    So I've Got My Opus 90W PSU

    Now what ?

    Actually a little more specific question. How do most people wire this to their battery? I believe it to be a little dangerous to have any cables running directly to the battery (rain, etc.), but correct me if I'm wrong. Also installing the ignition switch deal? How would I go about that? I'm kind of skimming the user guide but I'm looking for a little more help.

    crappy topic title.

    Find a hole in the firewall or make one and run whatever gauge wire Kris recommends in the manual to the + terminal on the battery. You may want to use thicker gauge for future upgrades like amps. Make sure you put fuse inline next to the battery.

    You dont need to run a ground wire. The car's body/frame is ground. Just run an 18" or shorter wire to bare metal. I usually try to find a nearby bolt that screws into the car frame/body and squeeze the wire in between.

    The ignition wire needs to be connected to an acc/ign switched line. If you have a nearby socket, you can tap into the + lead there. Otherwise, you can run a wire to the fuse box and find an appropriate lead.

    If you need more help, search google for car amplifier wiring tutorials. It's a similar process.

    You don't have to worry about the wires getting wet, water will not hurt 12v wires.
