The freq knob is the frequency the output is lowpassed or highpassed at, going to the speakers. If it is strictly a sub amp, it will be low pass only, so just set the frequency where you want it. In that case, the EQ might be bass boost.</p> <p>&nbsp;</p><div style="clear:both;"></div>http://community.crutchfield.com/forums/thread/64189.aspxWed, 24 Jun 2009 00:57:21 GMTbd5cdc59-8905-44ac-b6bd-800f81497726:64189cfhmadman0http://community.crutchfield.com/forums/thread/64189.aspxhttp://community.crutchfield.com/forums/commentrss.aspx?SectionID=17&PostID=64189<p>I have a 12&quot;&nbsp;MTX Jackhammer JH5512-04 with an MTX Thunder 342 2 channel amp.&nbsp; I have it bridged&nbsp;at 340w at 4ohms.&nbsp; The amp has&nbsp;L and R gain, EQ and Frequency knobs.&nbsp; I cant find the specs for the amp online anywhere.&nbsp; Im not sure what the difference between the EQ and Frequency knobs is.&nbsp; None of the knobs have any kind of range on them either.&nbsp; Just looking for possible suggestions.
