Sub-Woofer

I installed a new radio today...Bought a harness, hooked up all of the wires
BUT the sub woofer doesn't seem to acknowledge the new stereo...Has anybody encountered this problem?
thanks in advance

assuming that your set up runs with the stereo to an amp and then to your subwoofer:

you should have a remote line that runs from your new reciever into the amp, along with the ground and power. if its set up correctly, the amp light should be green. if theres an issue, the amp will put itself into protection mode and the light will be red.

I've had issues with my amp not even having a light on! power was getting there but no output to the sub., I checked the fuse running next to the battery terminal in the engine bay. if you have a fuse there, check that. I just took it out and put it back in and she was working like a champ.

I think he is talking about the factory sub in the console correct? Not sure how the factory amp is wired to the factory stereo, i know the harness goes right under the console, might have to find a wiring diagram and see where it gets power from and where it gets its signal from.

Since i got my jeep the factory console has not worked. The guy before me put a new kenwood stereo in it. Where do i get to the power antenna lead and connect it to the remote lead?

i'm not a genious, just have some experience from reading all the threads and installing my alpine system, but id say that the power antenna lead is going to be connected to a power antenna remote wire coming off of the reciever harness. to get to it you can either take off of the middle panel console or take out the glove compartment box and try to reach up and behind the cd player(prob. not a good idea). to remove the center console plate, you'll need a flathead or pencil to first remove the plastic panel that covers the windshield defrost vent. from there, there are two screws on the top of the center console and one behind the cigarette dash, when those three screws are removed you can just pull the center consol panel out. from there, the housing to the cd reciever can be unscrewed, pull out the reciever and you can find the correct cord off of the wire harness. its probably going to help if you have or can find the manual to your stereo just to be sure your have that remote for the power antenna.G'luck

If I read the above posts correctly, you're just looking for how to wire the subwoofer?

It's the blue wire.

It doubles as the "power antenna" power which is where the confusion is. So, unless you have a power antenna, no need to pull the console or any of that.

Just ensure the blue wire is connected to the connector and you should be good to go.

On the Alpine head units there are two blue leads. One is the remote turn on for an amp and one is the power antenna lead. Both energize when the head unit is turned on BUT, sometimes when the CD or Ipod is selected as the source, the power antenna lead de-energizes. Make sure you use the remote turn on to turn your amp on.

Nice to know that is the case with yours. I assume it's a new unit. My 2-3 year old alpine I just removed had one blue lead on the unit. So did my new JVC. I think it depends on which specific unit is purchased.

Important note, the head unit should have a wiring diagram included with in the packaging. You want to use either the combined purpose blue wire that is labeled power antenna or if there is a separate one listed specifically for the powered sub, use that.

Thanks for the info Chuck.

i have an alpine cda-7875, a little old, i think its like 01' but it retailed at $500 new and puts out the beat. anyways, the wire harness for the reciever has two blue remote turn-ons.. one might be blue/white... so stevens, your probably on the right track that different models have different wires.

so i ran into this problem today installing a couple year old panasonic

on the radio side there is a blue wire that didnt get connected to anything and on the harness side there is an orange wire and a brown wire (one says mute and the other says power antenna)

r orange wire---h
a a
d---blue wire r
i n
o brown wire---ess


so should i be connecting the blue wire to whichever one is the power antenna wire and that should solve the problem?

standard wire colors for most aftermarket radios are:

Red = Ignition
Yellow = Constant (Batt)
Black = Ground
Blue = Power Antenna
Blue/White = Amp Turn On
Orange = Illumination
Orange/White = Dimmer
Brown = Mute
Gray = Right Front +
Gray/Black = Right Front -
White = Left Front +
White/Black = Left Front -
Green = Left Rear +
Green/Black = Left Rear -
Purple = Right Rear +
Purple/Black = Right Rear -

now keep in mind not all radios use these colors.. all "name brand radios" do. some off brands use their own colors.

also good to note just bc you have extra wires doesn't mean you need them to be hooked up.. for instance Dimmer & Illumination rarily need used anymore & mute is never really used.

assuming there are 4 speakers in the vehicle you really only need 11-13 wires for it to work. 1-2 may not be needed if you don't have a factory amp & or power antenna

Jay is right on.

A bit more help: A couple years ago, had nearly the same problem. So, since I still had the connector that I cut off, I just mapped it over.

If you still have the original connector, there should only be the one or two wires to chase. Power, ground, constant and the speakers should go one to one.

Only thing you should have to find out is what "mute" is. I don't know myself.

that looks right for mine

but i still have the blue/white on the radio side which is turn amp on connected to nothing. what should i connect it to in order to have my factory sub functioning again?

the only open wires are brown (mute) and orange (illumination) open on the harness side. should i splice it into another connection to get it to work?

Maybe that "couple year old Panasonic" can't run a sub?

for all those following this intensely...

i spliced the blue/white (amp on) wire into the blue (power antenna (which the jeep does even actually have))and magically the sub works

go figure

so anyone else having this problem..^^^that is your solution

did you buy a aftermarket harness to plug into your factory harness?



if you did hook up the blue/white wire (from the above harness) which is the amp turn on for a factory amp & power antenna wire. that needs to be hooked up to the blue/white wire on the panasonic... or if the panasonic doesn't have that wire then the blue wire..

a couple things to check before you finish installing make sure radio etc all works on radio/cd everything...bazsically making sure factory amp doesn't shut off when you leave fm/am

they won't all have the blue/white.. some vehicles tie factory amp & power antenna into 1 wire...where as others will have 2. so if you go into a carwash you can still play a CD but antenna will be down.

so in your case you're correct in the way you hooked it up..i was just posting the most common aftermarket wire colors and what they do

i tried touching the blue/white wire coming out of the back of my pioneer 5100-ub head unit to the blue power antenna wire in the harness, but still nothing... and the subwoofer definitely worked before I did the install. So i guess i'm wondering where i can find the fuse that would be blown and if you guys have any other ideas. thanks a lot, much appreciated, just wanna get my stereo working the way it used to
