Get one more of the same sub, over power the sub bout...eh 100 more rms. I hear type r's can handle well. if you deside to get another one, which you probably will cause youll always want more bump for your trunk the pdx 1000 for alpine is a pretty good choise if you wanna pay an arm and a leg for it. some good amp brands are sound digital, jl, alpine, kicker, sundown audio, audioque, mtx?, orion +alot more. Hifonics is a decent brand for the buck, they have a better looking design then they do material inside "haha" get a ported box like the others said and set it to those tunes also. uhhmmm you werent really straight forward on what yr looking for soooo idrfk what else to say lol
