yes you can do that but how are you going to set the amps the exsactly the same and don't think that if you turn the amps gains all the way up works because evary amp is different most of the time the amps will fire a diferent load of power to each sub so you are going to need a volt meter the shows the voltage in ac volts to set the gains the right way just set the gains at the desierd voltage in your case you are going to nees to set the amps at about 32 ac volts each then hook the subs up and test it agin and see what the drop in voltage is and tturn the gains back up to 32 with the subs coneted and will it is playing 50 hrz is a good frequency to set your amps at. o also make sure each sub has its own chamber do not share the chambers or after a will you most surely fry one or all of them if there are not in there own chamber if you plan on putting one amp on each sub.
