Nice write up. Just gotta clean up those wires with the masking tape a bit.

Yeah, best to go back and use insulated spade connectors or at least some electrical tape. You don't want any short circuits

You found Blue Remote wire back there?
Are you sure power shuts off on this wire with key out? I recall testing all wires with Factory Wiring diagrams and did not locate a single Accessory or Ignition wire at the factory Amplifier at all.

Also i Recommend you redo the wire going through the firewall, it does not look like you punched hole through the Rubber Grommet> it looks like more like you popped the Grommet off and got the wire to pass through but going around the Grommet. Over time this will may rub through the wire insulation but rubbing against metal edge of hole. Also this gives water a way to enter into the cabin because the Grommet not giving a good seal anymore due to power wire in the way now for the grommet to seat and seal correctly.

Thanks for the write up, but as someone who was a professional mobile electronics installer for 7 years there are some glaring issues that should be pointed out so that people dont have potential issues, first and foremost that power wire running beside the grommet through the firewall, the whole purpose of that grommet is to protect the wires from chaffing against the metal, the power wire should have been run through that grommet, what I did when I did the install on my IS350 was tape the power wire to a coat hanger that i straightened, poke it through the grommet and pull the wire through. Second the remote turn on wire should come from a fused and switched accessory, for simplicity sake I just went to the fuse box and tapped off the fused side of an accessory fuse direct in the box. As for finding the high level inputs (speaker wires) for the amp signal, I just went direct to the factory sub, because the amp will be running mono you only really need a single input source, not a stereo (left and right) source. The ground wire seems to be attached on top of a nut an bolt sitting on a painted surface. personally from experience I know the importance of a good ground, I always scrape paint off and secure direct to sheet metal. And Im not trying to be a **** here... but masking tape... really?? Im sure your setup works just fine, but if people are to use this as an educational resource for their own installs I couldnt not mention anything.
