so i put in my alpine headunit and it doesnt save memory. my stock head unit did it as well, i had to keep putting in the theft code everytime i started the car, if that helps? i cant have presets or save my sound settings nothing, did i miss a wire, their is a wire marked memory but my buddy said it doesnt need to be hooked up??????? if id does were would i be hooking it up to??? i also read about a dimmer wire so it would dim with the lights on and off type thing were is that supposed to be hooked up im wondering as well..ok im gonna shut up now, thanks for the help its greatly appreciated!!!!!!

Your buddy is a moron and needs to stay away from anything to do with cars.

Yes that wire needs to be hooked up. It gets hooked up to the constant power wire in the radio harness.

Are you using a harness adapter plug? If so, why did you not just match up the colors from the deck to the plug?

 

he did it all for me so i dont know what he did, i kinda figured that so what color is the wire, and yes its an adapter plug and all. haha i also noticed he hooked up the speakers backwards, because when i fade it to the front or the back its backwards haha

Alright. Here's what you do. Pull the radio out of the dash. Unplug the harness adapter plug and look at the colors of the wires. Make sure white goes to white, white/black goes to white black, etc... If there are any mismatched colors, disconnect them and reconnect to their color match. If there are any unused wires in either harness, cap them off.

Then, reinstall the deck and I bet everything works, provided that your "buddy"s handywork hasn't blown a fuse somewhere.

Have a beer, and kick that guy in the sack once for me.

 

i tried that and their was 2 red wires and a yellow wire that were together and when i took them apart and put the yellow on with the yellow the headunit wouldnt turn on.....any ideas..i was thinking about just taking the memory wire and splicing it to the constant wire in the cigarette lighter if their is one, what color would it be?

 

Check the radio fuse under the dash and the radio fuse under the hood.

 

sounds like your buddy should keep his hands outof a car. if you still havent fixed it or your buddy fried something kick his *** and keep his hands off of your car

its a cda 9847, also when i got the car the fuze under the hood was blown for memory and i replaced it and now its blown again, any ideas????

 

sounds like you have something grounding out, pull out your head unit and see if any of the wires are touching each other or any bare wires

 

ok being i used to install car audio for the last 6 or so years and have seen this problem several times, here is my input,, ok the only 3 wires that must have 12v power on your cd player, are.... the ground(black), red(12v turn on when ignition key is turned) and yellow( memory, recieves constant 12v power all day long), the reason as you already know you could not keep memory is he had both the red and yellow running to the switched 12v source. an easy, not pretty fix is, pull the radio, get a multimeter and search for a wire back there with a constant 12v power when car is off, thats after you check and make sure fuse's are good, if you simply cannot find a 12v constant wire, the ugly thing to do, is simply run a new wire under the dash to the fuse box, find a fuse thats always hot even with car off, pull fuse, wrap wire around it, and there you go, you have memory, its never pretty but it will get the job done.

Don't forget you also need a good ground, the oem one can't carry the load so you need to "beef it up" using a metal back support off the HU to the metal oem back support brace will give you all the ground you need, if you do not have a metal back support to metal back support brace, run a 12ga wire from the HU's chassis to the cars chassis. 94

 

what size fuse are you replacing under the hood. if its the backup fuse its a 7.5 amp fuse, your new deck has a 10 or a 15 amp fuse. normally this is a big no no but you will need to put in the same size fuse as the new radio.

 

^^^^^ that is considering you check out things first and make certain their isnt a short in that circuit.

Under no conditions do you replace an existing fuse with a bigger one EVER the fuse that is used is there to protect the max current that wiring off the fuse can handle, installing a bigger fuse will allow more current to flow through the wiring and can cause overheating, [and burning] of the wiring.
There is also the problem of how much current a wire can carry, even if you install a bigger fuse does not mean the load, [HU] will get the current it needs as it will only be turned to heat because the wire is not thick enough. 94

 

if the memory wire in my civic cant handle the extra 2.5 amps of current and i have to upgrade the wire for my headunit, then im going to douse the car with laquer thinner, light it and shoot my self in the head.

 

Well go hard, it is the most common problem we fix in the shop for self installed systems that come to us with a problem.

And if you are prepared to torch you car instead of doing the job right, give it to me instead.

Keep this in mind, the HU itself will need the 10A the oem one only used it as memory, probably less then .5A the other 7A is for the other things on that circuit. so its not an extra 2.5A but more like an extra 9.5A. 94

 

well we can argue all day, but ive put decks in several base model civics that dont even have that fuse in the box, and come with a block off plate. everything else works without that fuse in there so i dont know of any other accessories running off of that particular circuit. thus my reasoning for it being ok for extra 2.5 amps.<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by 5THGENSI &raquo;</TD></TR><TR><TD CLASS="quote"> normally this is a big no no </TD></TR></TABLE> idunno? any way hows the recovery going?

 

well the story is i have memory now the kid that installed it wired it wrong. i also put in a fuse and it hasnt blown yet so maybe im all set thanks for the help

 

ya make sure the battery power wire and battery constant wire arnt backwards..

I have been installing for 30 + years and I have yet run into a Honda/Acura 82 up that does not come with a memory wire for the HU, and although not always a 7.5A in engine bay fuse box, and not always for anything else, EG: 96 true 98 Civic the 7.5A fuse, [fuse 47 in under hood fuse box] is memory for the OEM HU and a constant power for the A/C switch, and even if you do not have A/C the fuse is still needed for the oem HU. In a g3 Integra there is also a 7.5A fuse, [fuse 47 in under hood fuse box] for OEM radio memory and a constant power for the ECM/ECU on a g2 Integra the memory fuse is fuse 14 a 15A in under dash fuse box, it is also the fuse for the dome, map and trunk/hatch lights.

So no we can't argue all day, there is no good reason to replace an OEM fuse with a bigger one, and just because you say you have installed decks in "several base model civics" and that fuse is not there and there is a "block off plate" makes me ask the question, what Civics. 94
