Testing Amp Wattage?
|
Bronze Member Username: Koondawg06Post Number: 35 Registered: Sep-06 | Is there any way to test how many watts my amplifier is putting to my subwoofers? My amplifier is bigger than my subs so I'm afraid to blindly turn the level and bass too high and blow my brand new subs, however I want to maximize what my subs can handle. If there are any devices or suggestions I'd appreciate to hear from you. Thanks!  |

If your subs are say 500rms each and your amp is 1,500rms, they will be fine. When you crank the tunes mega loud your amp will try to push more power than it can causing distortion which is how you blow subs really fast. Overpower them a tad is usualy trivial, I am giving my subs 2,000 more rms then is reccomened and they are fine, just don't drive around with the voulume at 3/4 full. |

With these tools, you can power the amp without fluctuation in input or output, and read the output voltage and current on the scope. |
