My uncle has two 12" Boss Audio AVA-W126 dual 6 ohm voice coil subs. He doesnt know anything about them and he wants an amp.. If im right, he'll either need somthing that is stable at 6 ohms or at 1.5 ohms. Does anyone know what amp will be good for these subs? they're 350W RMS, 700W max. Does anyone have these or have heard them, let me know
