Low Gains at amp


adreano17

Recommended Posts

Low gains at my amp. I have checked everything! New amp, new ground, new RCA, new LOC, new LOC with new RCA, amp bypass, still no more than about 2v at amp terminal at max gain. Only thing left to get now is a new radio or iPod integration. It started with only one channel giving me problems, now its all of them. Did my factory radio just take a shit? Please help, I'm ripping my fucking beard out...

and yes, I have adjusted the LOC gains as well. They are half way. Not trying to clip all at the LOC to begin with.

Sorry, I am rushing and has been a long day. Low voltage at amp speaker terminals despite gains being turned up. The max volts I get at the amp is only 2v

2v while doing what? Nothing is playing? While stuff is playing? More details.

Multiple dumbass moments in a day, please forgive me. Playing 1khz test tone on repeat at 3/4 volume on stock headunit. 4 channel amp. HPF on, as well as tried with FULL filter on. When DMM in AC volts, it only shows a max of 2v at the speaker terminals on the amplifier. Mind you, this is while the gain on the amp are near maximum. Thanks for the help in advance guys.

Are you 1000% sure your DMM isn't auto ranging, and you're mistaking 2V for 20v or something like that? Easy mistake to make if you're not very familiar with the equipment.

That seems plausible. But I don't think so. I am using the lowest AC voltage on the DMM. The only two options are 600 and 200. I am using 200.

Should I just replace my factory radio? Seems like the problem is arising before even getting to the factory amp. Bypassed or not, same characteristics.

i would...a good clean signal (with voltage ;-) is the only way, especially if you're putting all that nice equipment in.

if that's the issue...sounds like it hmmm
