i know it seems like a extra money you have to spend by buying a wiring kit with a larger capacity. but for the non ebayers they can get expensive if you have to keep upgrading. not to mentiong the slight pita factor of re running your wiring. so what i did was, i ran a 0 gage wiring kit, ( but 2 or 4 may be big enuff for you) so no matter your set up you will always have a big enuff wiring kit. i also got a bunch of different size fuses, from like 40amps to 120 amps. that way when your system changes you just have to change the fuse. not every wire
you must not know the basics of fusing, you fuse according to wire size not whats on the amp, the fuse in your power wire ONLY protects the wire between the fuse and the amp, as long as the fuse is as big as the amps fuses and not too big for the wire its ok.
Wire Gauge Recommended
Maximum Fuse Size
00 awg 400 amps
0 awg 325 amps
1 awg 250 amps
2 awg 200 amps
4 awg 125 amps
6 awg 80 amps
8 awg 50 amps
10 awg 30 amps
12 awg 20 amps
14 awg 15 amps
16 awg 7.5 amps
These are the recommended maximum fuse ratings for the corresponding wire size.
your amp wont pull more power (amps) than its designed to so using 4ga fused at 125a going to an amp that has 50 amps of fuses is correct. the fuses on the amp is what protects the amp itself from internal shorts, not the wires fuse.
