According to the specs at this auction, they say this amp has a crossover of 40-120mhz. Does this mean it ignores anything below 40? If so, is there any way to defeat this? I'm curious about using this to power an SVS 20-39 with. Auction is here: http://cgi.ebay.com/aw-cgi/eBayISAPI...tem=1275321253 Thanks guys.
