Battery cable too short, can i.....

...Chomp the positive cable down a lil more then fit a 4guage cable extender then run 4gauge audio cable to the positive on the battery??

What happened was the clamp was too loose and broken so i cut it off and fitted a gold car audio but it was just a little too short so i couldn't clamp the battery in place and the cable comes out of the clamp as the battery is pulled right over to the left and moves slightly. Which means it just dies once in a while and i have to connect it back up which could be dangerous i guess.

Haha on a Friday night in Norwich i was driving past riverside, loads people and cops everywhere as you could imagine being Friday night, it died blocking the road which was very busy. I called the cops over to push me and they sort watched as i put the cable in and i got told off for it not being secure, he let me go after saying i'm sorry it wasn't my fault it's my hampsters for nibbling the cable. :dance: He was a lil confussed haha.
