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!  |

How much more rms is your amp than your subs?
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. |

well my subs are 400 rms a piece,.. my amplifier has 1920 watts written on it but I'm not sure if that's rms or not.. here's the links to what I've got.

440 Watts x 2 @ 2 ohms
Just wire each sub to its own channel and your good. |

to truly see the output of an amp, you need a non reactive dummy load, a regulated power supply for the amp, and an oscilloscope with non-inductibve leads.
With these tools, you can power the amp without fluctuation in input or output, and read the output voltage and current on the scope. |

just set your gain using a DMM and 0dB test tones.
It's a pretty simple process - a lot of forums have sticky's on the topic.
Check the amp sectio at caraudio.com |
