Right now I have an 18" sub with a Crown XLS 2500 amp off of one of my sub preouts. And 4 DIYSG MBM's on the other sub preout using a Crown XLS 1002 amp. Now can I run a y splitter off of one of the sub preouts and a 1000watt RMS plate amp to a 12 inch subwoofer without messing anything up? Thanks for the help guys!
