i have 2 12" subs in my car & i have it wired to a stock radio. i have a converter that takes the speaker line & makes it into RCA line for the amp. but the speaker line that i connected off of is not the line to the stock sub, its just one of the door speakers. So out of my subs im getting the full signal, bass, vocals, ect... Can i damage my subs by having it this way? im just trying to save some time & energy if i dont have to re-wire it.
