I have a 1 farad cap and I just bought a 3 farad cap. I was thinking that 4
farads is better than 3 for my system, but has anybody wired two caps
together, if so, series, + to + and - to - ??? Thanks.

Parallel to sum capacitance.  Series would result in less.

yes but you might have trouble hearing your stereo until after the
explosion.LOLL.....
LOLL=laugh out loud loser!

Yes, I use multiple caps and you just connect them in parallel.  If you are
using the large electrolytic variety (looks like a huge "D" battery) they
make buss-bars that enable you to tie two, three and even four caps together
in a row.

Yes you can. But keep in mind that your ESR goes up as well...

That's funny, I had always heard the OPPOSITE (from people I REALLY trust in
the industry), that it was better to use multiple smaller caps for PRECISELY
that reason (oh no, here we go again!).  Perhaps someone else could chime in
on this, I would really like to know.

Ah yes, you're correct. Connected capacitors in parallel will lower the ESR
slightly, and connected them in series will increase. Thanks for catching
that.

Les.
