there's no remote on OEM stereo, take it out of the Accessory/radio power GREY for the REM, check it up with a voltmeter that its only +12v when key is on, and off when key off. for the line converter I soldered wires to the back speaker inside the trunk to minimize impact on OEM wiring. all is tucked inside the trunk cover. There's plenty of threads, use the search function, if you will only power an amplifier in mono (subs) you dont need all four speakers.

These would be about the same for the 2010 corolla too right?
Gotta put together a harness tomorrow.

Never mind, connected my new harness and everything seems to be wired to the same as stated above.
