  • Multiple Amp & Distribution Question

    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.

          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...

                    If your looking for a cheap way out just get a 3 way 4 gauge block,And yes using a solid block for the ground is a very good idea.

                        You'll need a cable(s) to hook up the signal output of the PC to the RCA inputs of the amps. And also speaker wire. Knukonceptz has some decent prices on them as well. I bought all my wire for my system from them. Here's a thread dealing with the signal cable: http://www.mp3car.com/vbulletin/showthread.php?t=48516

                          But do you think that the abovementioned items will work as the foundation for the system?

                              those items will be great. youll always want for more items though, you may run out of ring terminals, you might need spades to get from 8 gauge to your amps, or maye they accept raw wire, youll need a connector to get from 8 gauge to the computer PSU, they never ever ever come with enough zipties to make things clean, etc, etc, etc.
