Need some guidance here.

I'm going to be running 2 Amplifers (80amps; 40 Amps), 1 x-over (10amps), 1 powered Distribution block (unknown amps, but does use a 200 amp ANL fuse for my 2 amplifiers).

How should I go about connecting all the remote turn-on leads? Will 1 (standard 30 amp relay) suffice? Can someone provide me some tips on how to wire this up. I don't want to "overload" my remote turn-on lead from the HU, if that is possible.

Any info will be greatly appreciated.

you should be able to run the three items in series on the remote lead, i think on some previous post i read that up to three amps would run on a remote lead with no relays.

So, how do I determine what size fuse to put on the #30 lead?

Also, should I uses fuses between the #87 and the amplifiers?

A five amp fuse would be fine, if you have a three amp fuse, that'd work also. I think amps only need around 100 to 150 ma current remote lead, and most decks'll give you enough to run at least 2 accessories without any relays- can anyone verify this? I wouldn't worry about fusing the individual leads, if you have a short, 3 to 5 amps is not a lot, so the main fuse'll blow.

Your best bet is to use a relay. I deck handled 4 accessaries with my deck before it finnaly gave up.
