Check your battery connection again. Check your alternator. Check the fuse
connections. If your problem is that severe then something else has to wrong. 2
farads of capacitance are not going to actually SOLVE the problem if its that
bad.

The same system had the same reaction on two seperate cars. Maybe I need
to run a dedicated ground or something.


Because physics doesnt change depending upon the setup. The numbers tell me
things. Our ears are easily deceived. Go back though what we talked about and
look. The numbers tell me certain things. I dont doubt that you percieved
certain things. But you "heard" and felt things that are below the threshold of
hearing and touch. Pychoacoustics, study it.

I understand what you're saying, but my main results are not the seat of
the pants kind. Before caps my voltmeter (the one in my MR2's dash, as
well as a seperate DMM) showed a substantial (1-2 volt) voltage drop at
each bass hit. After installing the caps that drop was signifigantly
reduced, to the point that I had to TRY to get any drop out of it. I
wouldn't try to argue just on a seat of the pants thing... I've heard
too many people say their air filter made their car feel faster to try
to argue a point like them.
