ZachG Posted May 23, 2012 Report Posted May 23, 2012 I know there is a lot of diffrent opinions about this matter but if you under power a subwoofer in a sealed box could it ruin the subwoofer? As in running 150-200rms to a 750rms dvc subwoofer? 1998 Pontiac grand prix gtp supercharged2 12" Obsidain Audio V.1 on a 2011 zx1500.1 at 2 ohms. 20ft of Knuconceptz CCA 0 Guage. 2nd Battery is a Shurken BT-120. Box is 3.5cu tuned at 31.8hz sealed off from the trunk. 14sqft of Dynamat on the Rear deck top & bottom. Soon to be more for doors/roof.

MrSkippyJ Posted May 24, 2012 Report Posted May 24, 2012 If under powering a subwoofer can hurt it, then every time you don't play you stuff at full tilt it could blow.

Guest Posted May 24, 2012 Report Posted May 24, 2012 If under powering a subwoofer can hurt it, then every time you don't play you stuff at full tilt it could blow. yeah pretty much. so theoretically every time you lower the volume, your stuff will blow. it wont happen. only reason things blow when being under powered is because stupid people crank settings up and cause the amp to distort cause they think it should be louder.
deathcards Posted May 24, 2012 Report Posted May 24, 2012 yea it is crap i use to think so but then my sub should have blown years ago so no it doesn't ruin the sub i had about the same thing to two subs about 200 each stupid screws were junk that i used though box was junk also stripped a screw hole out and broke two and i was wondering why it wouldn't seal lol skar sk2500.1 0 gauge power and ground kunukonceptz alpine HUvxi65 components on BA gt-275new build log -> http://www.stevemeadedesigns.com/board/topic/150642-project-d-kon-deathcards-build-log/#entry2148821 2 x-15 sundowns singer alt, odyssey bat, and maxwell ultra caps

ZachG Posted May 24, 2012 Author Report Posted May 24, 2012 Oh ok, was just wondering cause I got a 250watt amp now wired up, & I got a 1500rms amp waiting to be put in after I run my 0 guage but won't have time for a week or so. 1998 Pontiac grand prix gtp supercharged2 12" Obsidain Audio V.1 on a 2011 zx1500.1 at 2 ohms. 20ft of Knuconceptz CCA 0 Guage. 2nd Battery is a Shurken BT-120.
