I dont see whats wrong with it. The 4125 is for speakers. 10Hz to 1.2Khz is more than enough. Your subs should pick up around 60Hz and down. From 60Hz and up to 1.2Khz. I guess its an issue if you want to run active and cross your speakers over higher, but who goes active at the amp crossovers anyways?

yeah true do i have to have all four channels at full for my crossovers on my hu to work fully

Channels 1-2 full/or x-over

Channels 3-4 full/or x-over

if your headunit let you use x-over pionts & slopes then use the headunit.

yes swicth the amp to Full Range then.
