Hey, I would like some suggestions for a new subwoofer for my car. I'm tired of my whole trunk being full of speakers so I'm downgrading from 2 Pioneer TS series subs in a ported box to a single 10 or 12 in a sealed box. I listen to rock/rap and would prefer a 10 but am having a hard time matching one to my amp. My amp puts out 1550w RMS at 2 ohms, 1222 at 1 ohm, and 800 at 4 ohms. I would prefer to find something that can handle the full power. Suggestions please, price will be around 400 for the sub
