could someone tell me what the fuse location is
for the constant power lead to the radio
on the 99 civic ex?

I thought it was 28, but that only gets power when the switch is on.

thanks

 

On my Integra, there is a fuse under the hood that goes through the radio / clock. It might be worth a check.

 

get a light tester and go under the hood to locate the radio fuse. The diagram in the fuse box should say which one is the radio fuse. Make sure you have your car key turned(dont crank car) before you check.

 

In ALL Hondas there are two radio fuses! One under the hood, and one in the fuse panel. If you are going to replace you factory head unit, find the 7.5 amp fuse under you hood and replace it with a 10-20 amp fuse.

 

Why is this? Does an after market HU require a bigger fuse?

 

Some do, It's just good to do it because 1 most people don't know about it and 2 most aftermakert head unit run off of a 15-20 amp.

If your car is pulling alot of power, EI multiple amps or electronics in your car, that 7.5 amp fuse will be the first thing to go.

 

:thinking: But the amps run off of their own power lines.

I say just replace that dinky 7.5 with whatever size fuse is on the HU then add a few amps for the clock. I have a 15 in there right now. My 7.5 kept on popping.

 

yeah but most of the upper lines of head units need a pretty good source of power to operate correctlly. Like the Alpine A series of head units (example CDA-9833), they have an enternal V-drive amplifier built in, and require a little bit more power than lesser models

 

Some of the alpine head units tell you in the directions to run the constant to the battery. I also have a 15amp in my 7.5 location and it does me no harm.
