Hello all, I bought this amp used for my son. It feeds two chambers and two lower WILDER BST BST BP360. Well the fact that it is really all electronic music (the boom boom as say the young) What power! The original version of this amp is the March 4 and March 6 of PHONIC. Only changing the faade. The photo in the magazine cover t sonomag (an old sonomag) If you sell an fates me know.
