WOW...
That is one hell of an amplifier.
It's nice to see an amp with actual speaker terminals and quick power disconnects. Nice touch.
What are the specs on that lovely lady?

Looks like one very well put together amp. What are the specs on that work of art?
And when are you hooking it up for a sq review? Like that amp a lot just from it's looks.

Specs/info and components used are listed below:

Or for those that dont want to click..
Components
We decided to dedicate a separate page to list and to deepen with right importance, all the efforts we carried out to look for the best, the most reliable and the most expensive components nowadays existing on the suppliers world-wide market.
" No other Car Audio manufacturer has ever made widely use of these Top brand and Company in the electronic components category."
1. Class A input preamplifier fully made with Siliconix© jfets, only Wima© "MKP4" polypropilene capacitors on signal path and input wiring with Monster Cable© "Interlink 300MKII".
2. Voltage amplifier totally made with MIL-JAN grade full class A complementary bjts, with auto-regulation of thermal working point.
3. Output devices are IR© complementary mosfets, each capable of 180W and continuous 21A.
4. Capacitor bank close to output devices is ultra fast and low-ESR, capable of 42 Joule (VA210) of immediately available energy.
5. Output wiring speakers by Monster Cable© "OMC".
6. Power supply wholly built with Magnetics© MIL-GRADE ferrites, United Chemicon© low-ESR capacitors and IR© power mosfets each capable of continuous 110A.
7. 24K gold plated copper with high thickness tracks Printed Circuit Board (top grade FR4 material).
8. Thermal dissipation by internal cooling tunnels, integrated and thermoregulated fans.
9. Battery supply connectors are Anderson© "Powerpole 80A" for 0.0002 ohm max contact resistance.
10. Chassis made by CNC and Laser cut machines, hand brushed natural aluminum, fully inox screw bolts.
