I had some time over the weekend to look at my system and found that the amp was the problem. My dad took it to his electrical shop, and some of the resistors were fried. The resistors were damaged to the point where the color strips were unreadable.

Does anyone have the value for resistors R807 and R808? If not, would someone be able to open up one of there amps a find the value off of the color strips?

On an explorer forum, someone had a similar problem and got each resistor to be within 5% of 56 Ohms off of color strips, but I want to make sure the resistors are the same since its a different model and year

how badly fried was it. those numbers that you threw out are just factory locations of certain components so that if someone were troubleshooting they can find it quickly. those locations and resistors may will more then likely be different on different brands unless it is the factory amps that you are referring to. You may be able to do an ohm test on the resistors value if you have access to one.

From the sound of it, they're toast. I had to drive back down to school before it was taken apart so I can't say for sure. My dad said they were fried to the extent that it was impossible to get the color strips off the resistors. The guy at the electric shop sent me the resistor numbers so i'm assuming he was unable to do any test on them. These are the call numbers out of a mach 460 amp by the way

I dont have one laying around so i cant help you out there. you may want to try contacting Visteon or going to their website as they are the ones who created the mach system for our cars

Well i contacted Visteon via email. I was very clear about all the details as far as the year, model, component, and the exact resistors i needed values for. Their response? Contact your dealership. That was the absolute worst customer service i have ever dealt with. All they had to do was pull the value from the reference number, instead they not only don't give me an answer but tell me to talk to somebody else about their own product. Now i feel like getting rid of this system on pure principle. It honestly took more work for them to tell me to ask the dealership then to just send the values. Now i get to call up a Ford dealership tomorrow and deal with that, awesome.

It's cool, no real hurry right now it just annoyed me that a company was so unhelpful with their own product. I'd tear out my other amp and get the resistance values, but i don't have a T10 here at school with me to open it up. I'll call Ford tomorrow and hopefully i'll get an answer instead of being told to ask someone else. From looking at other forums, apparently it is fairly common that these resistors get fried. When i get the values i'll post them in case someone else has the same problem

If for some stupid reason Ford won't give you the value let me know. I have a friend (not a real close friend) that's a mechanic for Ford. I could ask him if he can pull the values.

UPDATE


So last night I pull the VIN off of my car so I could email Ford, thinking this would be the fastest way. Ford emails me back saying that they won't give me the values and that I need to have my car inspected by a Ford certified mechanic. I've already had the amp inspected by far more qualified electricians and diagnosed the problem. For Ford to tell me that they won't give me a simple piece of information unless I pay them upwards of $100 to diagnose a problem i knew all along is unacceptable.

Next i decide to call my local Ford dealership so that i can actually talk to someone. The technician tells me more of the same, that they can't give me the values unless i bring the car in to them. When i asked why they couldn't just give me the values since i already have the reference numbers for the resistors, they gave me some BS about wanting to know the problem of cars under warranty. His only reason was because my car is under warranty, the problem with that however is that my car's warranty expired last year. When i told him this he backpedaled, refused to give me the values and gave me yet another number to contact.

Next I contact the so called "ford audio specialists" i was referred to. When i told them the issue and gave them the reference numbers for the resistors, what was their response? They don't have access to information that detailed. So now all in all i've contacted 4 people and have yet to receive an even remotely acceptable answer.

I'm beyond pissed right now at the customer service i've experienced. Not a single person would take the time to punch in the reference numbers and give me the values which they are capable of doing. I'm to the point right now that i want to trade in the stang for a vette. I realize it's not that big of a deal and i'm just ranting and raving but this has been completely unacceptable and unprofessional. I would not have this problem with another manufacturer

damn, im sorry to hear that bro. hopefully Sonic can get something for you. Ive got wiring schematics but just not for the internal components of the amps.

yeah, I'm hoping his friend can help me out too. Worse case scenario, I have to take out the other amp once i'm home and delay having my system fixed for a day or two. Overall, its really not that big of a deal, but as i said earlier it's just the principle of the situation that bothers me. I'm disappointed that Visteon, Ford and the local dealership were so unwilling to help.

I sent him a text and he said he's not sure if they're given that specific information but he'll look when he goes to work. If the Ford mechanics have access to that information I'll let you know.

here is another thought... I have the factory amps from my 02 Mach 460 setup in my shed. if you want to pay shipping I can send them to ya. they both work. just thinking since the two internal resistors are cooked, what else is going bad in yours... Just a thought. I will be back to my comp on Sunday night. Hit me with a PM if your interested...

I finally had time to take apart the other amp. Resistors r807 and r808 are the same. The color bands were green, blue, black, gold meaning the resistors are within 5% of 56 ohms. Hopefully I'll have the amp back tomorrow and we'll see if it was fixable afterall
