What are the alpine car stereo wiring color codes for model 7284 stereo?

The yellow is unswitched 12V (battery)

red is switched 12V (ignition)

black is ground

the rest should be speakers. usually there's 2 of each color, one solid and one with a black line on it. so if you have one solid purple and one purple w.black line, solid is pos. for a single speaker and black line is neg for that speaker. So say you have 4 colors that one of each has a black line on. it doesnt really matter which is which, it will just mess with your stereo (i mean left/right, not your physical stereo)

Hooking up an aftermarket stereo is usually trial & error. keep trying till you get it right, just make sure you get power to only yellow & red.

Sorry if this is confusing. Check installdr.com to see if they have a guide for your car.

What model it it?

if not, have a look at installdr.com

Hi,

I have a 7256 Alpine car stereo without a wiring diagram. This is from around 1987. What should the colored wires be connected to? The colors are: red, black,dark blue, purple, gray, yellow white, green, and brown. A second red wire is labeled "for interface 2007."

Thanks
