This amp cabinet is going to be huge. I am looking at putting the batteries on top of each other to go up rather than sideways. At the moment, roughly speaking, there is the choice of having them side by side:
OD = 446mm W x 335mm D x 100mm H
or having them on top of each other:
OD = 314mm W x 335mm D x 175mm H
I think the lower (higher) version will look good and take up a much smaller footprint. But what size heatsinks will fit and where to put them?
