I don't personally have an UDP but the ones manufactured for our cars get most of their power gains from being lighter, not necessarily smaller than the factory one. It is a little smaller but not so much as UDPs for other cars. Depending on your system it may be a factor but I doubt it. If your lights all ready dim when the system hits then they will continue to, if they don't, I don't think they will start to, unless your over 300 watts. I'm no expert on this so search, you might also want to post in the electronics section of these forums. Good luck.
