Multiple Amp & Distribution Question

**Shelbrain** · 04-23-2005, 03:51 PM

In my new car, I am going to be running two amps (not at first) plus the carputer.

I will be running two Alpine amps: 4 channel amp + sub amp. Both amps require 8 gauge power and ground.

In trying to hook everything up, I was looking to run 4 gauge power directly from an yellowtop Optima battery into a distribution block (which one?)

and then from there split it three ways to the amps and pc

As I said before the amps will be bought in stages, so far now I want to lay the foundation for everything and do it right from the beginning.

I think this is what I need for two amps and the PC:

Would any of thise blocks work? I wasi thinking the other product because it would make grounded the amps and the PC to the same point easy.

Don't use a block on the ground. You want to use a star ground. Bad grounding methods are the cause of 90% of noise in systems.

why can't you use a block? ... if I'm not mistaken, connecting all grounds together and then a single cable from that point to the chasis is one form of star grounding ... with this method using a non fused distro block establishes just that.

I certainly wouldn't recommend using a fused block for ground ... but I don't see any problem with using a non fused block.

Don't waste your money on a fancy distro block. Head down to your local electronics shop (in australia we have something like jaycar.com.au) and grab a 3 or 4 way fused distro block. Just make sure it is 4ag in and 8ag out. Chuck in fuses appropriate to the equipment and you're all set.

Probably a waste at 80bucks (US!) for something that is just a chunk of metal with some fuse holders and a bit of insulation.

I gave the crutchfield link only becuase they have large pics and detailed info about their products. I have a distro block for power, but I don't use one for the ground. I just have them all bolted in one place...
