Installed Pioneer DEH-P7400MP yesturday

[twizyours]

Well yesturday I installed my Pioneer DEH-P7400MP and all I can say is wow. It was alot better then I was expecting plays real clear and loud except the the ES's stock speakers cant really handle the power when raised. I am really happy I decided to get it now, was going to wait to later but when I saw it on sale at cardomain.com for $240.00 I had to purchase and it was deffinately worth it. I went to a junk yard and not expecting to find any , I was lucky and they had a 2000 in the yard and it still had the the little compartment under the stereo in their. I got it for $10.00. I will say that if you want factory looking it is probally the best thing to go with, although I havent seen any of the installation kits yet. Basically the din sized compartment is like a cartridge and slides in and snaps in the back(looks like the same as MP3). 1st MP3 in NH yousay Pin 12: Green / Black - n/a but I found that to be the Illumination(just noting). I will say that 1st MP3 in NH your wiring directions were very good. I used my Multi and checked to the ground power illu and so on but followed the speaker wires and that saved alot of time and were accurate. Didnt check for dimmer though. Thought I would also note that the the power wires are same colour shceme as 89 probes, dont know if it is a ford or Mazda wiring or a general wiring colour scheme, just thought I would note that. Also I used for the first time twisting reusable connectors and found them to be alot quicker and tight connection. Wanted to solder wires but didnt have time and figured later on I will be installing amps and other stuff and would probally do it then but with these connectors I was satisfied with the connection and how tight it was and think I will leave those (also did usuall electrical tape security on each individual wire and then all wires together for factory harness look and extra tightning security).

What did you test the wires with?
How do you know it is illumination?

I didn't test the wires myself, I only rounded up the info from various places.

What did you test the wires with?

DMM

How do you know it is illumination?

Well when i turned the lights on 12V was there, when lights were turned off 12V was gone, that is how I always check for illumination. Works because when radio is off and lights are on the buttons illuminate and when the lights are off the buttons arent illuminated.

Just wanted to be sure before updating the wiring list, Thanks!

Hey maybe you could give me some help. About 30 minutes ago the sound just shut off. I have been driving all day today and yesturday and no problems, all of a sudden 30 minutes ago just the sound shut off. Well once I got home I turned the car off and the sound all the way up and I could hear it in the back vaguelly. Well I pulled out the head unit pulled out all the speaker wires and connected a clarion 6 1/2 to each and only one speaker connection I could vaguelly hear. Put the DMM to the speaker wires and only one Speaker connection is giving about 5V and 3ma. What do any of yall think is the problem. I tried calling Pioneer but they said I had to wait 10 minutes so thought I would post hear. I dont think I could have did anything wrong. I have installed plenty of radios and have never had a problem. Do you think I did something wrong. It was workinf fine at first. Then all of a sudden no sound.

Well got in contact with sound domain and pioneer and they both think it is the amplifier in the HU. Well So far SoundDomain seems to be very cooperative. I told them everything I did like I posted before and they said sounds like amplifier, send it in for exchange and send the copy of shipping fees and I will be reimbursed. Well see what happens, but so far sounddomain has great customer service. I think it is the amplifier in the head unit as well but I think I kind of really blame UPS. I used to work their and when I found out it was being shipped through them I said oh s***. Well hopefully I will get a new one soon and all will be resolved. I really loved the HU why it was working.

Make sure to disconnect all wires except power ground and accesory power when you test each speaker. only connect one speaker at a time. ALso try to find the rest button on the radio or just leave power disconnected for 10 minutes.

Well it was sitting all night disconnected getting ready to ship after reading this I decided to try one more time before going to fedex. Well went to car connected power, acc ground, and checked speakers again same thing. Thanks for the help but pioneer, sound domain think it is the amp and I will say the same. I have installed to many radios to have screwed wiring up, but still left it open just incase but its not me.

Thanks for help I am going to ship it now.

I not saying its the wiring or the unit just want to help make sure everything else was in perfect order before you got a new one andfound the same issue.

Hey I deffinetly agree with you and would say the same thing, part of the reason why I went out again and checked after reading the post. Thanks for the help. After reading my last post hope it didnt seam like I wasnt, I just worked 12 hours and then rechecked and then had to go to ship it because it still wasnt working and then still had to go to work tonight. also upset because it wasnt working, really liked it the 18 hours it worked fine lol. I deffinatley though appreciated you responding quickly because I really did like it and wanted another one rite away and didnt want to wait on getting it back and then recieving it(their all the way on the west coast), but if it would have worked then I might have just been getting another and have the same problems or I might have just been doing something wrong and been inconveincing myself. I deffinatly know now it is the head unit and shipped it. Thanks again for you help.
