I am thinking about redoing my mids and highs with a total of 8 Selenium 6W4P 6" Woofers 2 in the front doors, 2 in some kick panels, 2 in the middle section and 2 in the rear. Also thinking about a total of 8 Selenium St200 supertweeters, 3 on each side of my front and 2 in the rear. I will be running them off a Audio System Twister F4-600 at 2ohm with the specs below.
4 x 145W RMS @ 4 Ohm
4 x 230W RMS @ 2 Ohm
2 x 460W RMS @ 4 Ohm Bridged Mono
