The voice coil in the big speaker could have been damaged if driven to loud. See if the burnt smell is strongest near the center of the big speaker. If the voice coil is fried, you may be able to still find a replacement as there is a part number for the voice coil (V/C Assy, EON-G2220-27005-00) and the cone (EONG2
Cone Repl. C2REON15P-2)
Yea, you blew the voice coil. Pressing on the cone where you are is hitting the spot that is making the coil connect again. Just like a shorted wire. Sometimes you can bend it and get a connection. You are gonna have to replace the sub.

There are a couple of reasons why this might have happened. Subwoofers are finicky. I always recommend to my clients that you don't apply full power to your sub until you have had one week of playing it at low volume. This helps to condition the voice coil. When at full power the voice coils heat up rapidly. To go from cold to heat fast will warp the coil. The bad news is that this would fall under the "abuse" category for refunds. Then again, you might get lucky with a return unless you bought it from an individual. The other thing might be how it was wired. If your amp is 4 ohm stable and you wired to a 2 ohm load, it may have shorted something. But you would think that would be the amp. Not sure this answered the question, but just a few ideas to think about.
If both subs are dual voice coil, you can wire one voice coil to other voice coil on each sub. Do this by running the ground of each coil to the ground of the other coil. Do the same for the positive. After doing this on both subs, you should have one ground and one positive per sub. Hook one up to the left channel of amp and one up to the right....This should work for you. If your amp plays for a while then goes into protection mode, then it cannot handle the ohm load.
the voice coils are probably fried. you may want to check your amps to see if they are putting out dc voltage. you may be abel to find a place that can fix the subs. otherwise you will need to replace them.
The "DCER" error is caused by one of the speaker wires shorted or grounded or a shorted voice coil. Remove the speaker wiring one at a time to determine which one is causing the error, then repair or replace the defective part.
You may need to press the reset button (small recessed button to the lower right of the volume control) after the problem is corrected.
You have a shorted speaker or a speaker with a bad voice coil. This has been confirmed by the fact that the audio amplifier is shutting down (protection) but the unit stays powered on. The speakers will play for a few seconds or maybe even longer at lower volume, but any length or time or an increase in volume will immediateley shut off sound. This is due to the fact that a shorted speaker wire/connection will ground out or short to one another. If you have checked all connections behind the radio AND at the speakers and found no problems, then it is a voice coil on the speaker. A shorted voice coil will work until the speaker cone moves causing the short or until enough power passes through the voice coil's short to turn off the radio. Solution: 1. You can use a voltmeter set to check continuity to test for a speaker short. Disconnect all speakers from the radio and connect one side of your meter to ground and the other to the speaker lead. An audible "beep" will confirm a short. 2. The other method would be to disconnect all speakers and re-connect them one by one until the radio's sound output shuts off again. This will be your shorted speaker. I hope this information was helpful.
Make sure all speakers that are hooked up sound ok. If any of them sound lower then the others or sound distorted you may have a speaker with a partially shorted voice coil. If speaker or speakers pop when power is first applied you may have a grounded speaker that should not be grounded. Each speaker wire rides on 6vdc and if any speaker sees a ground you will have 6v across voice coil which would explain any popping noise when first turned on and radio may play for awhile then overheat. be sure speakers are 4 ohm min per ch otherwise amp will run to hot.
