Mark, not only won't it be night and day, it probably won't even be midnight and 12:01AM. More power, whether by way of separates or otherwise, won't necessarily make the slightest difference in bass or anything else audible. If you had say 200 watts per channel instead of 100 that would give you 3db more headroom. If your set up distorted audibly at say 115db peaks, you'd now be able to do 118db. Unless your 2802 is audibly distorting(unlikely) relax and spend your money on something that makes a difference.
