I have done a search on this topic but I still have a couple questions.  I have a Pioneer AVIC-N2 and two amps and would like to use the remote turn-on lead from the N2 to turn on both amps but I am worried about the current draw.  The posts that I've read say that connecting two amps to a head units remote turn-on is OK but if you want three or more you need to add a relay.  I have no doubt that this is true but I'm just a bit confused because the installation manual for the N2 shows three amps sharing the same turn-on lead and does not say anything about adding a relay so I was wondering if maybe Pioneer's turn-on lead put out more current than other head units' turn-ons.  I don't really care since I will probably never have three amps but it just something I'd like to know.  I should be alright sharing the one remote turn-on with my two amps, right?

yes, you will be fine with running the 2 amps of the remote turn on wire... if you wanted to run fans or anything else off the remote wire, you'd need a relay, (diagram available in the relay section, under special applications) and for about 3 bucks, you are safe for all future upgrades... and just as a side note, Pioneer's remote turn on wire isn't any more powerful than any of the others, they just show you how to wire multiple amps off the wire, if there were 5 amps in their diagram, they would still show them as all on the stock wire, without any relay involved, because that is something 'custom'....

but in the end, if you are sure you will never want another amp, or any acc. turning on with the amps, then by all means don't bother adding the relay, but for 3 bucks, and a few simple connections, I would rather the peace of mind knowing that it's ready for future upgrades..

Agreed... I'm running 2) a2400 class d's and 2) ab 520's  all 4 on h/u remote.

It takes about (dont quote me).5 to .7 amps to turn on amp

                                                     and 50 volts to turn me on (LOL)

Actually it takes less to turn on an amp.  Most decks only put out around 500mA (.5A) max for an amp turn on.  That being said, if you are trying to power on more than 2 amps (or accessories), it is highly recommended to use a relay.
