Alright all I really need some advice heres my options. Current subs Kicker s8L7 x 2, I have an offer to get my buddies 2 JL 10w6's for half of new they were gently used he buys top end stuff but babies it hes great guy for second hand. or I was thinking about either 2-4 Sa-8's or skar Ma-8 or cadence w2s8 My current amp is a HIFI 1500.1. I know if I go 4 subs I need to upgrade or add amp. My question to everyone is out of those what do you think? I am leaning to the JL's but I am open to suggestions just to put it out there im not looking to go over 300-400 on the subs since that is what hes asking.
