Aftermarket radio no sound, Vehicle is a 2007 Pacifica

Customer Question
Aftermarket radio no sound ...

Aftermarket radio no sound

Mechanic's Assistant: Is this an aftermarket stereo, or did it come with the car?

Vehicle is a 2007 Pacifica aftermarket radio with that I purchased

Mechanic's Assistant: Are you fixing your Pacifica yourself? What have you tried so far?

I purchased an access interface stereo came on still no sound I tried leaving the factory radio on unplugging it and plugging in the aftermarket but after I shut it off stereo turns on still no audio

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

Main thing is I'm trying to keep the factory harness intact without cutting any wires

Ask Your Own Chrysler Question
Customer reply replied 6 months ago
Axxess CHTO-02 Wiring Interface.
Customer reply replied 6 months ago
I also purchased a regular wiring harness without a bypass or interface I don't necessarily need the end but how can I bypass it
Chrysler Mechanic: Dan, Technician replied 6 months ago

Have you tried the regular harness? From what I'm seeing on wire diagram it looks like special harness might not even be needed.

Customer reply replied 6 months ago
I tried the regular harness and it still doesn't work no audio I am being told that without the interface I will not have access to the amp unless I tap into it directly how do I tap into the amp directly using a regular harness
Chrysler Mechanic: Dan, Technician replied 6 months ago

I'm not sure what to think here, if you are sure everything is connected correctly I do not see anything other then module that comes with wire harness being problem. I'll open question back up to see if someone else has some advice. Feel free to let me know what fix was if you figure it out. Thanks.

2007 Chrysler Pacifica
VIN# *****
Customer reply replied 6 months ago
Thank you for that but how can I get the aftermarket radio to send a signal to the amp to turn on or how can I get the amp to turn on using a relay or a fuse
Chrysler Mechanic: Mechanic01, ASE Certified Technician replied 6 months ago

It should allready be on from the idpm, check power on 5 pink, 9, 1 yellow and grounds 4,11

Ask Your Own Chrysler Question
Customer reply replied 6 months ago
the amp doesn't have a turn on wire neither does the harness from the radio supposedly the radio send the signal and that's how it turns on so are you saying that I have to add a wire from the amp to the radio
Chrysler Mechanic: Mechanic01, ASE Certified Technician replied 6 months ago

im saying when you start the vehicle the computer sends a signal to turn it on not the radio

Ask Your Own Chrysler Question
Chrysler Mechanic: Mechanic01, ASE Certified Technician replied 6 months ago

you need to verify that its working by checking power and ground when vehicle is in on position with the checks I just provided

Customer reply replied 6 months ago
Will you please give me a more detailed explanation as to what I need to do in order to have the aftermarket radio turn on the amplifier thank you
Chrysler Mechanic: Mechanic01, ASE Certified Technician replied 6 months ago

im telling you how to check right now what more do you want ? go to the amp and check for power with key on are you doing that ????

Ask Your Own Chrysler Question
Chrysler Mechanic: Mechanic01, ASE Certified Technician replied 6 months ago

why are you checking purple and white? you need to check the 2 yellow and red wires and the grounds I listed above

Ask Your Own Chrysler Question
Customer reply replied 6 months ago
The two yellow and red wires do show positive power so does the pink the two ground wires show no positive power
Chrysler Mechanic: Mechanic01, ASE Certified Technician replied 6 months ago

thats because your checking them for ground, you need to switch it to ohms and see if you have any resistance

Ask Your Own Chrysler Question
Customer reply replied 6 months ago
there is resistance it shows .6
Chrysler Mechanic: Mechanic01, ASE Certified Technician replied 6 months ago

thats a ton so you have a bad ground and that needs to be repaired, the amp is getting power though and when ground is repaired it should be working, if no function then the amp is bad

Ask Your Own Chrysler Question
Customer reply replied 6 months ago
The amp works with the factory radio with a factory radio I get audio sounds great but when I plug in the aftermarket I get no sound even though the radio turns on
Chrysler Mechanic: Mechanic01, ASE Certified Technician replied 6 months ago

something must be wrong in the connections then, when you have aftermarket hooked up are you getting power at the amp?

Ask Your Own Chrysler Question
Customer reply replied 6 months ago
I've seen videos where they recommend to run a wire from the accessory to one of the relays with this particular kind of car
Chrysler Mechanic: Mechanic01, ASE Certified Technician replied 6 months ago

gotta be the head unit or wiring then

Ask Your Own Chrysler Question
Customer reply replied 6 months ago
There is nothing wrong with the wiring there's nothing wrong with the head unit have you been tried a second one something to do with this particular vehicle there's a lot of problems with no audio after you hook up a aftermarket radio

StanSayre, PA

I AM VERY GLAD THAT I TOOK A CHANCE ON YOUR PROBLEM SOLVING SKILLS. I WAS SUCCESSFUL IN REPLACING THE FUEL PUMP. MY TRUCK RUNS LIKE A CLOCK. IT RUNS LIKE THE DAY I BOUGHT IT. NO LUNGING FORWARD, THE TURBO REACTS THE SECOND I STOMP ON THE GAS, AND IT HAS A LOT MORE POWER AND EVEN SOUNDS BETTER TO ME. IT SAVED ABOUT $500.00 BY DOING THE WORK MYSELF. I GIVE YOU ALL THE CREDIT FOR YOUR DIAGNOSING THE PROBLEM, JUST FROM THE SYMPTONS I GAVE YOU OVER THE e MAIL. I WILL USE YOUR WEB SITE AGAIN AND REFER MY FRIENDS. THANKS SO MUCH FOR THE HELP.
