1993 honda civic hatch
kenwood radio
using wire harness merta radio kit
everything wired up correct

but im not getting CONSTANT Power.... (from the yellow wire)

i can connect the constant to the acc and it will turn on but then it wont keep its memory.

(WHAT CAN I CONNECT THE YELLOW WIRE TOO TO KEEP A CONSTANT POWER CHARGE)

 

You can't use the sub outputs because they are a low frequency output. As for the remote wire, no the headunit does not need it to turn on. It's function is to turn on an amp, nothing to do with the factory radio.

 

damn so what the hell could be the problem.. its driving me crazy

 

How are your fuses? Do you have a constant 12 volts on the decks yellow wire? Switched 12V on the red? Good ground?

 

fuses are good.. i checked the one under the dash and behind the radio

constant 12 v.. i dont know...

ground.. i grounded from radio to radio harness... or should i ground it to the chassis

 

That ground should be good then if your stock radio was working before you took it out. It does'nt hurt to check though.

 

ok take the red wire and the yellow wire twist em together on the harness from the radio and connect it to the red wire from the car if it doesnt turn on the radio is junk or blown fuse

 

all the wires should be color coded, did you use a radio harness? or did you cut your stock harness?

are you getting power at all? important wires are red, yellow(orange), black.

 

Or just use a test light, much easier.

 

brand new stereo? or used? do you know if it was working before you bought it?

 

sometimes the constant on all the cars dont always work fuse or not

 

You're right, so just use a test light. If it does'nt light up then you don't have power. So either a bad fuse or an open wire.

 

good point

 

so u want me to connect the yellow wire from the headunit to the red wire... or connect the red wire to the yellow wire...

and if this works whats the problem and what do i do to fix it..

 

used... guy said it was working

 

the yellow wire is the ACC wire that tells the radio to come on if you connect it to the red wire that is getting constant 12v and it doesn't come on then it is a bad radio

 

No it's not. The yellow wire should be 12V constant, and the red should be 12V switched. Thats why the yellow wire is a heavier gauge.

 

so i connected the red and yellow.. and connected it str8 to the battery and it turned on... so what does that tell me..

 

That says that the radio is good, but you're not getting power from the OEM harness. Have you checked for 12V constant power on the yellow wire, or for 12V switched on the red wire yet? That will tell you where the problem is.

 

on the back of the radio connect the red and yellow wire, then on the wire harness from the car connect that to the red wire , it should come rite on

 

i need a better direction then the red wire.. cuz the constant and the switch neither are red.

 

and does that mean its gonna stay on all the time

 

yea but does it work?

 

theres 3 wires u run off of every radio to get power a red one a yellow and a blk .
blk to negative , twist the red and yellow together
now stock harness theyres black yellow and red
take the yellow and red that u twisted together and twist it to the red wire on your harness from the car

unless its gm then its orange i think for power
