Hi guys Ok I just bought a sony sa-wm40 to go with my sony mini system, but when i hooked it up with the rca cable, there was hardly any bass!! ( I turned the sub level all the way up, i set my speakers to small, and db level to +6 and there was little improvement). So i was just wondering if connecting the sub directly from my dvd player ( with DD decoder) will help in any way??....also will it cause any problems??
