Help with a Kenwood DVD/NAV

[MikeyV]

I'm trying to hook up a 4 ch amp and subs to a Kenwood DNX5120. it's a Doub DIN DVD/NAV. I'm stuck because I'm not sure how to run the preamps. There are 3 sets, front, rear/sub, and audio/video out. The unit has sub controls built in so if I use the rear/sub out for anything but the sub, I'll be controlling everything hooked to those outs. If I split the rear/sub, I'll be controlling the rears and subs from the head unit. My only option splitting the rear/sub out is to leave the head unit sub setting so the rear speakers sound good and control the sub from the amp. if i split the front I don't think I'll get the stereo sound and I'll lose fader control and who knows what else. Anyone have any ideas? You would think a head unit like this would have dedicated sub outs. That's what I get for being cheap and buying used!

If you want to use the deck to control the sub then split the front. The only thing u will lose is the front to rear fade. Stereo is right to left so no problem there. If you split the rear you are correct in saying the sub will have to be controlled at the amp. It is odd that it doesn't have a dedicated sub out. How are you hooking up the speakers to the amp, which channels running what? You can use the deck amp for the rears, if they're behind the seat they're just fill sound anyway. Use 2 channels for the front and bridge the other 2 for the sub. In that config. the fader and all controls should work.

Just went through the manual online and if you want the use of the rear zone volume it sounds like you will have to use the deck to power the rears and set the preout to sub.
