I have a crossfire 1000d and a 300rms concept amp total 1300rms what size of inline fuse should I have for this? 130Amp?
The amps already have fuses right? The inline fuse should be more for the wire then the amps. What size wire do you have!!!
Congrats you just confuised me I have 4ga wire...yes the amp has some fuses in it...just let me know what size or should I just use the standard round glass 60amp fuse? Thanks h34r: !
look at all the fuses on your amps, and add them all up. Then add, say, 20 amps, and make that your fuse size on your wire, depepnding on what the closewst fuse size is to what you need.
The amps are already protected by fuses. I dont think that 4 guage is big enough for that much power though. You can go here http://www.eatel.net/~amptech/elecdisc/ and see what they recommend I believe it is atleast 2 gauge and a 125 amp fuse. I think 4 guage is only rated for 100 amps at that distance. I would recommend upgrading to 1/0 gauge wire and putting a 150 amp fuse on it. The inline fuse should also be at most 18 inches from the battery. It isnt that important if you are using 1/0 since it can handle 300 amps of current.
Here is that table made reference too. http://www.eatel.net/~amptech/elecdisc/ 4-gauge will do ya, although 2-gauge would provide a little wiggle room. Wire Gauge Current Flow Max Total Amp Power Class AB (60% eff) Max Total Amp Power Class D (75% eff) 0 awg 330 amps 2731 watts 3414 watts 1 awg 262 amps 2168 watts 2710 watts 2 awg 208 amps 1720 watts 2151 watts 3 awg 165 amps 1365 watts 1707 watts 4 awg 131 amps 1084 watts 1355 watts
of course I will have the gain down on my 4channel for my speakers and my amps will never be full so it will never be pulling over 1000RMS probaly
use a 125 amp ANL fuse... glass fuses only come in the biggest 80 Amps and they will melt (along with the plastic fuse holder). I have seen this many times... the fuse doesnt blow but the heat melts the solder on the fuse. You can also use a 125 Amp circuit breaker.
bad advice Old scholl advice, but BAD all the same the Main line fuse IS there for the WIRE not the amps, this is to protect you, your car, and everything else in the case of a DIRECT short which can leead to a FIRE or Worse... Direct shorts can draw in upwards of 200amps of current, dependonh on your battery,and size of your charging system 1300W's of power will most likly be OK on 4AWG but that is the MINMUM, 2AWG is better but I dont see a "hazard" in using 4AWG, you will probally never see 1300W on music anyway
