Don't feel like getting into details, but will there be a change in DB, or power levels if running your subs at 2ohms, instead at 4ohms.

Basically I had 2 options, and went with the 4ohm load.

 

Your amp will put out a lot more power at 2 ohm than it will at 4 ohm.

The idea is to match the speakers with the amp. Mono block amps are usually stable @ 2, sometimes @ 1 ohm. Check specs.

Before i bought subs, I already had 2 stereo amps, but they are only stable when bridged @ 4 ohm. So i bought 2 subs, dvc 2 ohm, so they matched the amps i already have.
Now that i want more power, but already have new subs, i need 2 amps that will run @ 1 or 4 ohm, or 1 amp that will run @ 2 ohm.

 

Basically my amp will run at 4,000w Max, or 2,000w RMS, bridged at 4ohms.
Manual said I can do a bridge, at 2ohms per channel (2 channel amp).
Subs are a 4ohm duel voice coil.

I just went with the single bridge at 4ohms, and wired the subs (as 12volt.com) recomended. (series/parallel) = 4 ohm load.
