Brand new sub smells like electrical fire?

[QUOTE="audiobaun, post: 8855093, member: 634282"] Well, to start with #1- That amplifier is only 4ohm stable bridged so you cannot go below that ohm value Bridged mono. #2- The sub is DVC4 ohm and can be wired with both coils at a final Ohm load of either 2 ohm(of which that amp is not capable of handling) or 8 ohm which it can be wired to to work fine. [URL unfurl="true"]https://www.the12volt.com/caraudio/subwoofer-wiring-diagrams.asp?Q=1&I=42[/URL] Its not a great combination. If you have wired @ a 2 ohm load, you will end up frying the sub and frying the amplifier at some point. To use that amp..
