Not sure if it is my amp or my cars electrical or what but my sub will be playing and then all the sudden it will get this crazy boost in sound usually caused when i turn up my stereo to its maximum listening volume which is wierd...it will not play loud during the day when it is hot in my car but at night it will wang harder than ever i will have to turn my sub settings to -5...anyone have any idea what might be happening??

Thanks

Sounds carries further in cooler air. There is less ambient noise at night. For these two reasons, your stereo will always sound louder at night than during the heat of the day.

Now, if you are describing sudden and rapid changes in volume, like it changes audibly as you listen to it, that indicates a problem, and a weird one at that. Id probably start by looking at my signal chain first in that case.

yea option B is whats happening...its reallly wierd...im thinkin it might have something to do with my remote wire but i have no tools to figure out if thats actually it...also just today my radio started turning on and off on and off on and off on and off and then would randomly stop and work again...idk wtf is going on its worrying me

but yea its like a rrreeeally big spike in volume like from not that loud to what it supposed to sound like

Sounds more and more like voltage issues. Low system voltage would start making electronic equipment act... weird. Are you severely taxing your charging system?
Its not likely a remote wire. The rem wire merely turns the amp on or off, it would not affect output beyond that. Now if the amp was randomly shutting off, yeah Id say check the rem for a loose connection.

If voltage isn't the problem, start isolating pieces of the system by bypassing them, until the problem goes away. This will tell you which piece of equipment is the culprit. For example, find a boombox with RCA outputs, and hook it up to your system, bypassing the h/u, and see if the problem stops. If not, move on to the RCA cable, running a temporary one across your seats to bypass the permanentn one, and see if the problem stops. etc etc etc.

Hope that helps.

Ah multiple batts.... new information. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif//content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif How you have the batts wired together... relay? Isolator? Direct? Unless you are running an isolator, only one batt should never be dead by itself.

wired directly no isolator...my voltage doesnt drop at all tho when im playin music loud or at idle although sometimes it idles right under 14V
