TheNewbie Posted December 2, 2011 Report Share Posted December 2, 2011 Q: is it okay to underpower a subwoofer? For example. A 2000w sub, with a 1000w amp. Thanks for any input. I keep hearing mixed information. Quote Check out my build log: http://www.stevemead...60#entry1958353 Different folks have different strokes.

CHEVY4X4BLAZER Posted December 2, 2011 Report Share Posted December 2, 2011 As long as the power is clean. You should be okay. Just understand that the sub will not perform to its potential on half rms Quote Link to comment Share on other sites More sharing options...
Winn Posted December 2, 2011 Report Share Posted December 2, 2011 (edited) Dont clip it you will be fine... Dont try to push it to its limits cause you will probably clip it Clipping is when your amplifier trys to produce more than its suppose to causing the volts to drop and amps to rise... Which will heat the amp and maybe blow..... Also it starts sending DC voltage instead of AC voltage when clipping Edited December 2, 2011 by Winn Quote You know how you avoid that? Man the fuck up and bang her best friend sister mom cousin worst enemy and never look back. JUST SAY ANTI-AUDIOPIPE Link to comment Share on other sites More sharing options...
TheNewbie Posted December 2, 2011 Author Report Share Posted December 2, 2011 Right, thanks guys. Just to clarify if I have an amp that will cleanly push 1000w, it wouldn't do harm to the subwoofer to push 200w out of that amp to the sub. Correct?

kam311 Posted December 2, 2011 Report Share Posted December 2, 2011 Not at all! What do you think happens when you turn the volume down on your head unit? The reason the "underpowering a sub blows it" myth exists is because when underpowering a sub a lot of people crank the gain all the way up or way past where it should be because they think their sub can handle moar powa!!!! But as we all know the gain knob isn't the volume knob. Set the gains right and there is no problem Quote so far...

I was guilty of that ^ haha not setting the gains correctly. Gotta get me a DD-1 here veryyyy soon. So people put the gain up alot more, so they can get more bass at a lower volume, but being that the gain is cranked most likely more than 3/4ths it causes clipping at a lower volume correct?

TheNewbie Posted December 2, 2011 Author Report Share Posted December 2, 2011 Saw this on the forums Clipping A signal that results from an amplifier that is either overloaded or underpowered relative to the signal Amplitude it being asked to generate. This confuses me a little, disregaurd the message i posted above as it will mostly be repeated just going to try to sum it up, so basicly if the amp gain is set to low it can cause clipping as well if it's to high. It has to be juuuust right. If that's correct then i also have another question. Sorry for the 20 question game, was just really curious on this subject, trying to read up on it so there isn't to many thanks Quote Check out my build log: http://www.stevemead...60#entry1958353 Different folks have different strokes.

P-rez Posted December 2, 2011 Report Share Posted December 2, 2011 Just don't try to push it to get it loud with 1k cuz u will clipp the Shit out of it Quote Its All Good!!! Build on hold... Link to comment Share on other sites More sharing options...
TeamHT Posted December 2, 2011 Report Share Posted December 2, 2011 The amp is underpowered, not the sub. You misread what was posted. It takes power to make power, and if you expect an amplifier to make 4,000 watts without sufficient power, it will try to anyways resulting in clipped signals.
