Hello michaelandta,

Check your filter settings on the front channels. It sounds like they may be set to "high pass" which would eliminate the bass frequencies. If you are using the amp to power normal speakers, it's usually best to set the filters for "full range". If the amp only has "low pass" and "high pass" settings, turn them both OFF.

Hope this helps.

Watkins woofers are not a normal dual voice coil woofer. They are designed to be used with a special crossover that when one coil starts rolling off due to rising impedance the other takes over to extend the bass frequencies lower. vauygorgxmaaaaaasuvork5cyii=
