DC ERROR

Hey guys,

So I installed 4 new speakers in my truck and 2 pioneer 6x8's in the front and 2 kicker 6x8's in the back. my buddy wired them up very nicely (shrink wrap, sodered, ect) but sometimes when I turn my truck on an error message comes up on my headunit (alpine) that reads DC error. Usually thats a grounded speaker wire or shorted wire but we checked them 3 or 4 times and none of them are grounded. We also used a multimeter to measure how much power each speaker was getting and one of them was getting much less. do you think I need to replace the speaker wires? has anyone else had this problem?

are you sure you didnt pinch a wire putting the panels back on? check the wires from the head unit as well, i have seen many rubbed through wires behind the dash

I would pull the head unit and check behind there for some wire issues if you haven't already.

id check for ground on the wires to the low speaker.

with the volt meter, touch a positive and each wire. If you get a reading you have a wire grounding out on the body.

stereo off, truck on.

What about the head unit ground ?
Should there be a separate ground from the head directly to ground ?

I actually just took the face plate off today and put it back on and it seemed to work a bit. turned the truck on later and it was reading DC error again, so i fiddled around with the faceplate a bit and it popped on again.

I definitely think it has something to do with the headunit after messing around with the faceplate. but I'm no techno whiz so I don't know what that could mean?

It may be a ground on the headunit though bc a reason for it working sometimes may be me hitting bumps and causing a wire on the deck somewhere to ground itself back there.

I actually have checked every speaker with a meter and they all seemed to have power getting to them. I'm beginning to think It really is something to do with the head unit

Just reading your thread again !
The only thing you have changed are the speakers ?
You say you have checked the wires and soldered the connections but what about a poor solder joint causing a bad connection.
Did you take apart each connections and look at the joint ?
Also replace each speakers, one at a time, and see if the error goes away.

I would run new heavy gauge speaker wiring no matter what you find; new could could mean better sounding speakers and if you decide to go to an amp then the wiring working would already be there.
Don't use 16 ga lamp cord, buy some good quality speaker wire, I like StreetWires, might work for you and think about further plans.

GLW the wiring...

I guess I forgot to mention that I have an aftermarket headunit also. It's an Alpine. It's in my sig but I should have mentioned that. It was also installed by Best Buy over a year ago so that makes me wonder about the quality of that job aswell. I may have disturbed it when taking the dash apart or messing with the speakers.

I like your idea about the higher quality speaker wire though I just hate the idea of having to take my door panels off again and rewire the speakers for a third time lol

Taking the doors apart is a PITA but if the new wiring works then it will be worth it.
If you take the head unit out, which I think you need to for the new wiring, add the chassis ground from the radio chassis to a good ground point.

Also, since this is a new head unit, do you have the manual, check it out or go on line to the Alpine Sitet and see what they say about the "DC Error".

Luck to ya, just time now and new wiring...
