Checking your work, testing and burning in time
Carefully check wiring connections against schematic
Connect XO to speaker panel, then speaker cables to XO, then speaker cables to amp.
Make sure that all mechanical connections especially binding post nuts are tight (tightened with wrench and not finger tight otherwise there will be a loss of dynamics and transients)
Turn amp on and add power gently.
Note : Caps take about 14 hours to burn in
