I have question on what 10" sub to choose and what ohms. Its for my room. I know car audio isn't the best for home use. Anyway currently i have a small sealed q logic box for a 10", right now it has a sony pentagon sub, so i want something with better sq for less than say $100(ebay). I was considering the Alpine type-S 2ohm DVC and i would wire it in a series,i think this makes a 4 ohm load. My reciever puts out 160RMS at 4 ohms. Any help greatly appreciated
