I am running a power wire less than 10 feet form the battery to a distro block. From the Block I will be powering one 60x2 amp (speakers)and one 300x1 Sub amp. so a total of like 420 RMS watts. I can get Deka 6 Gauge wire for free at my work But I do not know if I need to bump it down to 4 Gauge.


So what do you think 4 or 6 gauge for 420 RMS watts

    technically, for that run, you could get away with 10 awg. i would feel for comfortable with 8, but 10 would work.

    so... 6 is plenty large enough, and 4 is just plain overkill.

    Wow are you sure?

    Should I use a fused block or just put a fuse next to the battery on the cable?

    Forget the fused block. If your amp already has a fuse in it and youve got one at the battery, adding another will only add resistance to the line.

    Just use a normal dist block.

    so why not run a fused distro block? That's what I've run for years. To rely on the fuses in an amp is almost to late in most cases. I fuse the power cable (within 12 inches) and then the block to protect each amp. Resistance, sure but honestly how much resistance can it really cause?

    Safety, yes. Bird with a parachute, too much.
