OK I just got my lancer and I have the rockford fosgate sound package as most of us do and also the Navigation with hard drive. I do not want to change or remove the door speakers or anything whatsoever. I do however want to add one or even two 15" Alpine Type R's. I have all the wiring, amps, subs, everything I need to do so as I just took my entire system out of my 2005 Avalanche that was properly hooked up and working. Now my question is since I have the navigation is it possible to hook up one or even both 15"s running off the navigation. I figure it has to be able to be done since there is already a 10" rockford sub already running off of it. I do not want to install a headunit even though I have two extra, I want to keep the navigation and hard drive but also have my 15"s hooked up. I also am aware I will not be able to adjust the settings on navigation as I would be able to on a headunit and also am fine with that. Now keep in mind that even if I can only get one installed that is fine by me. I also do not mind if I lose the factory 10" sub in order to have my 15" sub. Now I wouldnt mind keeping the 10" also but I would/want to sacrifice it for the 15" if I have to. Please give me any information you know or tips to help. Thanks for any and all responses.

 

anyone please?

 

Use a line-out convertor to supply you the RCA connections for the amp. Thats all you need. Everything else is self explained.

 

thank you very much

 

^ are you going to connect a RCA converter off the Rockford sub wires that is connected to the stock amp??? if you are there is no sound quality in that at all.
You will need to some how get sub signals comming from off the cd player not sub signals off the amplifier. I dont know how yet but i would like to know how to het these signals
