I want to put some subwoofers into my GT-S but I'm not sure what is needed. I know you need an Amplifier and the subwoofers themselves, but Do I need to get a new deck to run them. I currenlty have the factory 1 disk deck. Sorry bout the newb questions.
no. they make low level line converters, you just hook them into the speaker wire and it has an RCA out....and that goes to the AMP. SOme of the better ones require power, so that gets hooked to a 12 volt source. i use my cig lighter as my remote...it goes from the lighter to a toggle switch (so the amp doesnt always have to be on) and from the switch it goes to the converter then the amp.
