yup. I have installed 4 gauge kicker hyperflex in my car and my girlfriend's mustang. I have welding cable and audiopipe 1/0 wires in my car now. I will try to replace the audiopipe with the welding cable soon though. They aren't as flexible. //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gifo'really?
