I am going to be switching to a behringer inuke 1000dsp to power my new sub project. Question is on hookup. My current receiver has a rca sub output only. My sub has rca input only. The behringer does not have this type hookup. Suggestions on hookups cables. Also i believe there is a fan mod for this but can find the link for this. If some know were it is or know whats needed please let me know. Thanks.
