has any one ran power to a 2d blazer, i all ready ordered 25 feet but im wondering if i will need to get more, i am running one line from pos to pos on my powermaster and and the pos to amp and hopefully use it for a ground too, any one from experiance think 25 feet will do it

Should be more than enough.

A friend of mine has a 2001 and he ran 20ft from his battery through a grommet on the drivers side with plenty left over.

ok thanks that made me less worried
