• Power connections made through a large 4 gauge removable terminal connector. (Dual 4 gauge connectors of the
HCCA 275
R
)
• 4 Gauge power and ground wire recommended for optimal performance. (Dual 4 gauge connectors of the
HCCA 275
R
)
• Minimum 8 Gauge power and ground cable is recommended for acceptable performance. (Use only 4 gauge power wire
on the HCCA 275
R
).
• Connect 12V+ to the battery through fuse holder. This connection pr12V main power to the amplifier.
• Power wire must be fused less than 18” from battery.
• Ground amplifier to a good chassis ground as close as possible to the amplifier.
• Connect REM terminal to remote turn-on lead from source unit. This connection pr12V power to turn-on
the amplifier.
• Add Extra Ground wire between the negative terminal of the battery and the chassis.
NOTE: The addition of a ground wire from the battery to the chassis of the vehicle improves the ability of the battery to supply
power to the amplifier. This helps especially in newer vehicles, where the current delivery of the factory electrical system
was designed only to accommodate electronics supplied by the auto manufacturer.
WARNING: The HCCA 275
R
has two seperate 4 gauge power and ground inputs. Both pairs of connections must use 4 gauge
power wire for proper operation. Failure to do this may damage the amplifier and is not covered under warranty.
