Question about Sub/Amp setup

If the amp is 300w RMS @ 4 ohms and 14.4 volts, yes, it will.

Assuming a near-perfect enclosure, meaning airspace is correct, and the enclosure doesn't leak, you'll have some nice bass out there.

I have 300W RMS going into a single JLAudio 12W3; the enclosure is perfect ( I built it, and I've been doing it a long time) and it thumps, big time. The fact my signal is EQ'd helps too. 😉

That is incorrect. CLIPPING, aka "Distortion" is not good for any speaker. "Underpowering" is a subjective assessment. The woofer in question is rated at 500 watts, RMS. That means it can reliably handle 500 watts of power, consistently, w/o damage.

300 watts is plenty to get that sub moving. Now, if it was 50 watts, that would be different. That would be grossly "underpowered" and there would be a lot of clipping/distortion.

How do you clip with 50W?

Exactly. That should give you some pretty good bass. If the sub is dual voice coil, you could run it at 2ohms and get a little more power out of the amp.

How do you clip with 50W?

You can clip with 50 or 5,000 watts. 🙂 Clipping happens when you overdrive an amplifer's output ciruits. The waveform changes from a sine wave (think nice rounded ups and downs) to a square wave (think "squared off" ups and downs). That is what damages speakers. TRUE, you can burn out a voice coil with too much power...but if it's CLEAN power, you REALLY have to be over doing it.

Overpowering a woofer usually results in a torn surround as woofer cones move a lot, as the voicecoil moves a lot up and down in the gap.

Overpowering a mid or tweet usually results in a burned voicecoil, as the cone doestn' move all that much.
