phoenix gold xennon 600. i adjusted the input voltage dial on the amp and it seems to me like the lower freqencies 40 n down are reduced by a db or 2??? in fact sq over all is less smooth? sub output voltage from headunit is 2 v,set amp input at 2 v and its less likeable to me than when set at .2 v? obviosly ill play with the setting over the next........10 years!!!!!!!!!! but i was curious if anyone has any experience with this phenomana?
