Is a 3 cube box too big for an sa12

Unless the subwoofer is perfecly engineered to have no mechanical noise/distortion up to Xmech, you'll be able to hear it easily.(unless you crank it up as fast as you can...)

You won't break the triple joint unless the joint was sub-par or you saw that it didn't get louder or excursion stayed the same and still continued to turn it up more.

But how would you exactly figure out how much power you can put to the woofer?

If you push any sub too far eventually something will fail. I agree with you that the sub will probably tell you before that happens as long as you are diligent and attentive enough. But there is no guarantee that will happen and if it doesn't give you warning it will be re-cone time. It's up to the user to decide just how much risk they are willing to take in the pursuit of more performance.

As far as how much power the sub can take, it's rated at 600 watts. I know a lot of folks use a lot bigger amps than that, but I also suspect people are not putting nearly as much power to their subs as they think they are due to things like impedance rise and power factor. The best thing to do would probably be to call Sundown and see what they recommend. If the user then chooses to exceed what Sundown recommends and they break their sub the onus is on them.

How do you set up the amp that it puts out 600W at all frequencies with the subwoofer connected? (unless you wil play all the freqencies from 20-60Hz and measure power at every frequency.)

Well amps are constant voltage devices, so they wouldn't put out 600W at all frequencies. They are going to put out the most power where impedance is the lowest, which with ported boxes, is going to be at the tuning frequency. The best way to do it would be with something like an AMM-1 then you could adjust your gain so that you got 600 watts at the tuning frequency, with your HU set just below clipping, with a 0 db signal (or whatever you wanted to use), etc.

Sounds like youre trying to save money on your enclosure.

Why not just reinforce the hell out of the box from the inside resulting in less box volume?

filling up the box will screw up the tuning of the box since the port will still be the same

what they recommend is already on the manual.. dont waste your time calling them.. for warranty reasons they wont tell you that 1500 watts on a oversize enclouser is fine.. you can ask any sub manufacturer and they will all tell you rated rms nothing more

This was not my experience the last time I called them. I asked reasonable questions and got reasonable answers, not just CYA warranty speak.

If Sundown does tell them that 600 watts is it due to warranty concerns, they are no worse off. They still have to decide for themselves how far they want to push things.

i don't understand the big boner people get from overpowering subs? can you honestly hear a difference? i prefer to follow instructions and not constantly be smelling and looking at the sub and worrying about that shit so i can just focus on enjoying the music. but hey thats just me

given that this guy asked this simple question i wouldn't recommend throwing more power to any sub. 1k in a recommended spec box okay.. throwing 3x its rated power in a large enclouser is just asking for trouble. you hear about people throwing 10% maybe 20% over the rated power but this guy is trying to run 342% over its rated power
