I've installed and upgraded a few systems in the last couple years as just little hobbies. My last amp upgrade was to a Kenwood Excelon KAC-8105D 1000 Watt Mono to power my 2 10" Kicker CVR in a ported box, operated from the Alpine XDA-305. The amp is very efficient for $100 when i purchased mine a year ago. Definitely money well spent. The amp imo, is small and nice to look at. It you have blue ambient lighting in your vehicle then I'd recommend showing this amp off as part of your ambiance. It has never over heated on me even in the record breaking heat of Nebraska weather (109 degrees F outside my black 05+ GP GT). My levels and gain are even dipped a little low just in case, I know I could blow my subs with this amp (especially if I installed a capacitor to my system). Check their equipment out, other wise stay with Rockford, Alpine, Kicker, JL for your popular brands. Maybe even look into Soundstorm, not as popular but I trust their quality.
