Hi,

I need some help on installing an additional amp and my first sub in my car.

I currently have a Kenwood KDC-3025 single CD player deck (i know it's $hit, but that what i was able to afford at that time) with a kenwood amplifier. (don't know the model) At the moment, my deck is directly hooked up to the amp and connected to all 4 speakers. The deck has 2 sets of RCA ports (FRONT 2xPhono, REAR 2xPhono) that is connected directly to the AMP.

My friend gave me his old RF AMP and RF SUB a few days ago. How am i suppose to install the RF AMP + SUB w/o disconnecting everything else that was previously installed? The deck doesn't have the extra RCA output for the sub functionality.

Please help.

Thanks!
