Just a suggestion....Take that EV driver out of those subs and replace the jacks on the back to Speakon...throw the crossover in the air and shoot it with a shotgun and then pop some Peavey Low Rider 18's in there...never look back. THOSE subs will do wonders as a cheap flip. Be sure to place them on horse stall mat to prevent slippage and give em power.
They do have Peavey low riders in them.
I also picked up a box full of XLR plugs, panel mounts etc at a yard sale cheap and use them for speaker plugs on all my stuff. I left the crossover in for the occasional full range link up to my tops I power them with the IPR 3000 DSP, sound REALLY nice
