i was watching tuner transformation and i saw that they used knocept Audio.

Has anybody used Knocept Audio?

the stupid thing was the Knocept installers used a 700w class D amp on 3 1000w rms subs. Thats only 233w each !

That's not messed up...

The RMS rating on any subwoofer is an upper limit.

In other words, "if you feed any more power than ____ into this subwoofer, you risk thermal damage".

Less power is always healthier... less current flowing through a voice coil = less heat = longetivity, reliability. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

How much power you need is a different story...

...and that's completely dependent on your enclosure, and how much efficiency you've dialed into that enclosure design.

Remember, Hoffman's Iron Law states the following three items are mutually exclusive in a subwoofer/enclosure alignment:

1) small enclosure size

2) low frequency extension

3) high efficiency

So, if you've designed an enclosure to extend as low as possible in the smallest box possible... you've thrown efficiency out the window.... and hell, you might need more than the RMS rating of the sub to reach maximum excursion with that sub.

But on the other hand, if you build the enclosure larger, you can increase both low frequency extension, and efficiency.

For a great many years, I had some JL 10W6's in a 4.5 cu.ft. enclosure, tuned to 32hz... running off a 400w Alpine amp. Each 10W6 was rated at 300w, and JL is notorious about conservatively rating their subs (almost to the degree of lying). That works out to 133 watts per sub... and I was pushing the subs to max excursion, max output - by design. Rear window could turn to jello... and this being a SQ alignment! //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

Efficiency is in your hands!

Now... would I trust the guys at WCC to design an enclosure that was efficient, built to properly mate those subs to the power they were feeding them?

....fortunately, they seem to outsource most of the audio designs on that show. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

I hope so, because I seen mad mike did a setup running bazooka amps and tubes and he claimed a whopping 6000w of "bragging" power. I almost choked up my chocolate milk when I heard that one.

tuner transformation!!!!!

they don't know what the h*** they are talking about. I amazed by all the car shows on TV these days, most are ricey and garbabe like Pimp my ride.

Overhauling with Chip Foose, now thats a example of somone who knows what the h*** he is talking about although they don't seem to do much audio.
