Eclipse aluminum sub, what x-over frequency?

[verg 10+ year member]

I have a 8122 aluminum sub in a sealed box 1.25 cf. What should i do as far as setting my crossover frequency? I have a xtant x1001 so everything is by jumper so it is not as easy as turning a dial..... I listen mostly to rock 70% and 30 % rap....just looking for a nice clean thump .......

Just set it by ear, I'd suggest somewhere between 50hz and 85hz. We can't tell you exactly what frequency to tune to as it is vehicle/install/eqiupment/etc dependent. No way to give a definite answer over the net. Just whatever sounds best to your ear.
