I have a Hifonics Txi 1508D amp (http://www.onlinecarstereo.com/CarAudio/ProductDetail.aspx?ProductID=18418) and the hifonics logo is lighting up but neither the power light or the protect light is not coming on and i cant get my subs to work. Ive double checked all the wiring and fuses and cant figure out wat the problem is. Any help would be appreciated..thanks
