no my speaker moves from the sinewave bass frequencies! I can totally see it and I can feel it in the walls of my house too.
the speaker pops out just slightly when I plug it in but that's only that... when I play music my speaker moves a LOT more whenever I play a bass heavy song
It easily moves half an inch from the bass frequencies alone. maybe I should just upload a video and put a link showing my subwoofer moving from the bass frequency sinewaves so you know im not faking it or something....
it's real! i'm not joking my subwoofer really moves this much!
and I still get amazing sound quality too. it only moves a lot when I have the 12 volt power supply hooked up..
when I hook the 5 volt power supply its about half as much but still pretty loud and clear and it doesn't get hot with the 5 volt power supply.

I believe it moves a lot like you say

Its surprising how little power you need at home, and if you haven't already seen it,

A Test. How much Voltage (power) do your speakers need?

Hi,

Is in post #22 and #41 in as plain point to point as you could wish.

rgds, sreten.

Please stop pretending your circuit actually works properly or does anything useful.
It doesn't, and you won't learn anything pretending it does. Reality is reality and bites.

Ah, the old subjectivist-objectivist debate again...

i'm wondering if there's some way I could increase the watts going to my amplifier... to get louder sound.
how would I do that without changing the power supply?
a capacitor a transformer and a DC to AC converter or something?
not the ones for 12 volts i'm talking about something that simply generates a pulse from on to off so I can get AC from the power supply
then the capacitor will remove the background noise and change the AC to DC that is coming to the speaker so it doesn't make a hissing sound or buzzing sound
then will I somehow get more watts?
or am I wasting my time asking this question?

Seriously, bro. You're demonstrating that you haven't learned much, if anything, six forum pages in. And worse yet, you seem to refuse to. So much is wrong with that last post that this may be the only reply you see.

It might be useful to those trying to help if you give a quick background of your electronics knowledge, such as your age, education and specific interest or projects you have done.

Thanks

Hi,

Your wasting your time asking questions you don't understand the answers to.

Loads of info here : Transistor

The next step is two transistors with feedback to set gain :

Click the image to open in full size.

A = (R4 + R5) / R4

But your still a long way from an efficient power amplifier that will
make the most of of a limited supply voltage or using bridged.

rgds, sreten.

I don't have enough resistors that are the correct values to make it like that
I only have one resistor that works perfectly the way it is.. maybe I should just get a transformer or something

also I'm only 15 years old and i'm home schooled at www.k12.com and I don't know hardly anything about electronics except how to wire something together to make it work... I don't know how to read a wiring diagram unless it shows exactly where every wire goes to the correct end of the correct component and which end of each component goes to the correct end of the other component..
I have no clue how to read a diagram if it doesn't state exactly which positive or negative or where which positive or negative wire goes where.
it's not like I can just look at it and guess which wire goes where.. I wouldn't even know where to hook the output positive and negatives to. or even where they are in the diagram..
I would need an image taken from a camera with labels showing which end of each wire is positive or negative and where it goes to which other end of the other component
then I could just make it look the same already knowing which end of my components are positive or negative and connect it the same way as the picture.

and if everyone is just going to hate on me just because I don't know something that you think is simple then I might as well have never asked in the first place.

Everybody on here started off by knowing zero about the subject. In fact I remember my very (very very) first attempts at electronics. Canibalising a little 6 transistor radio for all the parts and trying to cobble an amplifier together. Identifying transistor connections was a problem because I didn't know how to do it. And those arrows on the emitter (why did some point in and some out). I remember building a headphone amp using a single AD149 which seemed to need at least 20 volts to work... and understanding biasing... whats that.

But... I wanted to learn though and in fact learnt very quickly by my mistakes and by reading all I could get my hands on. And thats something we all hope you will do if you are interested. With todays technology a saying of my old boss comes to mind... "you've never had it so good". I used to cycle 40 miles round trip to a component wholesaler for a few BC107's or some resistors and caps. Always getting all the books I could from libraries and so on.

You have more help and people willing to help on a forum like this than you probably imagine... but you have to help yourself too
