People, the fuses in both of the amp equal 250 amp or what ever. I only put down the fuse rating because I thought it matters in which relay to use. Sorry for the confusion.

The fuse rating on these are are rated at a safe amperage where the fuse will burn out to protect the circuits of the amplifier. If each amplifier is rated at with a 125 amp fuse ( just for comparison ), then the total amperage required to blow the fuse is 125 amps but chances are the amp can take more than that, but the manufacturer's being on the safe side.

Back to the original question, the remote turn on lead is what will turn on the amplifier and the fans from the HU. Most HU's can handle 2 devices from the one remote turn on lead without problems. If more devices are added, then a relay ( SPDT 30/40 amp ) is recommended to be installed regardless of wattage or amperage of the amp, fan or HU.

Hope this clarifies some things here and please remember that we're all here to help one another. Getting all excited about relays and wires is not necessary and IMO, very juvenile. Lets keep this forum as professional  as possible, thanks.

Hey John, I think what Teken was trying to point out was the fact that the output of amplifier's are rated in watts and the consumption is rated in amps. With the original posting, the question was about the fans and the amplifier turn on in relation to the HU. In which case the MAX ampheres have nothing to do with what is needed to answer his question.
