Guest Posted March 28, 2009 Report Share Posted March 28, 2009 Since my old amp doesnt have a subsonic filter, im resorting to using a small capacitor in-line with the + wire going to the sub. i used the calc on the12volt.com and it said i need a 1000ufd cap to have a 40hz cutoff at a 6db slope with a 4ohm speaker. my question is, will this capacitor work? http://www.radioshack.com/product/index.js...oductId=2103627 Quote Link to comment Share on other sites More sharing options...
Stephen Posted March 28, 2009 Report Share Posted March 28, 2009 6db slope? Quote you can cook bacon shirtless if you're not a pussy...lol not hatin, but am i wrong here it looks as if the amp is not grounded its hooked directly to the battery. it that the way it should be.

Guest Posted March 28, 2009 Report Share Posted March 28, 2009 does you amp put out more than 50 volts? no, im running it bridged, since it a 4 channel, at 30v. i was thinking about that voltage rating but its for DC, so i dont know what it would be for AC Quote Link to comment Share on other sites More sharing options...

It's sub bass...it's a pretty damn easy signal, you could carry it over a coat hanger.
