http://forum.realmofexcursion.com/showthread.php?t=18022 These guys are trying to say that a fuse is not meant to protect the wire itself...but is meant to protect the car and the batteries...haha
meant to protect the battery? - what a goofball. meant to keep things from catching on fire.. mainly the wire. I'm suprised.. usually the roe guys are quick to jump on things like that..
All this time....I thought the fuse protected the speaker's voice coil??? Wow what a newb I am!!! lol Willy
i thought the fuse was to protect everything from catching fire or welding itself to things. i was told to put a fuse as close to the batt as possible because if your in an accident and your batt shorts out on the car. it blows that fuse and wont let the wire catch fire. also one in the back for the same reason.any"whatever" will blow the fuse first before any fire can start. am i right?or off on something. my first attempt at a system did not have a fuse at the batt and well to make a long story short.you could see where the wire was running.this happend at 3:30 am.at a red light.burned my hand too.had to rip that thing off of my batt.
Hmmmmm, good point... I should join that forum....... Nah, you guys got it under control!!!!!!!!!! Some folks just dont get it....... I like th epost from the guy that uses NO fuses!!!!!!! When his car burns to the ground, let me know, i will then join and laugh at him!!!!!
battcap, that is a hat that smacks you in the face everytime you think you think that a PG product is a quality product!!!!!!! BURN!!!
In the case of fusing the amp feed wire from the battery, the reason you fuse is in the case of a short to ground....When you have a dead short to ground (like the wire being pinched or if were to rub on a metal (ground) surface) between the battery and the end of the cable.....When the wire shorts to ground that means it takes it's path to ground WITHOUT going through a load and it will run as much current throught the wire as your battery can put out (700 amps or more)...That much current will cause so much heat that is will melt the wire and the insulation and we all no how easy it is to catch carpeting and other wiring/insulation on fire..... You want to fuse as close to the battery as possible, because that will protect as much of that wire as possible....The closer to the battery, hopefully the less likely it is to get shorted to ground....Whatever current draw your amps are gonna draw, you want to fuse a little higher than that. If you fuse at 60 amps and your amplifiers pull 80 amps, your fuse will blow.... Basically a fuse is a device with a lead element that is disigned to melt with x amount of current flowing through it....if the current exceeds the rated amount, the lead melts and causes the voltage/current to stop flowing through the circuit.... Also, If you run cable back to your amps and bring it into a distro box, each run from the distro (of smaller guage) should be fused also and that will be determined by the current flow of each of those circuits...if you have one 100 amp fuse right near the battery and you split your 4 guage wire into 3 or 4 8 guage to feed each amp, if one of the 8 guage wires gets shorted, it will melt and burn long before the 100 amp fuse near the battery fails....
