Sid420 Posted December 27, 2011 Report Share Posted December 27, 2011 Okay. So I have been noticing that my subwoofers will start out quite and then all of a sudden while I am driving they will get a lot louder? Why is this? I use to think it was because my battery wasn't warmed up but that's not it because it takes like ten minutes and my car gets warm in like 2 minutes. Hope you can help.

99fullsizechevy Posted December 27, 2011 Report Share Posted December 27, 2011 Not nearly enough info... How's your volts? What are you running equipment wise, kind of car? Quote Laying frame soon.. System has to wait Link to comment Share on other sites More sharing options...
Quiet Posted December 27, 2011 Report Share Posted December 27, 2011 a couple things come to mind your alt kicks in and gives a couple volts more now and then you have a loose power terminal you have a bad RCA pair where one goes in and out I'm sure there's more to look at, someone else will chime in I'm sure.

Sid420 Posted December 27, 2011 Author Report Share Posted December 27, 2011 I am only running 400 watts less than that even. And it's a ford contour 1998 Quote Link to comment Share on other sites More sharing options...
Quiet Posted December 27, 2011 Report Share Posted December 27, 2011 Any amplifier with an unregulated power supply (which is most amps) will give more to your speakers if they're getting more voltage. Watch your voltmeter (you have a voltmeter, right?) and see if there's a correlation with it and the random volume bump. If not, then take a look at the other things I said.

Sid420 Posted December 27, 2011 Author Report Share Posted December 27, 2011 I have a volt meter but i have it un hooked. I will hook it up tomorrow and check it out. And no it. Once it gets loud it stays loud. But until then it is quiet. Quote Link to comment Share on other sites More sharing options...
