If it's possible. I have a couple 12's that just sit in my room but I don't have an amp besides my phonic max1000 which I've still yet to see if I could rig it so I can use it in my car so I was just gonna use a small 8 inch home entertainment system subwoofer to see if I can use that by connecting it to the rear left. But I've seen wiring schemes with rear left (+) and rear left (-), if anyone can explain how I can connect my regular sub to this 4 wire speaker I'd appreciate it.
