if the gold speaker cap make it like "mute" try the telos platinum speaker cap. sometime its try and error as diferrent system different requirement. also try the rca cap together with the speaker cap. also one thing to mention, when trying out the telos gigs like caps and cable. a piece of advise is "back to the basic" in which take out all the other tweaking giggs you have in your system then add telos giggs one by one. you willl definitely see a vast improvement interm of sound.
