Future System Expansion Planning
Consider space and cooling for future system upgrades.
Input Level Selection
Discusses using Low-Level (Pre-Amp) or high-level inputs for amplifier connection.
Component Matching
Ensures speaker RMS power rating is equal or greater than amplifier's, and impedance is 2-8 Ohms.
Amplifier Installation Location
Advice on mounting location, wire routing to prevent noise, and RCA cable requirements.
Wiring Connection
Recommended Wire Gauge
Recommends 4/8 gauge for power/ground, 12 gauge for remote, and 16 gauge for turn-on wires.
Ground Connection to Chassis
Essential to ground amplifier to clean, bare metal chassis surface, not exceeding 3 ft.
+12 Volt Constant Power Connection
Connect directly to the positive battery terminal with an in-line fuse holder.
