How to wire D4 sub to 2 channel amp for most power?

[PuZo 10+ year member]

I am selling a leftover sub and amp to someone, and I want to know, since the sub is going to be underpowered either way, what is the best way to wire it? Its a 2 channel amp. This is the info I have about the amp

CEA 2006 Compliant Amplifier Ratings

12.6 Volt Power Output Specifications

50 WRMS per Channel @ 4 Ohms and 1% THD+N

96 WRMS per Channel @ 2 Ohms and 1% THD+N

160 WRMS Bridged Channels @ 4 Ohms and 1% THD+N

14.4 Volt Power Output Specifications

65 WRMS per Channel @ 4 Ohms and 1% THD+N

100 WRMS per Channel @ 2 Ohms and 1% THD+N

200 WRMS Bridged Channels @ 4 Ohms and 1% THD+N

The sub is 450 RMS, probably overrated, so can I only wire it at 4 ohms? Thanks

some 2channel amps can handle 2ohm mono, but most can't so wire up to 8ohms

Wont that reduce the power even more? Would it best best to leave it at 4 ohms?

if its a d4 you only options are 8 or 2

It 2 ohm stable, but on the specs it doesn't mention 2 ohm being bridged, would that still work?

you may have less power at 8ohm, but way better thd so it'll probably be plenty loud. I've run man subs at 8ohm and they don't lose much output

it won't work for long. what brand is it? if its not RF, PG or something like that don't try 2ohm bridged

The amp is Fusion fe-402 and the sub is some custom built one, dont have any specs on it

if I were u, I'd just run it at 8 ohm until you can get another 2ohm stable amp
