With regards on using the filters on your amp or HU. You neither use one of them since your speakers comes with passive filters already. Just turn off the HPF on the HU and set the the filters of the amp to off or all pass. If the amplifier does not come with the option of setting the filters to off or all pass, leave the settings to HPF.
