T-amps in the car. 41Hz Amp1 for the tweeters (Vifa XT25C90-04) and Amp2 for the Mids (Focal Polyglass 165V2S)













they only need this much heatsinking.

Hi all

Made this because I wanted to know how much power I actually needed. Turns out 15W will push my full rangers well into distortion.

The case is one from e-bay. £2.50 each. The plan is to make a buffered pre-amp, but for now, I'm using the PC volume control

Notice the heavily oversized heatsink, and heavy-duty carry handles.

Here's my diy Class D amp. It's based on an reference design of irf ( IRAUDAMP7D) together with three TAS3103a DSP's for sound processing (active crossover, volume control, equalizer, surround effects, spectrum analyzing, ...).

What started as a school project became a long term project. It's still under development.

current setup :
- 6 channel class d amp, 300 watt rms/channel into 4Ohm speakers.
- 4 PCM1802a ADC's
- 3 TAS3103a DSP's
- 1 6 channel PCM1606 DAC
- µC PIC24HJ256GP206
- 2 oldschool vu - meters with rgb backlight
- 1 240x64 pixels graphical LCD screen (blue blacklight)
- self made rotary encoder (old ball mouse hacked)
- 1KW transformer with 6 x 10000µF caps

future plans :
- rewiring the unit (little messy now)
- replacing PCM1606 dac by DSD1794a
- adding s/pdif receiver for digital sound.

Excellent design Kaasari!
Is there vent opening under the amp?

Just to get my shiny new Connex Electronics TA3020 v3c module audible safely I've quickly cased it up in a discarded industrial power supply case I found. I was even able to re-use the "hospital grade" emi filter and a lot of the wiring that was left inside.

This is just a "get it up and running" build. still need to add power leds, standby mode, on/off switch, shielded input cables and other assorted frills.
