rockford sub and amp question

Ok so it will be safe for the sub to be underpowered a bit?

Underpowering can lead to clipping which is not good for the Amp or the Sub in the long run. That amp is a good selection due to it being Class D and will run cooler and more efficiently than your standard Class A/B amp. Considering the amp is 500w RMS @ 2ohms, you want to provide it with a 2ohm load to take full advantage of it's power output. I would use a 4ohm DVC sub(P3D4-12) and wire it for 2 ohms(unless you have purchased the sub already). Another way to maximize bass output is "corning loading". Placing the sub as far back in the Hatch area and in the corner will provide more output at a given frequency depending on the resonant freq of the sub/enclosure and vehicle acoustics. All in all, 500w RMS is plenty in a 370z.

Not exactly true, but in a roundabout way........ Underpowering will never harm your speaker. The harm comes when people increase the amplifier gains to get louder, and put the amp into clipping. When gains are set properly, clipping is not an issue, and any amplifier will suffice.

^This. I forgot what exactly they both said, and they said this exactly.

And most people set the gain way too high because it sounds louder.


RF sets the gain where it should be.
