bumonskateboard6 Posted July 7, 2009 Report Share Posted July 7, 2009 In my car at full tilt I sometimes have bad voltage drop down to the low 11's and as driving home tonight it seemed not as loud as normal so when I got home I opened the trunk to look at my subs and it seems like one sub is moving twice as much as the other one. Does anyone think that the drop in voltage could have damaged one of the subs because the amp is completely fine not hot, no protect, no fuses popped...

Low voltage doesn't blow amps. That's a myth. A router that does the sub holes makes rounded edges also? Link to comment Share on other sites More sharing options...
EricM9104 Posted July 7, 2009 Report Share Posted July 7, 2009 When your voltage drops that much, you're gonna be clipping the shit out of everything. So yes, you more than likely damaged the sub.

HHR Ed Posted July 7, 2009 Report Share Posted July 7, 2009 check wiring to the sub. Voltage drop will have nothing to do with the sub itself, but if it dropped below 11, you are in risk of blowing your amp.

bumonskateboard6 Posted July 7, 2009 Author Report Share Posted July 7, 2009 check wiring to the sub.Voltage drop will have nothing to do with the sub itself, but if it dropped below 11, you are in risk of blowing your amp. I pulled the sub out of the box and it's still wired right and all the terminals are wired and in place too. It seems just like one of the coils on the sub isn't working... I know I need a new alternator too but the amp has been doing fine with no damage.

Kian Posted July 8, 2009 Report Share Posted July 8, 2009 take the sub out again and stick a dmm in the terminals and see what each coil is reading more then likly your gonna see one coil's numbers all wacky.

Yeah I have it disconnected right now so it doesn't cause more damage to anything and conveniently last week my DMM broke so the replacement for that's on the way too.

ALPINE408 Posted July 10, 2009 Report Share Posted July 10, 2009 do you have a 9 volt... 12volt or 18volt drill batt???? if you do run a wire to the pos and then anouther one to the neg of one coil then tap the prongs on the drill batt the sub should pop out or suck in depending on polarity (sp) then do the the other coil (if there dual coils) if one side dont do anything you got a bad coil Quote Have you ever had your woofers blown?
