Lpine Type-X 5.25 component speakers- Crossover problem
You can use any providing you can determine the max voltage in the device and the polarity.
If the capacitor in the unit has a wire out of each end and both ends have indents then it's a non-polar type.
Speaker capacitors for tweeters tend to be around 2uf.
The Voltage of the capacitor should be bigger than any voltage in the device.

Amp Was Extremely Hot and I Have Now Lost All Sound
Where was the smell coming from? The amp or the sub?
Do you have an ohmmeter to check to see if the sub's voice coils are still intact? Can you try driving the subs with another source to verify they are ok? We need to eliminate the variables here.
If the subs are okay then it's obvious that the problem is in the amp. I'm not sure if there are any protection devices internal to the amp, but I am sure if you remove the cover from the amp and if it was amp that was producing the burnt smell, you'll have no trouble visually identifying where the problem is in the amp. Most likely you'll find a part that is discolored or black & burned.
Usually a smell like this from a solid state device indicates a component has been overheated and if run long enough in this condition will fail.

Arcam Alpha 7 amp. Internal 240v 25A fuse blows
Fuses blow like this due to an overload. The cause being a semi-conductor such as an IC or transistor acting like it was a piece of wire. The most common cause is a shorted output transistor(s) in the main amp. But the power supply can't be ruled out. If you have an ohmmeter then a shorted device will be easy to spot. As it will be just like you have touched the probes together when a part (even in circuit) is tested.
