A good observation, take on of those big strips and wrap around the manis cable just on the inside of the cabinet/enclosure.

And those chips, do they not need heatsinking ?

I have a switch with remote control in the power outlet.
That one do have a main fuse.
You can`t see it on the picture.
But I will fasten the power cable better.
The chip have an internal cooling and don`t
really need one. It doesn`t get hot at all.

frebar, why no heat sink ? YOU should put at least a piece of metal on there just incase they do get hot. Better safe than sorry with smoking woofers.

Default My First Chip Amp

Here is an amp I built for my son with his band's logo on the top panel. I used pcbs from chipamp.com. Purchased my own components otherwise. Very happy with the results. Will be used in an apartment system using some very nice Signet bookshelf speakers and a powered 8" sub. Strictly CD based with a decent player.

Custom paint was done by www.mccallcolors.com

Thanks, I'm quite happy with it. The pictures don't really do justice to the depth and effect of the paint.

my new and more compact amps. A pair of monoblocks with a opa549-chip in each along with a 120VA transformer running 33VDC, a few volts above recommended maximum but it seems to work.
