Connecting remote turn-on to several amps

Up above, I noticed what you wrote about your ground distribution- 8 gauge from the amps- 10 gauge to ground.  I hope this is a typo.  Your power and ground cabling should be the same size- if you use 4 gauge from the battery, use 4 gauge for ground as well.  Also, consider upgrading the factory ground wires to at least 4 gauge.  You can do a search on the big 3.

No, you don't have to go to the battery to power the relay.  I'd probably just wire it in behind the deck (use the yellow for power, black for ground, etc.).  Use a seperate fuse coming off the yellow- 3A or 5A will be fine.  You can use 18 gauge for the remote.

Thanks for the info.  Yes, I am using 4 ga from the battery and to the ground.  However I will use 8 ga to each individual amp.

BTW, can I just put relay for the remote turn on in the trunk and run it off of the power cable coming from the battery to the dist. box? 

Nitro,

yes you can power it off the amp power.

Jlord,

yes you can pick up relays at the store- some places have prewired relay sockets, too- you just have to connect the wires.

Thanks to everyone that responded to my questions.  Sorry for repeating this question again but I didn't see a response:

Do I need to somehow step down the voltage going to the the amps from the relay since the remote turn on is ( I think) lower voltage? If so how do I do it?

The remote out from the deck is 12V. No step down at all.

Thanks allnpt0.
