I am going to be running a total of 3 amps, and maybe even a corssover and an eq. Is okay to go from one amp to the other with the remote. I.E. hook up to one amp, of that amp terminal go to the other etc. I know the remote is just nother 12 volt wire, but i was wondering it it would loose power causing an issue with each amp turning on thanks.

Most remote wires only supply enough of an output to turn on two sources (2 amps, or 1 amp and 1 Xover).  You should probably wire a relay to the remote.  The pins would be: the remote wire from the deck to 85, ground to 86, 5 amp fused 12V constant to 30, and your new remote to 87.

You can get away with splicing it but I would suggest a relay. Here is a diagram on how to hook up a relay for your remote wire.
•     87 - Constant
•     86 : GROUND
•     30 - Remote Wire Accessories ( amps, EQ's,)
•     85 : Remote Input from HU
•     87a: NOT USED

Aright, so then i hook up the relay and then i can go to each source. Correct? Also, if you could just briefly explain to me how hooking up the relay works with this application that would be great. Thanks

Ok for starters most decks only supply a small amount of current for turn on, most will turn two on without a problem. When you add more equipment then you need a larger amount of current then the deck will put out, this is where the relay comes in handy. Basically what you are doing is converting a small output from the deck(like 200Ma) and converting it into a higher output (which I would fuse at 3-5 amps) capable of turning on more stuff. All you would need is one relay to turn on your equipment.
