How many watts does it take where it gets tot he point where you here rattling rather than bass? This is without dynomat.

 

No such thing as too much power. Kind of like haveing too much money or too much fun.

 

Watts aren't really the issue with speaker performance and/or rattling. There are lots of variables. Box type (sealed, ported, vented), quality of components and also what direction you are firing your subs.

Rattles can be caused by a number of things: loose tail lights, loose license plate frame, loose plastic in a variety of places. Start tightening things up and maybe using matting and/or tape to keep things from hitting each other. I used to use thick one-sided foam tape to keep my licence plate from rattling on the back of the car. Sometimes, a box isn't made well and it will rattle, too.

Just spend some time listening to where the rattles are coming from and tightening things.

 

 

SO If I put 1000 watts into to elemental k's I can get rid of any rattlying if there is any?

 

it's not about ratling or the size of your sub...it's about the quality of the car and the resonance frequency in the metel....5 watts at a given frequency could make it rattle just the same as 5000000 watts.

i have 2-12" kickers with a 600watt amp and i am satisfied.. if i had money, i would get a 1200watt setup with new headunit, speakers, tweeters, amps for the speakers...
but with stock speakers and head unit, i think 1000's too much bass.... imo

 

This might not be what you are asking, but there is a point where you are better off getting two subs instead of pumping more and more power into one sub. For example, instead of putting 1000 watts into one sub, it would be more efficient and much louder to hook up 2 subs at 500 watts each. You need to double the wattage to get a 3 db increase. So you reach a point where doubling the power becomes impractical and you are much better off just adding another sub.

 

It has to do with when a sub reaches it's linear excursion limit. After that point the increase in SPL becomes compressed. If a sub can reach it's limit in a particular size box with 275 watts there is no point in getting a bigger amp. It's important to look at the sub makers power charts to determine the box and amp you want for the sub.

 

how do you know when a sub have reached its xmax at a given wattage?

 

If you use your ears you will start to hear distortion instead of music. Most people are so used to the distortion that they think it belongs in the reproduction. Probably the best way for the layperson is with shareware such as http://www.linearteam.dk/ WinISD Pro. Basically there is a point where you turn up the volume **** and the difference in SPL is not as great as the prior similar increase on the ****. That is when you know that you are reaching the physical limits of the sub, box, and amp combo.
