If the amps have power running to them, have u checked if you switched them on? Seems like the only think you might have missed, be it mundane.

Some decks have a dedicated subwoofer out. Sometimes, this can be turned on and off in the menu settings. If you have a subwoofer out, have you checked all of the menu options for this? You may have bad subs, a bad amp, or a bad deck. You can easily eliminate each by some quick testing. 1. Test the subs by REMOVING the speaker wire from the output terminal on the amp. You can touch the positive wire to the power terminal and/or a positive lead on a battery, and the negative to the negative terminal on the amp and/or the negative on the same battery. Tap them quickly. If the subs pop, they work. 2. If you have a buddy with an amp in his/her trunk, have them back up to your rear bumper, or wherever the closest acces is to your amp. Using an extra length of RCA cables and a pair of barrel connectors extend the RCA cables from the RCA's in your car, to the inputs on your friend's amp. Turn the radio up. If the subs and amp in your friends trunk work, your radio and signal cables are fine. 3. Keep this same buddy handy. Use the RCA cable extention from the other person's RCA's in their car, and plug them into your amp. If the amp and subs in your car work, you know your amp is fine. There are more troubeshooting options you can go through, but these will likely be the fastest and easiest. Good luck!
