Two bottle jacks, two scissor jacks, a Twilight book and 2x4" oughta do it! Left in a municipal lot, on a slope.

From the submitter:

"Well, I have car music again. It doesn't sound great, and I have to manually apply +5VDC to turn on the amp, then disconnect another cable to turn it back off... but it works for now."

I'm jacked up on knowledge, brah!

"Need a lift, buddy?" "Yeah, in more ways than one!"

The four pieces of tape were all necessary too.
