Id like to use a marine radio/cd player to power my 4 outside rock speakers. They are 8ohms but the marine stereo (waterproof) puts out 4ohms. Will this work and if not, how can I incr from 4 to 8ohms easily ?
No problem. 4 ohms actually is more stressful to an amplifier as it requires twice the current of 8 ohms. Also, 4 8 ohm stereo speakers is a 4 ohm load, as ohms are usually measured in per two speakers. Ohms are not like voltage, higher is actually LESS resistance.A 4 ohm amp can drive anythingg 4 ohms or higher.Craig http://hometheaterinsider.net
