I'm looking to get a new amplifier to replace the one I currently I have, but I don't know much about the all the different ratings. I've read that too much/too little wattage can damage the amplifier or speakers.
My speakers have a rating of 100 (no units) and 8ohm
My current amplifier is 100 watts. It has a number of screws for attaching speakers but I believe the pair of speakers is connected to the common and 4ohm screws. (it also has ground, and 70V and 8/16ohm connections IIRC) It was professionally set up around 14 years ago, so I don't remember to much about it.
I want to replace this with a stereo amplifier. What would be an acceptable wattage/ohm/voltage to replace the old one?
EDIT: Ok, I found the booklet for the amplifier and it appears that for the terminal connections being used the speaker line is 4 watts unbalanced
EDIT: Further reading reveals the amplifier is a Bogen CT100C and the speakers are (2) Paso C324THP sound columns
Depends what kind of music you listen to. For example, classical music has up to 60dB peaks. 60dB = 64 times the power required. So if your listening level averages to 1W, you need ~70W/channel amplifier to avoid clipping.
If your amplifier clips repeatedly it can damage your speakers, as the voltage surge does not allow the voice coils to cool properly.
