Htc one m8 beat audio or speaker boost? topic

Hi, i wanted to volume up my m8's speakers, i have Viper rom, and V4A installed, but i noticed that Htc One m7 is better on speakers than M8, because of IntenseBLAST mod provided to m7, is there a way to volume up my speakers? There must be a way, this intense blast mod doesnt work for m8 cuz M8 doesnt have Beats audio, can someone help here?

Thanks in advance.
