•Power connections made through dual large 4 gauge removable terminal connector.

•Dual 4 Gauge power and ground wire required for proper performance.

•Connect 12V+ to the battery through power distribution and fuse holder. This connection provides +12V main power to the amplifier.

•Power wires must be fused less than 18” from battery.

•Terminate both grounds for 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 provides +12V power to turn-on the amplifier.

•Add Extra Ground wire between the negative terminal of the battery and the chassis. Either dual 4 gauge or singal 1/0 gauge.

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 275R 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.
