Mach radio in my Explorer

My radio in my 98 Explorer recently died and i installed the Mach radio (CD-6) from my 02 GT in it's place. It went in very easy but i'm left with a small problem. I only have mid's and highs. Is there anything i can do to get a low frequency to my speakers? Any info is appreciated.
 
Eh, these systems werent really designed to work together... Without spending more money than a nice aftermarket unit costs, the short answer is, you're stuck without bass. Unfortunatley the crossover is built into that head unit and there is no easy way to turn it off...
