Seeing as I find myself being an Orion fanboy of late but I’m going to recommend an XTR again, specifically XTR2500.1DZ rated at 1600wrms @12.6v .5%THD and they are reliably underrated from what I’ve seen I think they put out about 1800 @14.4v 1% THD certified but you might want to watch BigDWiz’s dyno video of the amp they are monsters for the money.
