Connect the LINE INPUTS to the Radio/CD with good quality RCA cables.
Refer to the section “Setting up systems after installation for best performance”
2. Crossover Switch:
The X-OVER switch must be in the FULLposition.
NOTE: Minimum final loudspeaker impedances:
3. Crossover frequency control checklist:
4 & 2 Ohms stereo mode or 4-Ohms mono mode
N/A for full range operation.
