My head unit worked fine untill i plugged into the rca jacks for my subwoofers. now all the buttons work and the head unit shows its playing noise but nothing comes out. Even with the rca jacks taken back out there is still no sound. Did i blow a fuse or short something out?

Your description is not very clear but my guess is that the output from the RCA connector on the head unit (receiver) is low level and intended to be connected to an amplifier input. Apparently the 3.5 mm "jack" (plug) connects something to the RCA input of the amp and that works.
Make sure the antennae input is plugged into the back of the head unit. There should be a lead behind the dash coming from the car for the antennae. This will plug straight into the back of the head unit to receive radio signals.
first of all the rca jacks in the back of your radio are for plugging in an amp, not your mp3 player. there should be an auxiliary jack(looks like a headphones jack) in the front of the head unit. if there is no auxiliary jack in the front then you will have to go buy a new head unit with an auxiliary jack.
first check that the subwoofer function on the actual head unit is turned up,second check that the gain on the amp is at bout half way then check that it is on a lp (low pass setting)
then check that the boost on the amp is turned up.
please leave feedback.
The adapter cable will convert the changer port on your head unit into an AUX input with dual RCA jacks. Once connected, the head unit will detect the cable and allow it to be another source (i.e. radio, cd, aux).
To connect your iPod to the adapter cable, use any iPod cable or dock that outputs to male RCA plugs.
There is no power from the rca jacks. Option 1; connect the speaker wires directly. Any aftermarket auto manual (Hayes, Clymer) with wiring schematics will let you know what wire is what in the dash. Option 2; RCA jacks output to an amplifier. There is no power coming from the RCA jacks. They have to be used with the amp. If you chose to use the normal speaker wires, be aware that these radios do not like stock speakers or wire. If you take the time and money to replace all of it, the head unit will last much longer. If you choose to use an amplifier, it will burn out fast unless you replace the speakers and wires immediately.
As far as iPod connections - they will work with a regular iPod and an iPod Nano. You have two options depending on how much you want to spend and how much convenience you want.
Option 1 - Use a Pioneer CD-IB100 adapter. This will plug into the docking port on the bottom of the IPod, charge it, offer control and song information on the head unit. You need to use this one and not the newer CD-I200 cable because your head unit is not compatible with the newer piece.
Option 2 - Use a Pioneer CD-RB10 adapter and a 3.5mm to RCA cable that will plug into the headphone jack of the iPod. You will only get audio input to the head unit but this option is somewhat cheaper.
As far as the clock settings - hold the 'source' button to shut the unit off(key still has to be on). Push the 'function' button until options appear - you can switch between options by repeatedly pushing the 'function' button and adjust settings by using the up/down/left/right arrows.
Your problem stems from the fact that the CDA-7892 is not equipped with an RCA aux-input jack. If you're plugged into RCA connectors at the back of the head unit, they're outputs, not inputs. The sound you hear is just feeding back through the outputs and into the head unit's amplifier.
If you want to play your iPod through this head unit, you need to purchase either the auxiliary input adapter (KCA-121B) or iPod adapter (KCA-420i).
