I saw this question come up in another post, but didnt see an answer.

Ive got a 2 channel Kicker amp, and 10" sub that I would like to put to use. Can I splice these into the factory RF setup somehow? Or would I need to gut everything and go all aftermarket?

Thanks!!

well if there is no other way you can always use a line converter off the back speaker signal

i have 2 10" kicker subs and a 2 channel kicker amp and its off of the factory stereo i got it installed at al and eds they used a high/low unit to be able to use rca's for the amp

Like other's mentioned, you will have to use an LOC (Line output converter). I assume the RF system uses an external amp. If this is the case then I would tap off before the amp.
