Please read the spec of your amp and what power output, like 600 watt to 1 ohm or 8 ohm.....
What ohm are your speaker, make sure you check is it a Dual 4 ohm or dual two ohm?
Your subs are single voice coil, you can either wire them into an 8ohm load or a 2 ohm load. To obtain the 2 ohm load, connect all the positive ends together and likewise all the negative ends. This is called wiring in parallel.
