What SQ setup? So far all you have described is the sub which if the rest is done well isn't even really hardly necessary at all in an SQ setup. :bigclap: I have the fi ssd powered by an audioque 1200d the in the front i have ES-620Z - CDT Audio EuroSport 6.5" 2-Way Component Speakers power right now by a rockford 360.2. The amp on the doors is going to be changed but waiting on zed's new line to be released and maybe even the sub amp.
