Power Wire A Little Short

[don corleone]

hi guys, i am trying to hook up an aftermarket amp and sub in my LS but the power wire is a little short. i thought 17' would be enough but it stops just above the gas tank. i have 3 ft of ground cable which is more than enough but i am worried about the connectivity and maybe some heat issues since it is very close to the gas tank. i was thinking about cutting some of the ground cable and extending the power wire and soldering the two wires together then wrapping them in electrical tape. my other option would be to get an extra fuse and extending it that way. any suggestions?

add a fuse holder to add the 2 peices together.
