Shouldn't the 1.2K be a better match and pretty much blow the 500bd out of the water. Well we have it hooked up to the 2 level 3 10's, still need to do some fine tuning but it seems either the same or maybe a little weaker. Just wanted to get some thoughts. It's on stock electrical at the moment in a cab in half 2005 Ford Ranger. Just thought that would be a huge difference effectively doubling the power.
