Here is what i think i have to do. I want to run my 0 ga wire from my battery fuse and all to my positive to my 3 power caps. I'll ground my caps and use the last power caps positive and run a zero ga wire to a distro block. then i will run 3 4 ga wires to my 3 amps. then my remote turn on nleads i will link from the last amp to the scond to the 1st and run that to the head unit. Is this correct and do i need fuses inbetween the distro and the amps if the distro has fuses? thanks

I think I understand what you are doing. Just make sure that you use 0 gauge wire from the battery all the way to the amps (to each cap also). If the distro block has fuses, then that will work just fine; no need to add another. As for the remote wire, run it from the deck to the first amp, and splice it into a relay to help increase the power to the second (and third) amp. I've heard of people using a relay before each amp, but I don't think this is necessary. Just one relay per two amps. The reason for this is because the remote wire from the deck is not quite powerful enough to turn on multiple amps. The power decreases with each amp you connect and the hu will not supply more power to make up for this, hence the relays to another power source.

My caps are all hooked together with top mounting bars is that still ok to use the last positive to run to my distribution block? o think i should run zero gauge after my block to my amps? And where would one get a relay for that? thanks

Top mounting bars work to connect eh caps. I meant to say to use the 0 ga to the distro block, the a smaller wire to the amps (depending on the power they consume). Sorry for the misunderstanding. As for a relay, you can get them at most any automotive store. An example would be like this: https://www.partsexpress.com/pe/showdetl.cfm?DID=7&PartNumber=330-070
You should wire it like this: https://www.the12volt.com/relays/page5.asp
Scroll down to "Connecting things to the remote wire".
