eclipse 34230

My nephew has an eclipse 34230 amp- he just bought a Diamond Audio D315D4.2 15 that we need to get wired up...the sub is 4ohm dvc and rated for 500w rms 1000w max. As far as I know the amp is 2 channel non bridgeable, Ive read that this amp is 4 ohm and 8 ohm stable, and that its a dual mono...
