Are the amps mono or 2 channel? if they're mono i guess you'd want to wire each sub +to+ and -to- which will bring each down to 2 ohms. that should bring a bit more out of the amp and "maybe" not the full 1,000 watts stated power depending on wether it's 1 ohm stable. if this IS the case then each sub should be getting anywhere from 500-750 wtts rms each. if they are 2 channel then they should still be able to run at 2ohm mon if you bridge the amp and keep the wiring of the sub the same. hope this helps and good luck!!
The above mentioned wiring will be good only if the subs are dual 4 ohm coils, if they are dual 2's then the wiring will change slightly.//content.invisioncic.com/y282845/emoticons/crazy.gif.c13912c32de98515d3142759a824dae7.gif
