[QUOTE="maylar, post: 8160058, member: 541144"] [quote name='calebkhill']So a single vice coil bridged across any amp will still be "bridged at 4ohms" How does bridging work with dvc, the load changes right? Run both ++ and both -- to amp terminals, your gonna have 2ohm on each channel right? [USER=541144]@maylar[/USER]; If you can, explain this whole thing for us....[COLOR="Silver"] [SIZE=1]---------- Post added at 06:22 AM ---------- Previous post was at 06:21 AM ----------[/SIZE] [/COLOR]How do you keep a dvc bridged at 4 ohms fur 2 and 4 channel amps?[/QUOTE] A sub's impedance is independant from whatever it's hooked up to. A SVC 4 ohm sub is 4 ohms, bridged or not. A DVC 4 ohm wired in parallel is 2 ohms, bridged or not. So, this statement is only true [B]if[/B] the SVC is 4 ohms: An amp that can handle 2 ohms per channel will handle 4 ohms bridged. Bridging adds the 2 channels together, doubling the voltage across the load. But the amp has a limit to the current it can output safely, so to not exceed the max current we need to increase the load impedance by a factor of 2. Twice the voltage and twice the impedance is the same current. I suppose it would be accurate to say that with a 4 ohm bridged load each channel of the amp sees 2 ohms, but IMO that's just making the matter complicated. [/QUOTE]
