Do you add Receiver + Amplifier wattage?

Never. If you use high side inputs on the amp, it knocks that signal down to a usable level basically eliminating the amplified signal. If you use RCA's, they are line level (not amplification) leaving only the amp output. However, if you use the deck to power some speakers and the amp for a sub, then some competitions require you to add them for rules reasons.

I was at an IASCA event in Dayton OH back in 97 where they asked him what the stock HU output was and added that to the sub to determine what class he went in. It was a Jetta, so he said something like "16 watts per channel i think" lol.

Wtf?

In the mid-late 90's I competed 0-150 with 3 50 watt RF power series,  and  151-300 with 2 100hc's and 2 50watt monoblocks.

Iasca never counted deck power out here in the 4yrs I competed, of course I haven't used deck power since the mid-80s... those were the days..."Kraco power"...  :wow:
