crossover, eq power

My situation. Drive a 2002 for explorer 4dr. Kenwood 655, audiocontrol eqq, audiocontrol 4xs, soundstream class a Picasso, soundstream class a 10.0. 4 infinty 5 1/4, 4 idq q 12's. I'm looking to power my eqq, 4xs, mbr70. I have a second battery with 0ga going to splitter. 4ga going to amps. Have relay running all remotes. Where should I get the 12v for them smaller equipment. Thinking about enclosing my amp rack and putting in a couple of fans. Though about another relay that would come on and off with the ignition like the radio. Where would you pros get your power from? Thanks for all the help.

i would connect them directly to the ignition harness with a fuse on each line. you can use the brown wire or BLACK/ green wire. this way you wont be stealing power from your radio harness. this is the way i ran all of my extra stuff when i still had my 01 ranger. btw, the ignition harness is the main set of wires that comes from the key cylinder. you will have to take the under dash panels off to access it. or, you can run a constant wire to the battery and switch it using a relay and your radios remote output.

that's what Im wondering. I was going to run some smaller gauge wires to the same splitter as my amps come from. figured there was another way to get the power back there without having the smaller gauge wires in my 4 ga splitter

yea i woudnt go to your distribution block that your amps are on. technically theres nothing wrong with doing that but there are just better ways to go about doing it.

thanks for the info and help. love this place.

is the ignition harness in the steering column or under the drivers side of the dash. does the brown wire or the black green wire goto 0 volts with the key off. it appears they are accessory wires and they do.
