You can use either set of RCA outputs for the amplifier that you want to. Only difference in either of them is front, rear and sub outputs. If you are only powering a sub amp, then use the sub outputs, otherwise, the other two will work fine. You can still use the outputs from the radio itself to power four other speakers while using the RCA outputs.

well to give you a quick run down of wire colors: red: hook to an (fused) ignition wire. pos. (+) yellow: Goes to a fused constant wire (battery works) Black: is a ground (-) hook that to the chassis blue: Amp turn on output (+)... that goes to an amp the color pairs i.e. white, green, purple, gray are for the speakers, the (-) is the the one with the black stripe... what else would you like to know?
The amps are located inside the radio. Most in-dash receivers that provide for "pre-amp outputs" also called "low level outputs" do so by providing female RCA type jacks. These are often found at the end of a short (4 - 6 inch) cable and are usually color coded red & white or red & black (some receivers provide a yellow RCA jack for video in / out, too). To use these RCA audio jacks, you need to realize that one jack is for the left channel source and the other is for the right channel source for a stereo signal. You will have to connect a compatible plug and cable of enough length to extend to a remote amplifier's RCA input jacks. The vehicle's speakers would also need to be connected directly to the same amplifier's output terminals. Using the two audio (left and right) RCA jacks will only allow the radio to control balance of the left and right audio, no fader (front and rear) control is possible. To get fader control, you'd have to either have a radio with four RCA low level output jacks (front L & R *and* rear L & R), or use the radio's speaker (or high level output) wires and connect them to the amplifier's speaker (or high level) input terminals.
All unused receiver wires should be terminated in a wirenut or securely wrapped in electrical tape to prevent accidental contact with grounded metal or other wires behind the dash.
Do you have the remote turn on lead hooked up to solid blue wire from the back of the deck? Your amp shoild be hooked up to Bluw w/ white strip as the solid blue wire shuts off when the tuner is off, its used only for the power antenna.
I will assume that none of those wires are marked, thus leaving you with the cumbersome task of tracing each wire to its place of origin and properly marking them.
I will also assume that you have a standard hardware configuration whereas the in-dash head unit serves as an input selector and pre-amp for your aux.CD/DVD unit.
A possible shortcut would be to first identify the two power leads( one is a constant 12+ volts & one is a switched 12+ volts that is a remote power lead from the head unit) and the ground that was ran to the missing amp, mark and separate those from the group. Then with a test speaker trial and error those remaining signal (speaker) wires with the in-dash CD player on and loaded so as to find that units signal outputs (there may be more then one pair) You will need to identify left and right output signal pairs by adjusting the head units L & R control and marking those wires accordingly. Next with a pair of signal leads with output, temporarily connect them to all of the other unidentified signal pairs as to determine its speaker and marking them accordingly. At this point you should be able to make your left and right speaker connections.
Note: it will be wise to have a DC voltage tester to check for the missing amp power leads and signal polarity especially if you plan to install a new amp.
are you using RCA outputs(the round red and white plugs)? if you are then your amp is not turning on and if you are hooking up speakers to your RCA's (low level) then you will not hear any audio the signal is to low. would need to know more about how you checked the ic power?? one could verify an output ic by hooking up an amp since the RCA audio signal is picked off just before the output. if the low level works but the speakers do not then you have a bad output. anything else an o-scope would be handy.

blue and white wire on a pioneer is usually the power antenna wire, most people use it as the lead for power to turn on the amp that is installed, the amp should be hooked up to the RCA jacks on the back of the player to the input RCA jacks on the amp. then the outputs vary, some amps are bridgable which means that you can hook up one speaker to both output speakers this will almost double the watts to the speakers. you must know which side would be positive and which side negative to set it up like this. also important is it a two or four channel amp. this all matters. if you can provide more info I can assure you the best hookup possible for premium sound.
The sub outputs are simply lowpass filtered preamp outputs for use with a subwoofer amplifier. They supply a lowpass filtered signal for a subamp or 'powered subwoofer" like a bazooka tube. Test your "basstube" for 12 volt input power and make sure the "sub" setting on the radio is turned up too.
