The weather-resistant OEM-grade Tyco 26-pin connector is for all needed amp connections, including the following:

Power/Ground: The connector has 12″ 10-gauge power (red) and ground (black) pigtails. The red power wire has a large, in-line noise filter. There is no internal or in-line fuse, so you’ll need to add a 30A fuse near the battery’s positive (+) terminal.

Remote Turn-on: There are two remote leads on the connector. Connect the blue/white Remote Turn-on lead to the +12V remote turn-on or power antenna lead from the head unit. The solid blue Remote Out lead can be used to turn on additional amplifiers. If your head unit does not have an amplifier turn-on lead, see Alternate Turn-on Options (below).

Inputs: The amplifier will accept either line-level or speaker-level inputs. The amp’s input wires are color-coded twisted pairs with female RCA jacks. If your source unit has RCA outputs, you can simply connect RCA cables to the amp. If the source unit does not have RCA outputs, you can cut off the amp’s RCA jacks and splice the source unit’s speaker wires to the twisted pair inputs. (Color codes: Left: white, Right: gray)

Subwoofer Outputs: The connector has speaker output wires for two subwoofers. There are two brown wires (+) and two brown/black wires (-) for connecting one or two subwoofers. The amplifier will accept a 4″ or 2″ load.
