Your question still makes no sense, posting it in a new thread wont help.

 

I think he is asking if there is away he can use the factory amp, im guessing for the front and rear speakers, and still use his RCA outputs for his subwoofer, and if the item he posted would be the piece that he would use to do that.

 

check out page 2 of my sig. you should use the speaker level outputs of your deck and bypass the factory amp(which is easy). You can use the factory subs then if you want but if you are putting in a set you will not want the factory set playing........

 

o.k. I want to put a new headunit in my car and still have the factory door speakers and amp for the mach 460. But i also want to add a amp and sub woofer to the exsiting system.

 

simply buy a rca y-splitter then.
