i have a pioneer gm-5000t amp, a pioneer 200watt cd player and 2 bazooka 12s. i sold a system just like this then i bout another one only thing that is different is the cd player. i had a dual 220watt cd player and had no problem. now my subs wont come on unless i turn it up alot then they will come on but when i change songs i got to turn it down then back up again to get them to come on does anyone know what could be the problem
