That's pretty sweet. I have a kicker zr1000 in my neon.

Then check this out.

I wonder how many alternators they had to install. If I turn the gain
up
on
mine I lose tons of horse power.



Horse power and wattts can be converted in a linear equation, all you
need
to know at this point is the efficiency of your amp and alternator. My
old
rig pulled 11HP, haven't calculated the new one but the sub amp is
digital
and WAY more efficient. it will beat your head on the dash and I still
have
yet to see it pull more than 25A.

Those "digitial amps" are really called class "D" and they can range from
90
percent or better in efficiency.

To make it even more confusing they can also be called class T because a
certain company, tripower I think, makes a proprietary one chip wonder
driver circuit. same operation different name. I prefer to call them
switchers

I have an application note in one of my National Semiconductor data books
for a high speed comparator chip that shows it being used in a switching
type amplifier. Its a real simple circuit believe it or not. The design used
bi-polar power transistors for the output. Now you can buy complete high
power switching amp chips from several vendors with outputs up to 100 watts
in some of the ads I saw. I don't use them for any designs I do so I don't
really pay much attention to who sells them. I would assume that doing an
Internet search would turn up some of vendors.
