TheBussman1647545507 Posted December 9, 2005 Report Share Posted December 9, 2005 i need an amp that will push 2 10inch subs effecivly, thinking around 500W?? i might be able to get some numbers for you soon. Link to comment Share on other sites More sharing options...
armin922 Posted December 10, 2005 Report Share Posted December 10, 2005 look at the specs at the sub. It should say like 4ohm ______RMS. Then look at the amp. Look for the part that says 4ohm and see the RMS for that. Make sure your amp has enough RMS to power those amps. Underpowering an amp isnt a good thing and so is overpowering. So look for an amp that will be fine for the speakers. If u dont know what RMS means heres the breakdown......... Defining RMS and Peak power handling: RMS (more accurately called continuous power handling) is the measure of how much power the speaker can enfure for extended, continuous periods of use. This is an average rating since music, and thus the power required to produce it, is dynamic in nature and varies greatly from moment to moment depending on the frequency being produced and mechanical characteristics of the amplifier and speaker. When pairing an amplifier and speaker or speakers, you should try to match the amplifier's power output to about 80% of the RMS rating of the speakers, at the load they'll present to the amplifier. This is a good, safe region to aim for if you're unsure of how much power the speakers actually need, and is a very generalized rule of thumb. Note that RMS ratings for speakers apply to a clean, AC voltage being applied to the speaker. If the signal is clipped in any way, the resulting DC voltage will cause the coils to heat more quickly and to greater temperatures, causing damage at what may be an amount of power well below that of the RMS rating. Peak ratings are strictly meant to tell you how much heat the voice coils of the speaker can take for a brief, momentary burst of power without essentialy blowing apart the speaker or melting the coils on the spot. This measurement isn't very useful in real world application so it's best left ignored for the most part. In conclusion, please keep in mind that just because a speaker may say it's rated for 2000 watts RMS, that by no means implies that you actually need that much power to get full output from the speaker. In fact you may need as little as 300 watts RMS to achieve peak excursion in teh right enclosure. This is a common misunderstanding by a large contingent of the car audio world, and one well worth addressing. This is why many people will tell you that you don't always need thousands of watts of power to have a loud system. Link to comment Share on other sites More sharing options...
cinergi Posted December 10, 2005 Report Share Posted December 10, 2005 If you can get me the model number and ohm rating I can get you an amp... This soundstream I have would probably work well.... Link to comment Share on other sites More sharing options...
TheBussman1647545507 Posted December 19, 2005 Author Report Share Posted December 19, 2005 can't find a model number, i guessing the cheaper end, all i can fin on the back is: 4 ohm 550 590 Link to comment Share on other sites More sharing options...
