i have a pretty new kenwood cd player. i had alot of trouble in the begining with it over heating because i used the wiring from my pioneer. so i tracked down the stock wires and i know i wired them up right. it only over heated like twice and it worked great after that. i used it for like 4 or 5 months with no problems what so ever and it sounded great and everything. well yesterday i was going around a curve pretty fast and i was listening to a cd and it skipped a couple times and then just went out comepletely. all the power works fine and everything but there is no sound what so ever. i thought it might be a loose connection but i didnt find any at all. im going to take out my whole radio pod today to try to find a bad wire or connection someplace i cant see. can somebody tell me what would cause this? thanks alot

 

Internal short. If it is under warrenty, send back to kenwood for an inspection.

 

it is under warranty but i got it off of ebay so i dont think it counts. how much would it cost to fix it at an electronics store? i thought kenwoods are supposed to be good quality? this is the most trouble i have ever had out of a cd player! its terrible

 

also, this is how its wired up,

green- rear speaker
green with black- rear ground

pruple- light blue
purple with black- dark blue

white- grey
white with black- grey with black

grey- green
grey with black- light green or green with black, cant really see it too well.

is this wired up right or is it an error on my part? thanks alot

 

are you using a wire harness or is the deck wired directly to the car's wiring. if you have an after market harness, all of the colors should match up.

 

no, its wired directly into the deck. the previous owner of my car but out the stock harness and then wired all the grounds together. so i fixed all that and i have it wired right into the harness that goes into the back of the deck

 

heres what it should be or somewhere close to it:

yellow- orange
red- yellow
black- black
white- tan
white w/black- grey
grey- light green
grey w/black- dark green
green- brown
green w/black- yellow
purple- dark blue
purple w/black- light blue

the first colors are from your deck, the second should be from your car.

 

ok, so i think the purple wires are backwards. i have the purple with light blue, and the purple with black wit dark blue. would this cause my problem? why would it have worked soo well for soo long and then just not work now if that is the problem?

 

if those are the only 2 messed up, then wiring is probably not the problem. that would not cause it to crap out on you, just cause the speaker to sound off from the rest. i would check all of your stuff and make sure it is right.

 

i am pretty sure its all right, i wired it twice. due to teh bad ground and all and i even ran a new main ground. i checked all my connections and stuff because i used those tube connectors and they dont work too great but they all worked fine this time and all connections are right and are solid. but i do want to be sure before i send my deck away that its not my error. i will have no radio or anything for like 2 weeks

 

when you used the pioneer plug, it was probably different and shorted something out in the radio. it may not have been enough to keep it from playing until you went around the corner. chances are if you have to send it to kenwood, it will probably take closer to 2 months. i think they say 6-8 weeks, but they could be slow right now. ya never know.

good luck,
jacob

 

i didnt use the pioneer plug. it was when it was wired before, i couldnt see the stock wires, just the pioneer ones. and all the speaker grounds were wired into one big ground and it made it over heat. my poineer worked great until it was stolen so then i got this kenwood, it over heated twice but still worked fine. i contacted the place i got it from and they said they would either fix it or replace it. so i have 2-3 weeks to get it back instead of the kenwood time so im pretty happy about that. and to make sure it was the head unit and not my wiring, i took on set of the speaker wires from the head unit and i pluged it into a set of speakers in a box that are in my jeep and it still didnt work so it has to be something in the head unit. thanks for all ur help.

 

“and all the speaker grounds were wired into one big ground and it made it over heat”

Heat kills electronics, maybe not right away but it will “weaken” (for lack of a better word) them, then maybe a day latter or a year latter. Your install killer your radio.
The pioneer harness put B+ on the right rear negative speaker output. Also bad.

BTW, even if you do have warranty Kenwood may not cover it. Warrantys are to protect you for defects in design or manufacture, not your self. They may cover it, but they may not.

 

I told you. But nobody wants to listen to me!

 

i contacted teh place i got it from, since i got it off of ebay, and i told them i think it might be an internal short and they said send it back and they will fix it or replace it since its an electronics store. and needaz, what does The pioneer harness put B+ on the right rear negative speaker output. Also bad. mean? thanks alot

 

That is one of the main reasons I buy my major electronics from local stores. Warranty, customer service, time, effort, money, and a person you can look in the eyes and see if they are lying to you: are the other reasons I buy electronics locally. Don't get me wrong...I buy amps and tons of other stuff on e-bay all the time. But I only buy things that are factory warranty and will have to be shipped back to the manufacturer anyway.

 

yeah, i deffinately learned my lesson. i might buy a set of speakers off ebay here pretty soon though, they are really cheap on there so that makes me wonder about them. i havent decided weather i will or not

 

Get ones that are sold locally and you might be able to do a warranty swap if the e-bay items do not hold up.

 

are you guys positive that the stock blue wire goes to the purple wire? all my speakers worked and stuff and i dont want to mess up my speaker or something. or if not sure do you know if the blue is a positive or a ground? thanks

 

never mind, i looked at install dr and it sais dark blue to purple

 

Some Pioneers use the same plug for their harnesses as Kenwood, but it is pined out different. If you look at the Pioneer harness and Kenwood harness side by side you’ll see that on the Pioneer harness the red wire is on the bottom second from the right. On the Kenwood harness the green with a black line (rear left-, I said rear right, sorry) is on that pin. So if the Pioneer harness was wired in to the car right and was plugged into the Kenwood HU you put B+ on the rear left negative when you turned you car on. This is VARY bad. Taking any of the speaker outputs to ether B+ or ground will at least make the internal amp over heat, but usually they will just pop right away.

Also, having all the speaker grounds wired in one big ground (Also VARY VARY bad) would make that amp IC over heat. The black stripe on the speaker output leads is not that speakers ground!!!! It’s that speakers negative. The difference is that if they where ground the output potential would not change, it would always be ground. But that’s not how it works. The wires with the black strip will actually go positive (now you have ground at the speakers positive lead and positive at the speakers negative lead). So the speaker will see that as negative, or reversed polarity. So the speakers will see positive 8V and negative 8V. That’s like the speakers seeing a potential of 16V. It’s an easy way to get more power out of the headunit. This is a vary simplified way of explaining it. Get all that or have more questions?

 

thanks for all the info. but when they stole my pioneer they took the wiring harness with it so what i meant is i just matched up pioneer colored wires with the kenwood colored wires, then later on, after it over heated i found out that all the negatives were wired into the ground wire. thanks alot for all the info

 

Now I got ya'.
