Dual 4 ohm vc's each. Ok read the instruction carefully on wiring each sub for 8ohms then parallel the two subs at the amp for a 4ohm load. This will give each sub 250 watts. Even though you can get more out of wiring for 1 ohm you may like the SQ at a 4ohm load more. Try it.
he told me to come to you guys...so would this be correct im trying to hook up 2 dual 4 ohm speakers to a 1800 watt kenwood amp 500x1 chan@4 ohms 900x1 chan@2 ohms. the speaker 400 watt rms 800 max amp off course is 1800 watt peak...i want to hook both subs to amp seperate ++-- but @ 4ohms to get the 500watt so i dont blow anything.will the 1800 watt split and give me 900 peak to both subs then the 500 watt split and give me 250 watt rms to each?
