I have a transistor amp rated at 200 watts RMS into 8 ohms. What would the output be for 14 ohms or how to calculate it ?

Roughly, half, though not exactly. Here's a formula...



1. Ohm's Law deals with the relationship between voltage and current in an ideal conductor. This relationship states that:

The potential difference (voltage) across an ideal conductor is proportional to the current through it.

The constant of proportionality is called the "resistance", R.

Ohm's Law is given by:

V = I R

where V is the potential difference between two points which include a resistance R. I is the current flowing through the resistance.
 
How are you getting 14 ohms?

16 ohms (much more common) will give you 100 watts. You won't notice a volume difference all things being equal.
