What fuse should I use for a radio?
Most low-powered radios can use a 20-amp fuse without any issues. However, for high-powered stereos — those that produce 100 watts of power or more — you may have to use a 25- or 30-amp fuse. You may be able to use a wire clasp or harness already under the dash to secure the wiring from the radio to the fuse box.
What size fuse do I need for car stereo?
Choose Wisely: How Big of a Fuse to Use For example: If you have three amplifiers that draw 60 amperes, 40 amperes, and 30 amperes each, then you need a 130 Ampere fuse. If your total draw is somewhere in-between two sizes of fuses, you can go with one or the other.
Why is my car stereo not getting power?
The most likely cause of a stereo not powering up is a blown fuse. Other causes can be a short in the wiring or other wiring problems. Cars are unforgiving environments for electronics, and vibration, heat and dust can all cause premature failure. Vibration can cause wiring to become loose.
How many watts can a 10 amp fuse handle?
1200 Watts
Watts = Amps x Volts Examples: 10 Amps x 120 Volts = 1200 Watts.
How many watts can a 40 amp fuse handle?
9,600 watts
40-amp 240-volt circuit: 40 amps x 240 volts = 9,600 watts.
What’s the purpose of a 10 Amp Fuse?
Its purpose is to remove the slight electrical draws that some circuits have even with the key off, like radio (keeps time). Pull the holder up, then unlatch and flip the fuse cover over to gain access to the 10-amp fuse inside. Since it also powers the cigar lighter, this is probably where it met its fate.
Can a fuse have power on both sides?
You can have power on both sides of the fuse, yet not have it conduct power to the circuits if there’s a spread terminal contact on the circuit side of the connection (just had one on an Intrepid).
How can I tell if my fuses are still working?
The #12 fuse location is central to the circuit, so finding out if power is present there will tell us which way to go. Here are the other circuits the fuse feeds… just in case one or two may still operate. Check a few of these other systems to see if they operate or if it’s isolated to the radio and dome lamps.
Where are the fuses located on a car?
Look under the panel at the far left end of the dash… The fuse is held inside a black colored fuse holder with tabs to make it easier to pull out of the block. Its purpose is to remove the slight electrical draws that some circuits have even with the key off, like radio (keeps time).
