i got 2 amps, a sub, 6x9's, a mp3 head unit and a dvd player hooked up but i keep blowing fuses, cant i just put more powerful fuses in?

ok rip the fuse out and if it says 30A then its too small, if it does go down to jb.hi fi and ask for 60A (60 amp) will cost $9 for like a pack of 5. Let me know how that goes.

Dont you like having smoke in the wires...........

Let me know how that goes. The fuse im blowing is the radio fuse, it's on a vs, have a look at the fuses where the steering wheel is, it's number 13 and it's a 7.5, but in theory i should just go the next size up? My understanding was each fuse wattage is what it is to disallow u from wrecking whatever the power is going to, so i guess that might wreck my head units if i p ut a more powerful fuse in? or am i wrong and a more powerful fuse should do what im asking. thanks.

what did you do befor it blew

turned the key on to accessories. It's weird everything was working fine then i think it might of been when i turned the mp3 head unit up and it blew, i got home then every time i put a new fuse in and turned the key on it blew again. I think it's just tryin to suck too much power, if i disconnected the dvd unit and turned the mp3 unit down, then hooked it back up it prob wouldn't blow again till i turned it up again. There's a logical answer to this i just have no idea about this stuff but im sure someone here does.

who hooked the head unit up? might be an earthing problem or something cause if uve got amps and ur speakers etc are hooked up to the amps then they will have nothing to do with the fuse for the radio (cd player) thats in ur fuse box. Well nothing really anyway, the speakers and amps wont be getting power from this fuse as u should have a direct power supply from the battery through a big fuse (as stated in the second post) for the amps. more details on who installed it and what everything is running off might help

A fuse is to protect the wiring NOT the device connected to it. The device (head unit, amp) will/should have an internal fuse to protect itself. So no, you cannot just put a bigger fuse in. If you follow what raczy said then you better have the fire brigade on speed dial, because if you get a short to earth or the cable is sized too small, it'll light up Try what you said.....disconnect the DVD player and turn it down. If it still blows you may have a wiring fault. If it only blows when you crank it, you may need to run a larger power wire to the head unit with a larger fuse. Some original photos have not been recovered yet.

Sweet as u blokes are smart thanks for the help monstaS4 and moggy, now i've got the know how to fix it i should be capable. And the first real problem is because im the one who installed it lol. And yeh the speakers and sub are running off the amps and they're power is comin straight from the battery. I think it's just the way i've got the power hooked up to both head units, ill get it sorted.
