Pre-Competition Week

Electrical system verification:

1. Charge all batteries fully 24 hours before event
2. Load test batteries — verify voltage stays above 12.0V under simulated competition load
3. Clean all power connections — wire brush on terminals, re-torque, apply dielectric grease
4. Check alternator output — should maintain 13.8V+ at idle under load

Mechanical inspection:

1. Check all mounting hardware — every screw, bolt, washer tight
2. Verify enclosure integrity — no air leaks (use incense smoke test)
3. Test for panel resonances — press on panels during playback, listen for rattles
4. Inspect wire routing — no chafing, no stress on connections

Audio system verification:

1. Back up DSP settings — export configuration files, email to yourself
2. Verify speaker polarity — all drivers moving in correct direction
3. Measure system response — REW measurement for reference
4. Test at competition power level — confirm no thermal protection, no distortion
