Matching dual subs with only one sub preout

[Swartmorne]

Need some advice please. I have a denon x2400h avr, and this is where my problem lie. As far as i know, this unit does have 2 subs out but are bridged, so actually only one sub out. I have two subwoofers. How do i match these woofers?. Is there a product other than a mini dsp (rare comodity) that can be bought with a budget in mind?.
