Hi guys, I recommend spending the money and getting a genuine Ford Falcon/Territory audio booster kit off eBay. It only cost me $80 but is worth it because it comes with an in-built amp booster, so you get better quality sound at normal volumes, because the other ones you have to turn up heaps to even hear the music... I bought it off a seller with the ID Knoxford, highly recommend it, only took me 20 minutes to install too! Hope this is some help
