Aluminum has almost 1.7 times the electrical resistance of copper... nuff said...

I'd have to assume there are reputable maunfacturers (wishful thinking perhaps). The crap I see advertised is surely misrepresented. You MUST have a large power supply to put out watts, plain and simple. Switching PS's sorta work, but for AC only (naturally). Big PS, big caps are absolutely needed to keep the rail voltage up. If rail voltage sags, so does output. I certainly sense you're "fishing" but I'm an old fish.

The reason car amps don't need large power supplies is because they switch in the Mhz range.. anything that plugs into a wall requires significantly larger transformers and filter caps because they need to rectify a 60hz signal..

I can show you numerous car amplifiers that are capable of producing as much or more then your 96lb amp and weight a fraction of that...

An electrician like that Tron guy from the Chi? //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif

This is the guy who said my bass amp should be putting out less than 2VAC //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

tron from chi??

wtf is you is talking about?

and apparently a run of 1/0 all the way around THE WORLD would carry just as much as a 1" piece. news to me //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

meh. i'm going home //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

fck a terror-tron from chi. unless he has beer, i'm not searching for him

or joose. if he gots teh joose, i need to find him

Then consider yourself educated. Length has NO EFFECT on ampacity, only voltage drop. 1/0 copper has a resistance of .122 ohms/1000'. If you have 25' in your VERY long Honda, that's .00305 ohms. At the wires maximum capacity of 170 amps (260 amps is only allowed in free air) you'd get a whopping .5185 Volts dropped over 25'. Most vehicles arent that long, neither are most garages. Not to mention you'd actually have to draw 170 amps. If you have a piece of identical wire 1' or 1 mile long, they're rated for the same amount of current. Each will melt at the same current flow. I'm sure you're aware of Google? Try "wire ampacity" if you still don't believe.

Interesting theory. I am more than familiar with switching power supplies, I'm pretty sure I'm using one right now. They work great on AC as they essentially "chop up" the sine wave and rearrange it You seem to be missing a very important part of the overall equation though: the order of magnitude difference in supply voltage (120 vs.12). Rectifying 120 vs. stepping up 12VDC to achieve adequate rail voltage requires some VERY different things. I've never heard of people adding large caps to their home stereos, because the amp's power supply is adequate already. As for car amps putting out more than mine, they MAY exist. You should call the concert promoters and suggest they use car amps at all their venues. The roadies will love you for saving their backs.

i'm obviously not an electrician //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif

and my amp probably only does 200wrms (if that) //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif//content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif//content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif//content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

You don't seem to have any idea what you are talking about here, so please spare us your banter.. //content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gif

A car amp is able to switch 12v in the 1-10mhz range then step that voltage up and rectify it using very small components compared to an amp you'd plug into a wall which transforms and rectifys a 60hz signal.. WHY? Because the transfomers don't saturate with the higher frequencies, and smaller filter caps are required..

If you can't grasp that concept then I suggest you stick to being an electrican and not worry about anything else..
