Originally I planned on having a pair of Orion HP 12s, with dual 4ohm coils, paralleled down to 1ohm in a ported box. My oldschool Orion HCCA250 would give them approx. 800W. Today I came across another pair of the same subs(identical specs) in a sealed box. So here are my questions????
1. Will (2)12s at 800W(1ohm) be louder AND create more air pressure than (4)12s at 400W(2ohms) given they both use the same cu in airspace per sub?
2. What are your opinions on mixing a sealed & ported box in the same SUV?
3. If I paralleled all the 12s down to 0.5 Ohms , what are your thoughts on adding (2)4ohm 8's paralleled onto the 0.5 that'd give me 1.5 ohms ? Mathematically this works but not sure it's practical?
My goal is to increase audible volume & air moment. I'm open to any suggestions using the equipment I already have. Thanks.
