oh and by the way i fixed my problem. i have it set to 2v - 8v. i just re-adjusted my amp settings. im done for now got new batt in hatch voltmeters installed and voltage is where i want it be.... and this may sound funny but this amp is louder then my saz was. it may be that my voltage is better but im just saying. the sound pressure and the amount of air being moved is a bit more.
