I'm going to get 2 12w3's. they're 250 watts rms. I was going to get a jl 500/1 because that's what i was told to get, however i've read a lot of reviews on rf, and it looks like they are good as well and they're cheaper, but i've also been told that if the amp doesn't go with the sub well it doesn't sound good. What amp should i go with, or which company is a good company to stay with??
