Distribution blocks & such

[mikecdm 0]

Well I am slowly trying to improve the sound in my 2001 bmw 325i and I think I know the answer but I'm not completely sure. Currently I only have one amp which is powering my subs and then there is the factory amp thats connected to all the factory locations. Since my battery is in the trunk I have a big fuse holder about 1ft away from the battery then it runs to the amp.

Today I should be getting some of those PG rds components and when I finally by some sound deadening I will be installing a 4ch amp to run those speakers. In the past I used a fused distribution block as well as the single fuse holder by the battery, but this was in a camry. I was wondering if I would still need to have a both since everything is going to be in my trunk and the longest run is probably going to be around 5ft. I plan on running 1/0 gauge then splitting it into 4 gauge to each amp. I probably don't need to, but I figure that I might as well do it right the first time.

Could I use the fuse holder by the battery then one of those blocks that just splits it into two w/out fuses or do they need fuses. The other option would be to run the power cable all the way to a fused distribution block with no immediate fuse holder by the battery.

The amps I have are cheap amps which I plan to upgrade in the future. I will probably upgrade my subs and amp to the icon/sae1000D but before I do that I really want an alpine 9887 then eventually I'll buy a better 4ch. But in the meantime I am going to run things of the factory head unit using a LOC. I was also thinking of bridging the 4ch to run the components, does this sound right. I don't plan on using any rear fill either.

You only need a fuse if you need to protect the wire. If it were me, I'd only run the one by the battery but I'd be real anal about where I ran my wires. If you are lackadaisical about that then you should fuse.

that should answer all your questions and help you with how big of fuses you need. Personally, I'd fuse them all. I'd rather be safe than see my car catch on fire. I'm pretty anal too, but I don't know how far anal would carry me in an accident...
