I'm building a sound system stack. I'm completely starting from scratch though. I'm thinking of two folded bass systems (4x15"), two mid-high cabinets (4x12) and high treble (maybe 12" and a bullet tweeter). Will this be excessive - I'll be doing small enclosed clubs in Sheffield.

I want to play dub, reggae, and ragga-jungle. 

Could you recommend any amps/drivers that will perform well and at a reasonable price?

I'm also ignorant to the wiring which I should use to attach the drivers to the amp.

Any help/advice would be great.
