I just installed a Pioneer F700 in my stang replacing my shaker 500> i just have a question in regards to the rca's. Well I know the harness has a red and white rca lead..the white for the front subs and the red for the shaker 1000 trunk subs. Well I have seen how some guys use a Y adapter to hook the singke white rca to the dual lead, but what i did was just hooked up red to red and white to white..I know the red is not doing ne thing for me, but I was wondering if it was actually hurting my sytem in terms of performance and if hooking up a Y cable would be improving performance. Sorry if
