I've done some searches and it looks like 2 or 4 ohm. Should I get one specifically for the center dash speaker? When I purchased my 08 GXP a month ago, the center speaker was blown. I removed it earlier this week and it sounds so much better. The vocals were destroyed on everything, especially talk radio. I can drop up to a hundred on it, but I didn't want to go overboard, because I'm not replacing the factory head unit (want my HUD and controls to keep working). Any suggestions? I don't really know much about who the best for car audio value on the mid-high price range. I may change out some of the other speakers if it's worth it, but I prefer crisp clean sound with good freq range over power.
