Do I need thicker wires?

I recently upgraded my rear and side surround speakers to 4 ohm Polk LSiFX. I have a dedicated high current NAD amplifier for these speakers.
Because these are 4 ohm speakers with a high current amp, do I need to upgrade my speaker wire from 14 gauge to a thicker gauge ? The total run is about 45 feet.

    Always, as heavy as you can be and also practical is good. If you have Dolby Digital for your movies, then your back speakers should be set at large because the complete frequency range is delivered to them when called for. If your back speakers are not full range (satellites) then they will not be getting the lower frequencies if you set up your amp right. The wiring should be sufficient with 14G either way. Surround speakers should be fine at 14G.
