Thread: 800-1000watt amplifier schematic?

ummmm... how are you planning on hooking these speakers together. series, parallel, combination? you are going to have to plan very well to get the right impedence rating so that the amps are not overworked. powering speakers at low impedence is going to require one hell of an amp...

underpowering speakers so the amps clip? all underpowering a speaker does, is result in not utilizing the full power handling capacity of the driver... are you talking about overloading the amps because the speaker load has too low of an impedance? someone please enlighten me.... i feel like im missing something...

side note... if you are doing this to **** off your neighbors.. i really dont want to take part in this... seems like a HUGE waste of money.... especially since you have always put up the image that you dont have a lot of expendable income laying around...

whatever... i dont know why im wasting my time responding to this thead... but since i already typed it out...

There are more effective ways to **** off your neighbours...And cheaper too...

technically he is correct (its a first i know!) since by driving the amp too hard (making it 'clip') in an attempt to get full potentional from overpowered spkr, the amp ends up outputting a near pure DC signal which is NOT very good for speakers...

I have read this quite a bit on some car audio sites/audio sites, but have never experenced it myself.

I think we should close this topic now, just SB on one of his go-nowhere pipe dreams again.

for these pesky neighbours, what about lighting a bag of 'dog poop' on their front doorstep - like Adam Sandler did in Billy Madison? He even got the girl in the end!

Nah, nah, nah.. I just wanna PI$$ of teh neighbours.. they had this loud music going at 2am.. and, I was TRYING to sleep.. So.. payback time...

Have you thought about renting a sound rig? There not to bad price wise.

And you can cover the cost of the rental by having a party later in the week.

This only happens if you run the amp at full power and the amp starts to distort, if you keep the amp running under 75% you get no distortion and no damage to the speakers.

Note: the above is only true if the impeadance of the amp is the same as the speaker bank, (but then that's what you want for max efficency)

Note2: If your running the rig above 75%, then you need a bigger rig

alright, i do understand that concept.... but he did write UNDERPOWERING the speakers will make the amps clip... and that is what i was confused about... i know that if you try to push too much through the amp it will clip, but it was the underpowering comment that really threw me off... perhaps a typo, but then again, the whole point of his post was that he didnt want to underpower them b/c that would cause the amp to clip... so i am leaning away from the possibility of a typo and more towards SB/MP3K not understanding what he is talking about....

unless im still not getting it...

~mike

edit... okay, im done confusing myself.... underpowering, as mp3kid puts it is running an amp that is too small for the rated power of the speakers, and then turning up the volume too high to account for the lack of power in the amp... thus clipping and distorting to high heaven, until you either fry the speakers, trash the speaker surround foam, or rip the cone from the coil...

i think im going to stop over thinking.... ouch.. that last thought hurt my brain.... oh well, back to work

My neighbors across the street were playing the radio way too loud last saturday. It's always anoying until they play a song you like

Anyway right then I really wanted to have this:
http://northcountryradio.com/mpx2000.htm

I think it's about $80 for the kit.
Then I could just Hijak the radio station they were listening too and pump my own mp3's onto their stereo!

Pluss it would rock for those long sumer caravan rides. You could share your music with multiple cars!
