Gold Member Username: StnorrisIA US Post Number: 1229 Registered: Apr-06 | i was trying to set my gain on my amp. my amp is 1000rms @ 2 ohms. i was gunna set hu volume to 3/4. then play a 50 hz test tone, then check the pos and neg on amp with a dmm. chadlee told me the digital readout should say around 47.7. but my question is what do i set the knob too on the dmm? it says like ac 10, ac 25, ac 50, ac 100, on the ones ive seen. so what do i set the knob too, to get the right readout? |

Gold Member Username: StnorrisIA US Post Number: 1232 Registered: Apr-06 | if the numbers actually meant voltage that wouldnt make any sense. if you set ur HU to 10, ur amp will produce more power/make sub louder faster at 2v, than 4v. if those numbers mean voltage, that amp gets louder as you turn from 0 towards 11. that would be backwards. http://www.bcae1.com/gaincon2.htm |
