Installation Location Options
Choose your installation location here. All harnesses are sized based on your install location, so be sure to choose correctly.
Install Kit Options
The subwoofer must be powered directly from the battery or a portion of the power distribution system. The current draw is too high to power off an existing circuit in the vehicle.
The base harness comes with (2) 12" pigtails for the power and ground wires
(12ga TXL) to the KEY200.4. Choose this option when you have your own power and ground wiring and all fuses and terminals needed for the installation.
Budget Install Kit
The budget install kit option gives you everything you'll need for your installation, for you to install yourself. This option includes a power wire sized based on your vehicle and install location, a 3' ground wire
(12ga TXL), a fuse holder and fuse, and ring terminals. Everything is shipped loose for you to install in the vehicle.
Premium Install Kit
The premium install kit option gives you everything you'll need with a pre-installed waterproof fuse and ring terminals for attachment to the battery and chassis. This option includes a power wire sized based on your vehicle and install location, and 3' ground wire
(12ga TXL) in nylon-braided sleeving. No extra work is required beyond routing the wires and attaching them to the battery and chassis.
