Hahaha SSA built by Fi? What are u smoking? Aaron Clinton owns SSA and everything done by them is designed and done by them, they have no affiliation whatsoever with Fi or anyone else aside from maybe knowing people that work there. As for American Bass being garbage you are again incorrect. I have 2 xfl 12s in my car right now that bang like crazy and sound clean and clear doing it. The vfl and hd series subs are spl geared, the xfl series is a straight sql monster.
