As for the wires that need to go to a switched 12v just tap into a switched 12v source. Don't cut factory wires. Splice with a vampire tap / posi tap if you have to.
Thanks.. Also the static was never there with stock head unit so not sure what it could be. The amp the subs go to are grounded well. Never had an issue with the amp. Just as soon as I install an aftermarket HU, I get a ton of static.
