Hi, I am planning on getting 1 12" alpine type-r and I wanted to pair it with the JBL BP600.1 inside a ported box. I guess I need a subsonic filter, which this amplifier does not come with.
I heard of the F-Mod, but have no idea how to connect it or anything like that. What kind of F-mod would I need? If anyone could help, it would be greatly appreciated.
