I have 4 Tempests laying around from my old car audio days...Now I have 2 Brahma's Anyway I'm looking for a powerful setup that will kill my 2 SVS25-31 CS+'s w/Sampson1000 amp in my living room. This of course is going into the HT room. I'm thinking about building a raised seating platform and throwing them into that. I have 4 PE250 plate amps from other hobbies that I collected. Any ideas, box sizes, best tuning freq, where to buy earthquake insurance?
