stock sub blew so I purchased a Kicker CVT65 6.5" 1-OHM for my 02 RT/10, "everything else is stock at this point" hooked it up and sounds great only problem is when I raise volume level to 21-22 all the speakers including the sub woofer go silent, should I have purchase a 2, 3 or 4 OHM instead of the 1??? Is the 1 drawing too much power and causing it to silence??? Thanks for any insight.
