Okay so I just finished replacing a stolen car radio, but I think I messed up the wiring... When I turn off the car the radio doesn't seem to save the presets I had... it resets the whole stereo... I think it has something to do with the wiring I did... When I installed the radio there were two 12+ volt wires... One said 12+ volt constant and was yellow, and the other said 12+ volt switch and was pink... Problem was when I wired only the yellow one the car stereo wouldn't work, so I tried the pink one and that didn't work.. SO thinking I was clever I wired both to the 12+ volt and VOILA the radio turned on... Problem is I don't think that's how I was supposed to wire it... I have a '97 Honda accord Ex and I don't know if that's what I was supposed to do... :#92;
yes you wired it wrong. If you were hooking these wires up directly to the car wires, then you could have shorted something out or caused further damage to the vehicle electrical system. If you were using a wiring harness, which i highly recommend, then you need to make sure the radio has ground switched and constant power. If it doesn't have one of these three, it will NOT turn on. Now i'd have to look at exactly how you hooked up the wires to see what went wrong. like i said if you didnt use a wiring harness there is a good chance you could have blown a fuse or screwed something else up. When not using a wiring harness the wires do not match color to color.
A car stero needs 3 main wires Constant Power (Normally Yellow) for memory like radio presets Switched Power (Normally Red) Switched by the cars ignition so your radio turns on/off with your keys You can wire these two together as long as its a constant feed, youll just have to turn it off yourself... but then it will work when the ignition is off as well that way and Earth (Normally black) The rest of the wires if you pay attention you can pair them up to form the front speakers and rear speakers, it looks to me like... this is going to take sometime to get my head around ill edit it ounce ive worked it out... Either way youv got your red and black there thats positive and negative, it will turn on with those. How many speakers in the car, and are they orginal, I asume all wires have an open end? the four black and white ones sound like someones added them, and put non orginal speakers in.
the yellow wire is supposed to go to constant power. the pink wire is supposed to go to a switchable power source. usually an ACC wire.
