Thread: Amp has no power.. Help! Not Newbie.

Grab your aftermarket head unit and take a look at the fuse in the remote turn on lead. Maybe they upped it to an single amp in recent years, but for the longest time it was fused at half an amp. The current dra on remote leads should be milliamps.

Shadow, I have read a lot of your posts recently. Although you have had some good advice here and there, you are showing a signinificant amount of misconceptions in the industry which leads to bad recommendations. I'd like to know what shop maintains these after 10 years. Please be careful - someone could take your statement as gospel and fry their system/car

Im looking through the web and seeing 1 amp fuses for remote turn on. Looks like I was wrong

Man, looks like I was wrong about a GM having orange as an accessory wire. Oh wait.....

The only reason an aftermarket radio has a 1A fuse is to protect the internal relay, not to keep the current from heating up the wire. Most accessory circuits in cars are fused at the fusebox at 40A+. A 30A would keep you from blowing this bigger, usually MAXI fuse.

90% of the time the only reason you'd blow a fuse on the remote is because of a dead short in which case a 30A fuse would blow immediately. I've NEVER had any problems wiring things up this way.

then why even make any fuses less than 30 amps?
