I hate that i didnt install the radio so I need to confirm what wire i would use from its massive bundle (theres a small amp under the dash too)

At this points..circuit choices appear

run from radio
run from ignition
run from fuse box
some one suggested clock but that always on so would i just double the battery drain running a voltmeter when no one is is the car :-)
