Also what size power wire and ground wire should I use? I'm going to be using 8gauge speaker wire. Any help is appreciated. Thanks!

You can try the dealer for the exact cables for your vehicle, if they are not obsolete and are still available, no modifications required. But if shopping for aftermarket cables, longer may be better. You can always tie the extra cable up out of the way. If you start with a cable that is too short, you can't make it any longer. You want to make sure that the cables are not touching any hot engine parts, or crossing any sensitive wiring harnesses where electromagnetic fields could screw with electronic components. It may be better to let the local repair shop replace them for you.
