If I get an amp around 1,200-1,600 watts to drive my 2 Audiobahn AW1200q's, and keep my existing 400 watt amp, I just want to make sure I have enough juice. I know I need a cap but If I spend around $150, might as well have 100 farads than 1, right? I just want to know if they are reliable and produce good results.
