The system I had in my last car, the installer used a 100amp Phoenix Gold circuit breaker instead of a fuse. Is anyone else using a circuit breaker in their car?

I love the circuit breaker. This is the first time I have used one and it's great. I can just hit a button and trip it every time I want to kill power to the amps.
Hate messing with fuses...

Understand that fuse and circuit breakers have different time reaction speeds. A fuse blows much faster where a breaker will suffer a bit longer before tripping. Depending on the fuse that number can be like 250% of rated current for many seconds. Just something to be aware of.

Paul! Long time no seeing you! Hope things are well! I hope to get to that Farenheit Installation Soon ... waiting for you to tell me when you're arriving so I can make sure the BBQ is Hot and the Beer is Cold ...

Well, I think typical installs have a fuse or breaker at the battery, then a fuse at the distribution block and the amps are also fused at the units. Since there are still 2 fuses, I don't think it would be a problem with a slow breaker.

+1. The breaker insures that the power wire leading from the battery to the main distribution block does fry and the fuses at the distribution block insure the short run of wire between the block and the amp doesn't fry. The small blade fuses on the amp are the last line of defense for the amp.

IN my case, i run a "0" guage pwr wire from the battery to my distribution block. This type of cable will accomodate a huge amount of current, so I have to have a 120a crkt breaker. At the distribution block I use 60a fuses. Much smaller current rating, but not too much current is being drawn from the block to each individual amp via the 4-gauge pwr cables.
