Thinking about it.....if these were in line, they could actually go anywhere in the duct which will give a bit more flexability.
The only issue is the noise....blowers are usually not the quietest things in the world!!
Yeah, I though about the noise too, but if you mount them before the core and maybe wrap them in insulation they might not be too bad. The factory heater in my boat is louder than the blowers.
