Diy Solid state amp, designs

[AndrewT]

if you bridge a 1500W into 8r0 amplifiers it should if designed and built properly deliver 3000W into 16r0.
If you connect an 8ohm speaker to this amp and ask for full power this will be roughly 5000W into 8r0, if it does not blow up first or burn out the bank of speakers giving you that 8ohm load.

Andrew,
We are talking about bridging 750w/4 ohm amplifiers, and using that bridge into 8 ohms.
We are not talking about bridging 1500W/8 ohms ones.

1500W from a class AB amp is insane. You will have too much heat to deal with.
Get a professionally made Class D based amp for this job.

Hello all i am looking for hi power amplifier designs or sites that have instructions on designing a High wattage mosfet amp either with high rail voltages or using bridgeing and parralleling of amps to drive upto 500watt @ 2ohm

the schematics of post #40 about
http://www.diyaudio.com/forums/soli...tor-families-audio-power-output-stages-4.html
will give you some inspirations

i am talking about 1500w per chanel in to 8 ohms and jst to clarify if iv got a ,bank of 4 500w RMS speakers i could drive 2000w RMS in to them.

Which particular use these amps and speakers are intended to?

four separate 500W amps will give more reliability than one amp.

i know and that probably what ill do but could i do it without cooking the speakers????????

There are some interesting amp modules on ebay from a company calling themselves "Class D audio" (I think that's right) They are not class d amps but they do offer a range of very high power amp modules, some of which have heatsinks already attached and some have integral cooling fans.
They use their own lateral mosfet output devices which they make great claims about.
Might be worth considering a look for the power you are looking for.
Just a thought.
(they are on the "power amp" pages under "Home audio and Hi-Fi")
