I will be using four Phoenix Gold ZPA amplifiers in my next build. Two of the ZPA 0.5 will be used to power my subwoofers. I am considering two ICON 15".

All four of my ZPA have v2 mods as well as cap replacement and the two 0.5 wil have upgraded power supply components. At a 4 ohm mono load the 0.5's output is around 1200w, at 2 ohm mono output is around 1600w. Since these are class a/b amplifiers current draw increases fairly significantly at 2 ohms mono.

Do you think I should use these amps at 4 or 2 ohm mono load? I would think that the damping factor would also be lower at 2 ohm mono. This is a daily install and the design goal is more SQ orientated than SPL.

BTW I can uograde to a 390a alternator if needed. Vehicle is a 2013 Chevy Traverse.

You won't hear a difference

I didnt think so.

Thanks for the reply.
