Guest Posted March 24, 2013 Report Share Posted March 24, 2013 Just got a new SA-12 2ohm DVC and threw it in a ported box w/ 1.75cft wired @ 4ohms only feeding it 300w and it's clipping, could it be the temporary enclosure it's in, or it being under powered, any other ideas?

Wicks Posted March 24, 2013 Report Share Posted March 24, 2013 How do you know it's clipping? More detail on your complaint of "clipping"? Enclosures can't cause clipping. You can't harmfully underpower a speaker either.

Kranny Posted March 24, 2013 Report Share Posted March 24, 2013 boxes dont make woofers clip. the user does. underpowering doesn't cause clipping unless the user overdrives the amp. Quote Link to comment Share on other sites More sharing options...
Guest Posted March 24, 2013 Report Share Posted March 24, 2013 (edited) The amp puts out 300w @ 4 ohms RMS, I've got the gain at 1.0v & there is no bass boost set on the amp/HU and it's clipping with the volume on my HU at 10 out of 40 (HU clips signal at 36) I'm saying it's clipping because the sub is like, vibrating/distorting, you can hear it outside of the car w/ the trunk closed Edited March 24, 2013 by Guest Quote Link to comment Share on other sites More sharing options...
Kranny Posted March 24, 2013 Report Share Posted March 24, 2013 how in the world can you tell its clipping without testing equipment? Quote Link to comment Share on other sites More sharing options...
Raptorman Posted March 24, 2013 Report Share Posted March 24, 2013 How do you know you are clipping? Bass knob?

TheBetterMethod Posted March 24, 2013 Report Share Posted March 24, 2013 If you have the gain set at 1 volt, that's probably the opposite of what you want. Your gain says something like .5-5.0 volts right? Your head unit puts out 2-5 volts most likely. So your amp needs to be set the same, not at the lower voltage. If your head unit puts out 4 volts your amp needs to be set to 4 volts. Otherwise you'll clip.

Guest Posted March 24, 2013 Report Share Posted March 24, 2013 (edited) Yes, I know subs are supposed to move. I don't have any equipment to test it with..but you don't always need equipment to tell that a signal is clipped...lol.. HU's preamp voltage is 4 volts, I never knew that TheBetterMethod.
