help me fuse my system please

The fuse is designed to protect the vehicle and it's contents from damage (fire)caused by a short circuit in the power line. It's size is determined by the combined value of the fuses in the amplifiers to be used.  It is ok to have a fuse (or breaker) that is larger than this combined value but should not drastically exceed it. The fuse goes ideally no more than 18" from the battery on the power line running to the amplifiers. There is no need to fuse between the alternator and the battery.

The only reason that you would used a fused distribution block is if the amplifiers do not have fuses built into them, do your amps have built in fuses? With the questions that you have asked, I think it would be prudent to list as much information for us as possible, this means vehicle type, year, equipment etc.

Rob,

Here is waht my final setup will be:

PG Limited Edition Octane Amp<<Basically this consists of (2) ti400.2's with a 1F cap and Bass cube built into one casis. (Subs and fronts)

PG ti400.2 (Rears)

APC 350w Power Inverter (powering Xbox console, and possibly camera or laptop)

(2) JL 12w6v2's

98 Accord Coupe 2.3L Vtec, I will upgrade the alt and probably use one yellow top battery. let me know if you need more info! thanks for your help so far. [I hope you can read my chicken scratch drawing below]

I read it here. So I should NOT fuse betweem the alt and battery? Perhaps only for smaller guage wire? I think the guy who wrote that tutorial used 4 awg...

"6) Run the wire either through your fuse box if applicable or through a fuse. The fuse should be sized to match the max ampacity of your wire, not the output capability of your alternator. As you can see I just went through the fuse box, so my upgrade is probably not making as much of a difference as it could if it were fused externally, but my alternator is capable of withstanding the draws anyway so I'm not particularly worried about it. If I ever begin to see a problem w/ current draws, I will probably fuse the wire externally with a 300A or so fuse..."

THANKS FOR HELPING!!!!!
