Hello for everyone,
I have recently developed this 4 channel module based on LM4766, I have already a module for powering up a subwoofer mid and high's but don't have enough power for powering up an 8 inch sub only good for about a 5 inch subwoofer.

So I develop this module, it's outputs are configurable as 4x50; 2x100; or 2x50 more 1x100, I would like to know if there more people interested on this and if there is someone that know a good power supply SMPS running on 12V that produce +30V -30V to use in car áudio?
In the worst I develop my self,Regards

Hello for everyone,
I have done all the testing with this module, I created this post for the people that would have interest in a 4 channel amp module.
I wanted to check if someone knew a good smps from 12V to plus minus 30V in order to use this amp in car audio, until now no one
mention any, and I will develop in order to use this amp module for car audio to use for myself and to other diy people.
On this module, it's outputs are configurable as 4x50; 2x100; or 2x50 more 1x100 Watt making it suitable for Hifi stereo,bi-amplified speaker system or multi-channel.All channel are free of noise "no hiss" very clear sound.
On the example pictures shows that with the optional trimmers which were applied on channel 3,4 the output offset voltages can be adjusted near to zero, without trimmers on channel 1,2 the output offset voltage was around -4mV.
I have listed this module with both isolated and non isolated IC's at my page if you have interest you can check here:

You have some strict requirements, so finding an SMPS to go from 12VDC to +/-30VDC may be difficult.
Meanwell makes a 100W single SMPS for 12 to 24 VDC (adjustable to 30 VDC). SD-100A-24
IF it's possible to connect two of those in series for +/- 30VDC, that could potentially work. I would get more qualified power supply expert recommendations first, however.
