it is quite a craftsman and audiophile.. yeah, i guess it wouldnt hurt, i just slapped in a bass tone and played in incriments from 40-55hz and layed the front seat all the way back.. didnt fool any with the amp gains and had my hu sub on -10 as well as all setting except front-rear speaker adjustments.. i also developed a ground loop hum right after i metered.. i gotta fix that
