From what you did write, you've got the amp bridged into a 1ohm load = not too good for the amp (or the sub, really).

These are the 2 options you have; https://www.the12volt.com/caraudio/woofer_configurations.asp?Q=1&I=22 -from what you wrote, you've got it wired like option #1 (1ohm). You want it to be wired like option #2 (4ohms).

ok is there a way to achieve 2 ohms with maybe using a dual voice coil 4 ohm and a dual 2ohm subs together

Run the coils of the dual 2 ohm in series for 4 ohms, and parallel it with ONE voice coil of the dual 4 ohm woofer (leave the other voice coil completely unconnected). There's your 2 ohms, but your dual voice coil 4 ohm woofer will have reduced power handling - about 25% reduced.

But generally speaking, no, there isn't.

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."
