Low watts to high watt sub?

[aek 10+ year member]

Currently I have 2 10" Rockford Fosgate Punch Stage 1 (150 watts rms) and I am using an ancient Jensen 100 watt x 2 amp (40 watts rms per channel). So far I havent cranked it up much, but if I do, do I risk hurting the subwoofer or the amp, possibly both?

Thanks

Well, not really with that little power. Even at full clipping we are only talking about 80w to each sub, which is less than half their power handling. Though, clipping the amp isn't a good thing no matter which way you slice it. Just set your gain and bass boost correctly and your set (for now). However, I would seriously look into getting a new amp.

not really....all ur doing is underpowering ur subs by far

I have a Profile AP1200 comming tuesday, but this amp I have right now will have to do I suppose //content.invisioncic.com/y282845/emoticons/furious.gif.fc81ca146dbff91fede3ed290dbc4f4c.gif

you wont hurt the sub with that lilbit of wattage. but it if you turn the gain up too high to where you hear it start cliping turn it down, why? cus lets say that amps puts out 25volts at 4ohms "most likely more" that's 156.25watts!sounds like alot for that amp right! its at clipping which its a combination of a sine wave and a dc current. the DC current will over heat your sub and kill your voice coil.

so watch out for the clipping part.

And that's assuming the amp can even actually do 40w per channel. It's likely overrated.

l0l... an underated 40 watt amp... hehe

it would not be sound its an AC signal with a flat top of DC Current. usualy kills ether the mosfets in the amp or the voice coil in the sub.

Clipping in and of itself does not kill subs. Cheap amps? Possibly. But not subs.

And yes, a clipped signal is still "sound" (alternating current going to the coil will still cause the sub to oscillate at the frequency of the signal)......not even sure what you meant by that //content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif

if you have a sub that can take the current from a clipped signal "off course you re not going to kill it, but you could damage the amp.

if its a weak sub like the RF P1 series im sure a low frequency clipped signal will do some damage to the sub, or the amp.maybe not but why risk it?.

i could make noise with a 9V battery and a speaker. but in reality its not a sine wave which its what i refer to as sound. a clipped sine wave carries DC voltage in which again is noise. not sound like in music "sine waves" ,its more like a square wave which again is not sound, but again it makes sounds.

if you feel confotable pasing clipped signals trugh your speakers by all means do it.

but dont missinform people in to thinking that its ok and it wont damage any thing because its dependent of many factors and there is no asurance that it wont damage the speakers or that it will. so with that said,

watch your gaing and if you hear clipping turn it down some.

They both seem to know their shit, but they just have different opinions on the current topic, which is just fine. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

PowerNaudio, you preach like your a smart guy but sometimes you are down right foolish.

OK!. and how did you determined that?

I'm not trying to preach, I'm not trying to sound smart, I'm just trying to help!, which is what this form is all about.

ill stick with the facts, do a quick search on googles on clipping and youll find all sort of info on it. the more you educate your self the more you know, the smarter you sound and become.

later.
