You can download a the manual from Crutchfield. A complete wiring diagram with color codes is on page 41.

The battery needs to be sufficiently charged to at least 8V to power on the radio.
Check the battery is fully charged.
A better option is to wire it directly to a battery charger + and -.
But you have the setup correct.
Yellow and red to + and Black to - in order to bench test it.

One thing to remember about most radios, the RCA pre amp circuit will still work even if the mosfet power amp inside the radio does not. The best way to know if the amp inside the radio works is to use one matching color pair coming off the radio to wire up a random speaker right to the radio. You can use just about any old random 4 ohm speaker that is laying around to check it. The best solution if the amp inside the radio is blown is to replace the radio or amp the pre amp outputs with a small 4 channel amp. Oh, by the way. What vehicle are you connecting this into? And does the vehicle say Bose, Infinity, or ect sound or Premium sound? These usually denote a factory amplifyer already onboard and requires special connections to get the signal to these amps to then be delivered to the speakers.

The black wire will be connected to the body or engine of the van and the red or positive wire is connected to your starter motor.
You can also use a 12 volt battery light to check the negative or positive wires.
You take the 12 volt battery light and place the negative black wire clip to an earth on the vehicle, then when you touch the tip of the 12 volt battery light onto a positive wire the light will light up.
Then you will know which wires are negative or positive sometimes the key has to be on for some wires to work.

* special note * do not use any more than 1.5 v as it may damage the speaker coilAs we know, batteries are marked positive, negative, or both ... we will use this to our advantage when hooking up the battery to our speaker.
To start the process, temporarily attach a short piece of wire to each terminal of the speaker (be sure to either use wire that is marked, or wire of differing colours to help determine which terminal is which).
Once you have connected the wire to your speaker, proceed to briefly touch the free ends of the wire to the battery terminals (as shown below). In some cases, extended contact with the battery has caused cancer of the voice coil (ie. blown speaker)
If the speaker moves OUT when the battery is first connected, the battery is connected in proper alignment. Be sure to take note of which wire is connected to the positive terminal of the battery as this is your speaker's positive terminal.
