This is a 1/0 AWG Copper amp power kit that I put together using my EB Flex Copper welding cable which is made in USA.
 
Some of the key features of this amp kit are as follows:
AWG rated cable is heavy duty with a double thick rubber insulation that is made to withstand all the elements underhood or undercar.
Flex loom for extra protection
ANL fuse holder with 250a fuse
Comes with hydraulically crimped tubular tinned copper ring terminals (the best)
Ring terminals hydraulically crimped to save you time and effort as the installer
Reference ground wire to reduce ground loops
Real grounding solution: Predrill a 1/4" hole, scrape the paint away, and the grounding lug will tap its own threads providing a solid ground for you.
 
This kit comes with:
17ft 1/0 AWG Copper power cable covered with flex loom
3ft 1/0 AWG Copper black ground wire
17ft blue remote turn on wire
17ft reference ground wire
#FAM ANL Fuse holder
