[QUOTE="Beatin', post: 8065406, member: 646085"] ....who got his amp/subs installed to the factory head unit. Problem is, his amp seems to only play like 60hz and under. It won't play higher notes for some odd reason. There is no HPF, only LPF-FULL. We put it on full and lpf with the lpf knob on the highest it can go to, 500hz, so the amp will play everything under 500hz. We tried tuning with a 50hz 0db tone and guess what happened? He turned the gain all the way up and still we couldn't get a reading on the DMM. We had to use the bass boost knob to get a reading.
