I'm new to this board, like to watch what people say and learn but not post much. However, I'm having a problem with my system and want some advice. I have Pioneer 4X6's in the dash, 6X9's in the pillars, which are all ran off my jensen cd player right now. I also have 2 12 inch pioneers run off a kicker 250 watt amp which Yes, I am going to upgrade eventually. I have read about these "bass blockers" but it is all confusing. The 4X6's and the 6X9's break up at high volume/bass. I want to block like 80% of the bass seeing as how the subs take care of that. Can you please give me any advice how to setup. I think I'm going to go with a capacitator and try to block out the 4x6's and 6x9's any advice? I'll have pictures of the system tommorrow.
