Stereo Amplifiers, Will they power HHO Generators and control Heat?

Will audio amplifiers work to power HHO Generators on vehicles to control over heating of the cell? If so what other parts would be necessary?

you don't want to go with Vdc you need to go Vac as this will control the voltage input(less current draw) and the heat, also you will need the frequancy of Vac to increase HHO production, please do more research

Lots of car audio amps specs are very misleading, I've seen 1000 watt amps with 10 amp fuses, the math just doesn't work 120 watts in and 1000 watts out ... So they may very well work, but why not use a simple DC to DC converter and set the current / voltage to level that doesn't overheat the cell, and also install some form of a overtemp shut down, even if it's a snap switch and a one time use thermal fuse, like a coffee maker.... There is lots of DC to DC converters, and some nice cheap ones are commonly found in laptop power adapters for automotive use, I just got on from rat shack and it outputs between 12 to 28 volts at upto 4 amps and it was under $20 ....

You got that right, even as RMS that doesn't work...

I've got a 200 watt amp in my car, which I max out all the time with my mp3player (it's pretty tame.) If I stuck my 30 watt Ampeg tube amp in the car and cranked it up, blood would pour from my ears....

No blood, but you might let out the magic smoke contained in most car speakers, they tend to follow the same ratings logic as the amps... My favorite rating is the commonly used P.M.P.O. ratings where they take the RMS rating and multiply it by 100 and they forget to tell you that is at 1 Khz for .5 of second with no more then 20 % distortion... But I guess driving a 12 inch speaker in free air is easy, even if it doesn't sound correct......

heh heh.

Here's an interesting discussion on Electronics forum, the usual tube vs. solid state wattage debate. Believe or don't believe, wattage ratings are screwy for modern amps.

But I guess driving a 12 inch speaker in free air is easy, even if it doesn't sound correct......

Which is exactly the situation for a 45 year old tube amp--driving hard a 15 in. speaker designed to distort the tonal range (in a specific way), in a large resonant cabinet is a very different thing.

Tube vs SS, Tube wins hands down, even if you build it on a cake pan, they look better... And when you compare driving a 45 year old 15 inch speaker you need to look at the efficiency of the speakers back then, I will modern speakers are a much better when it comes to this, even if the car audio one are questionable.... And I guess I should get back on topic, what about using an inverter and small transfomer for your HHO production, most inverters will deliver there rated outputs, well my 1000 watt Xanterx inverter will power two 500 halogen work lights, and most inverters have temp senors built in them to shut them down and you could just add to then.... (( And by the time you price the fet's and heatsinks you can't build an inverter for less then you buy on at the store for, and watch at big box stores they always go on sale, i seen a 400 watt go for $25 last week, and my 1000 watt was only $75 ))

My point was that the tube amp and the speaker were designed to work outside of the linear range (they sound their best outside that range), but most s.s. amp are designed to minimize distortion.

That might explain the inflated values--the solid state amp is rated for transient spikes it can't possibly maintain, and it's normal "polite" output range (low distortion) is much lower.

Push the tube amp to distort, and (if it's designed right) it will respond with 2nd order distortion, which adds to the loudness, but is fairly pleasant. Transistors don't do even-order distortion, and start distorting on the 3rd harmonic....

my own tube amp build should be posted here within the week...

Can't wait to see it, I was just starting to dabble in the tube amps, even after getting told off by a real old timer, that I shouldn't know what a magic eye tube is, I guess I was the first person to walk through his doors and ask for one in forty years, and he didn't have one, but he is going to find me one, only because I asked nicely and I think he's surprised some one is showing intest in some thing that has been made obsolete nowadays .... I was going to use it for a vacuum tube VU meter for the AMP...

'Magic Eyes' are cool. I even think they still manufacture some (Russians or Chinese.) Would make an awesome VU meter... I'll PM you the project--I don't want to publish until I get some decent video of the amp (and my chops aren't real good right now...)

Mmm, I'm not getting it. If the audio amp is powerful enough to separate the water molecules, why wouldn't overheat like any other source? And what's wrong with monitoring the temp, as NachoM suggested? Or limiting the current, for that matter? Audio is AC, so if it's important to keep the O's and the H's separate (say, for pressurization), then it's probably a bad idea...
