To drop the ohms you wire in parallel. If your sub has dual 4 ohm coils you would connect both positives from the coils together as well as join the negatives together- this will give you 1 set of positive and negative wires-this + and - is now a 2 ohm load do the same to your other sub and you have a pair of 2 ohm subs. Wire the positives together from both subs as well as the negatives again and you now have a 1 ohm load. If you have dual 2 ohm coils you can get as low as 1/2 ohm of resistance.As far as i know the jl 500 puts the same amount of power into 1.5 through 4 ohms as long as you stay in that range your amp will be fine
