Stetsom Amps

[tommyk90]

that shows the 26kd out burbing 2 sundown 1500d's just useing the watts as a comparison thats 3000 outs sundown so how is the stetsom louder with less watts?

Did you skip over the part where the 2K6D drew more current?

Besides, .1 dB is pretty negligible for SPL testing. Unless the test car was super consistent. I can lose/gain .2 dB between two burps that are 30 seconds apart.

Also, the stetsom drew more current than it was rated for?

while looking at this 7kw's guts, them are pretty tiny.. I looked into stetsom a while back ago, and I just cant imaging these hanging on too long for daily abuse.

ive been bangin on my for a year and a half!!! in my everyday car!!!!! and i only know 2 settings loud and OH MY GOD

soooo whats a long time for these amps to hang on??? cause i aint stopin!

how about this if i burn one or see one burnt! i know alot people with them ill post it how about that

Well, given that it would take at least ~220-230 amps to produce upwards of 3kw at 14.4 volts, using 4 gauge wire would be completely out of the question. 140-150 amps is the stated limit for most 4 gauge wire, thus why most 4 gauge wire kits will only come with a 100-150 amp fuse at most.

Which makes a lot of sense since the 2K6D has a 175 amp internal fuse.

Obviously, as the run gets longer the less current it can safely carry. And vice versa for shorter runs. But I still wouldn't try to pull more than 200 amps through a one foot section of 4 gauge.

I understand the wire runs, but how much could you cram into the input before it melts off the board? I would think if you have say a 1 foot or less run of 4G, how many amps could you push through it before it fails?

Would amount you could push through the input and the % over what a fuse could take = the output that people are claiming from the amp?

I can see that it would be a little more then anyone would want to push on a daily limit, but then again I really don't think people are pushing big power amps all day with out failures no matter the brand.

Good question. Honestly, I don't have an answer. All I know is that if I'm expecting more than 1500 watts out of an amp, i'll be using 1/0 for sure. Better safe than sorry.

For a one foot run, you could probably pull upwards of 200 amps out of it, but thats really risking a lot. There's really no sense in risking burning your car down/burning equipment over a little piece of wire. You're better off getting some 1/0 and trimming it down to fit into the terminal.

I've seen plenty of people run upwards of 5kw on a daily basis with no failures. But those amps also had at least one set of 1/0 inputs.

As for the fuse, you could easily pull double the rated current through a fuse before it blows, but that's not really saying a whole lot for a daily driver setup. Most fuses can handle double their rating for a few seconds, enough to get a test burp off, but not enough to get that power out of the amp on a daily basis.

Now I've heard of people removing the internal fuse to get more power, but thats something I would only advise for competition purposes. Definitely unsafe for daily. Unless you have an inline fuse a few feet from the amp.

good clean discussion, please keep it that way, and it can continue till your blue in your faces, please dont bash, please be nice.

please educate.

Hey thanks Jack, i 'm also going to look at different batteries like the cs9000, i also have some new stuff up my sleave, that's if i can go back to my truck and work on it, too many g-14 builds i should of never told people i can weld, DOOPE i Didn't again

Ok so say it's conceivable that you could get the all the power you needed into the input, then even less FET's then the other guys you could see the power they claim? Then If you assume their not using junk parts, it could stay together? Better parts could take more abuse?

Then take the 7K that is 2 boards now they have stepped up the inputs to 1/0 then the power wire on the inside was also stepped up, It would be safe to say that the 2 are getting a safer power supply then the 2 singles?

Wouldn't the 2 boards have a better time supplying power and sharing heat thus making it more efficient? and stronger? I've been reading like a fool tonight on the different types of amps and the class D is starting to see as much as a 95% or more efficiency

I'm actually more happier about my 157.2 than my world finals # because i could only get a 155.5 with the 2150, and know i'm louder with the same battery by testing and opening my port a little.
