piggy wires.. wow that's the first time i've heard that

actually after tightening, the radio is far less likely to die on me. but it still dies. i've found a good way to trigger the behavior REPEATABLY:

1) car at idle
2) A/C blowing
3) high beams on
4) radio on

if i roll the window up/down, it's OK (radio don't die anymore). BUT: if the window is FULLY rolled up and i try to roll it up SOME MORE... radio dies every time, accompanied by a rougher engine note (my feeling is the added load on the alternator is fux0ring the engine idle).
