Just a question Sadistic. What school did you learn this from?

thanks again ... i still dont see how he is hooking up the outputs tho ... is it positive inside negative shielding? how would you do this with you high level outputs

you got to remember dc flow from plus to minus

Only problem here is music is alternating current. If you have DC going to a driver, you have a cone stuck in one direction which = zero sound being produced.

one problem there your kinda wrong

it's switched dc not ac man big difference. it's switched buy a triggering voltage on the amplifier chip it self. you are right if you got a full blast of dc threw the chip your speaker will do just what you said = zero hertz.

Which is AC. It is alternating, just in many cycles instead of at one cycle.

wrong again alternating current power etc.. flow's in two direction's in a conductor there is the positive cycle and the negative cycle if the power never drops below plus or minus 0 volts it's d.c. if it goes negative then positive then it's ac.

so what fine school did you get this load of crap from any ways.

So what you're saying is that an amplifier puts DC out the positive lead to the sub, then switches and puts DC current out the negative lead to the sub to get the sub to move back in?

Have you ever put an Oscope to an amplifier's output terminals and played a sine wave? The wave does go both above and below the 0 reference line.

In the videos disconnecting the speaker wires seems counter productive to me. When I adjusted mine with a scope I left them connected and went through tracks containing 20hz to 60hz in 1hz increments. Doing that showed that while at 25hz it wasn't clipping but if I went to 30hz it was and I was able to correct it so that no tracks were clipping.

that would be ac that switches directions. but dc has a different signal pattern altogether saw square waves etc etc ... if seeing the sine wave on the o scope go below the zero mark when dc sine waves are used you have the meter set wrong.

So then how does a subwoofer move in after the "DC" moves it out? Having 0 DC current would move it back to rest, but then how does it get the sub to move backwards physically, more into the motor (like when the coil hits the back plate during overexcursion)?

Just fyi, electrons always flow from the more negative to the positive.

Your terminology is confusing. AC by default includes a frequency and DC is current flow in a constant direction. ie, there is no "signal pattern" in DC. There could be an outside source (switch) that forces the DC into a pattern but the DC cannot be described to have this pattern. When you say DC sine waves, you are confusing the situation as there is no such thing. DC by its nature is constant flow.
