I use these amps for years! I'm very happy! it works as well in that sub Broadband! I use 2 boxes DIGAM 7000 to 16 cm in 38 pavilions and a toboggan DIGAM 7000 8 cases for 38 inch mid-bass! Very stable at 2 ohms, generally I use them in heavy use for 48 hours non-stop! Finally, I use 1 to 4 heads DIGAM d1502 nexo 1000 and if all works very hard! I would definitely advice, good luck!
