mosfet bridgealbe means i can brige the amp rite???? (lol) when i go to bridge my 3 12"s, no power goes to the subs...wtf is wrong???? (im taking all the positives and putting them on positive on one channel and all the negatives and putting them on the negative on the other channel) (2ch amp 2000watts 2ohms) n e one know whats wrong???

mosfet -- type of transistor. usually a buzz word meaning nothing in car audio.

As thch rightly said...MOSFET is a type of transistor and not really relevant at all to your question. Companies unfortunately like to throw it around as a marketing buzzword.

As to your question....what is the resulting impedance from having all of those subwoofers in parallel? And what amplifier are you using?

Chances are good that the resulting impedance is below the stability of that amplifier bridged, which is causing you some problems.

Also, do you know for sure that the amplifier even works? Stupid question, but you never know. You could grab a DMM and a test tone, and measure the voltage output of the amplifier to be sure it's even putting out power.

its a 2000watt volfenhag, 2ohm stable..2 channel

2ohm stability likely refers to per channel, not bridged.

That amplifier is probably not stable below 4ohms bridged.
