[QUOTE="LaidD3athl0rd, post: 8439849, member: 650415"] I have already tested for all of these possibilities, the woofers have a combined resistance of 1.6 which is aimed at 1.3 ohm load but you'll always get a bit of play over the space of wiring 3 woofers. i have made a test bench up using completely new wiring, a new head unit and new speakers. I think its quite clear its something to do with the speaker terminals. Because when i measure the terminals i receive nothing, the resistance also stays the same which should vary with the music and power output. Also i cant even purposely get it to go into protect mode, i tried purposely shorting the speaker terminals by connecting a wiring from one to the other and even then the protect light wouldn't come on. It must be something with the speaker terminal electronics, its as if they are not connected to the rest of the circuit. The protect light should come on under thermal, short and voltage issues. its not getting hot so it cant be thermal, the voltage on the test bench is a consistent supply from a charger at 13.8v, and like i said i purposely cant even get the protect light to come on under shorting the speaker terminals. very odd.
