Channel Subwoofer

Is it possible to connect 4 channel amp to 1 subwoofer?

I have a 2000 watt 12" sub and a 2800 watt 4 channel amp. Is it possible to use 3 or 4 of the channels to power the sub? For example bridge the amp to 2 channels and connect both to the subwoofer?

Thanks!

You can do this if it's a dual voice coil sub, and the voice coils aren't lower impedance than your amplifier can handle in bridged mode. For example, most bridgeable amplifiers require a load impedance of 4 ohms or higher, so if you have a dual 2-ohm sub, it won't work. If you do have the right impedance and coil configuration, then you can bridge the 4-channel amp down to two channels, and connect one channel to each voice coil.

The power numbers you're quoting are "peak" power ratings, which are essentially meaningless. When matching an amp to a sub, you need to look at the RMS ratings, not the peak ratings.
