DISCLAIMER. This wire is not full sized. It is RAPTOR/Metra wire, so I'm going to call the Raptor 1/0ga wire 2-ish-gauge to be safe.
Kits are labeled as OFC (oxygen-free copper).
So....
They come w/ Wire terminals, zipties, and 4ga grommet (not sure why its 4ga?, main power wire will not fit in it???) ~18ft RCA (1x) ~18ft remote ~3ft '4ga' silver ground ~5ft '4ga' silver ground ~3ft '1/0' silver ground w/ ring terminal attached ~3ft '4ga' blue power ~7ft '4ga' blue power ~18ft '1/0ga' blue power
DOES NOT INCLUDE Distro-block or fuse/fuse holder. Knife in the pic. (contact Paul if you want one of those)
