wire to the headlights?

Remote wire from the radio, to the headlights? Lulz.

It should go like this..

Black To ground.

Red to radio fuse.

Yellow to Battery Positive.

Remote to your amp's remote turn-on.

Nothing should be hooked to your headlights.

There may also be a blue single wire off the HU that would be the amp turn on lead it's a switched 12+
