[QUOTE="Lusso5, post: 311709, member: 549868"] My experience as well. More specifically: 1st order -6dB/octave, 2nd order -12dB/octave, 3rd order -18dB/octave. The lower order the more frequencies above cut-off pass through. The HU x-over is likely a lower-order than the amp. Nice thing about using the HU x-over is you have sub bass-boost control right at the deck. If you dont have a control from your amp up front, I would recommend using your HU x-over (so you can have sub bass-boost control) and using your amp x-over, as well, at a slightly higher point than the HU setting.
