Ohms question
If I have a amp that is 2 ohm stable and have no plans on bridging my speakers, and the speakers I am interested in are available in both 2 and 4 ohm is there any reason to not go with the 2 ohm version and get the extra power ? Sorry if this is a basic or common question.

Every motorcycle amp Ive seen that is a 4 ohm amp is also 2 ohm stable. Just because its 2 ohm stable doesnt mean it should run 2 ohm speakers.

Modern solid state amps are more forgiving of speaker load and will usually quote power at different ohms (example). However, if the manufacturer doesn't quote different ohms power specs there may be a reason. The only thing I'd advise against is mixing speaker ohms - that's a sad story due to sub optimal sound. So I'd stay to within manufacturer specs and also not mix speakers say front to back or whatever.
Most of these are class d and the clean power quotes are often outrageous exaggerations.

My amp is a DS18 Ion1600.4, for speakers i am looking at the Diamond MP65 either 2 or 4 ohm. These will be going in the fairing.

I'm running a cicada 1400 amp and I have 4 ohm Arc coaxial speakers in the fairing and 2 ohm Cicada CXX69 speakers in the bags. It's a perfect balance as I don't need more power in the fairing as about 175 watts up front works with 4ohm but I run about 250+ to the rears with 2ohm and I the7 are loud at 80+ miles an hour. I had 4 ohms in the bags but I would lose them at speed. Crossovers are set at 110hz front and 130hz bags. The fade feature does come in handy to have times.
