[QUOTE="squeak9798, post: 788141, member: 555320"] Just some technicalities that may sound stupid, but really change the whole meaning....... The amp doesn't have an impedance (for our purposes). There is no 2ohm amp. Using that term is really just, well, wrong. The amp is [B]stable to[/B] a 2ohm load per channel. It's the speakers (or subs) that determine what impedance the amplifier is actually driving. And an amp that is [I]stable into[/I] a 2ohm load per channel is only only [I]stable into[/I] a 4ohm load bridged (think of it as each channel essentially "seeing" half the load when bridged, so a 4ohm load on a bridged amp makes each channel "see" a 2ohm load). Anything lower than those impedances (2ohm per channel, or 4ohm bridged) and you risk damaging the amp. So, bridging an amp that is stable down to 2ohm per channel doesn't automatically make it 4ohms. But an amp that is only stable to 2ohm per channel will only be stable into a 4ohm load bridged. You can wire a 2ohm load to the amplifier bridged......but you run a very high risk of damaging the amp, and hence it is not recommended [IMG]//content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif[/IMG] Can't hear subbass in stereo, which is why mono amps work and why many people get away with only have a single sub. Essentially the same thing. And it would be 250w x 2 @ [B]2[/B]ohm Yes, that is correct. But no, the subs aren't really "changing" impedances. The only subs that can be wired into different impedances are dual voice coil or quad coil subs. With dual voice coils, you can wire the coils in series or in parallel to arrive at different impedances. This can only be done with speakers that have more than one voice coil. So, they aren't really "changing", it just gives you more wiring options for flexibility (opens up your amplifier options by being able to wire the sub(s) to different impedances) [/QUOTE]
