since 100 and 110 are so close i'd go with something that is 100x4.

personally i have a ppi4125 (125x4) running some 6.5" crystal components and the rear channels are bridged running 2 12" subs. i'd rather have clean power than not enough power. jl makes a 450/4. will have like 115x4 or something. remember you can always keep your gains real low to prevent pushing too much wattage to your speakers.
