Could be a blown fuse or your ground got disconnected. Check all your connections and make sure everything is tight

Why is my Jensen SPX-17 home entertainment subwoofer only putting out about 10% functioning base power volume level and loudness?


Gary, If you have the subwoofer open, what did you keep from measuring the voltage of both power supplies? And while measuring, why not put a load on both, and see what current they can handle?
When the error moves with one component (power supply) the error must be there. Without a multimeter, (I have several, but I'm not close to the power supplies) you can't tell if the power supply is working to full performance. So start there.
Just try to find out, if a part of the rectifier is defect (one diode) It won't be possible to point out what is wrong, if you can't measure on the device yourself.
Sorry.

Whats rms on legacy la1490


http://en.wikipedia.org/wiki/Root_mean_square
In mathematics, the root mean square (abbreviated RMS or rms), also known as the quadratic mean, is a statistical measure of the magnitude of a varying quantity. It is especially useful when variates are positive and negative, e.g., sinusoids.
However, the term "RMS power" is sometimes used in the audio industry as a synonym for "mean power" or "average power". For a discussion of audio power measurements and their shortcomings, see Audio power.

How many watts is it


http://www.kenwoodusa.com/UserFiles/File/Global/Consumer/Manuals/kac528.pdf

Page 7 of the manual gives you all the different configurations of this amp, and it's MAX power. FYI; Kenwood rates their amps at MAX power, not clean. Hope this helps.

V12 MRV-1507 or Xplod? Amplifier - XM-ZR1252 good quality sound


Alpine is just a better brand in general. I have the older MRV-1507, sounds GREAT, i have had friends who has had the Explode line, but it was always a temporary system until they got something better, like the alpine or kenwood.
