Sup Guys, hailing from Orlando. I was going for the Ethos 18 for my Durango, but they sold out so i opted for the Trident 18. From what i researched, it's an etho on steroids lol. It truly is a beast. I spoke with Q and my sub should be ready sometime this week. I will be running it off my Taramps hd8k. I will post pics once i get it. This is what Q told me about box specs for the Trident, "You will want to go at least 5 cubes tuned to 32 hertz per 18. Go around 7 feet per sub if you have the room"
