my 20.1 is 86% but its at 4 ohms????

Bet its alot lower at .5ohms........lol

my hifonics is ~70%

169 max amp draw for 2000w

amps with regulated power supplies are often even lower, even class D ones, but it's worth it if you can feed the beasts

i plan on going back to a regulated amp soon, i'll deal with voltage drops

so do less efficent amps un hotter, but wasting current draw, and disbursing it as heat?

Usually only true when your at the higher ohmage law.......not at the lower ohmage thus higher current demand.//content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif Thats when amps like JL Audios will **** current like a a/b amp and kill a elect. system.Now at the higher 4 ohm loads they are very effiecient amps and very clean though.

Yes pimp heat is bad unclean wasted efficiency. aka.............VIPER

hey man my viper amps treat me nice.

Find my Birch wood yet

sure it wont be that difficult.

how do you want it to be finished anyway>?

Whether or not they'll actually run "hotter" is dependent upon the amplifier's ability to actually dissipate the heat (some amps are better at heat dissipation than others). But yes, a less efficient amplifier dissipates more energy through heat.

Think were were gonna keep it simple and go ported 2-2.5 each with around 80-90sq port area tuned to 35 and then do something with the bat and amps maybe a amp rack of some kind. Cant find a matchin mid high amp yet so that sucks.Guess Ill have to wait till some arc XXK stuff shows up and grab it.

Didnt need neon lights back then did he

lol

thinking of going the IA 20.1 route, but dont feel like dropping the coin for the same power.

Im hookin mine up Monday.

Ill call you then and let you know how it goes.

It is small for what they say it does.

Well see how it likes .5 on 2 L7s..............//content.invisioncic.com/y282845/emoticons/up2something.gif.dd110ecf3ae4b76050d87598f2f8de7c.gif

The Md2 was OK but a lil Muddy at .5 like the Damping factor wasnt too good droppin it that low so well see how this is.

They say 2600 at .5 with the 20.1

MD 2 was 1900 .5 so Ill see

we will see

then sell it to me.
