I installed a Rockford Fosgate PS300-12 powered sub today. It couldn’t have went any better. It’s so easy with the swingback as there’s tons of room under the huge lounger. The best part is that the batteries are right there for power and I have the stern speakers so I was able to steal signal from them. Plus with this sub you don’t even need a remote wire from the head unit so there’s no wires to run at all. Everything you need is right at the back. Super simple and sounds great!
