Thats exactly what I bought but I wired them in as per the factory 240 wiring which I think was in parellel but if feels as though they're not that hot. Or maybe it's the ebay quality that's causing this
P (watts) = VA
So given a constant A (it's not actually constant but let's pretend it is), in parallel V=12 in series V=6 so parallel wiring would get you the hottest output. If they are still too cold, a few thoughts come to mind -
They are just a bit terrible They are designed for 24V systems (e.g. trucks)They are not able to draw the required current due to upstream restrictions (although this usually melts wires or blows fuses)
Which ones did you get? What were the technical specs?
