2 required (one each for front/rear).
Hooking up a separate sub without a dedicated sub output on the head unit
will be ... interesting ... unless your amp has a passthrough feature to
feed another amp for the sub. If you have been feeding ONLY the sub from an
amp you may now have to go to feeding the mids/highs with an amp (with a
passthrough port) to keep the sub.
Brian is right, no cap needed where you're at in power requirements. When
the amplifier needs constant voltage at high amperage (more than the
alternator can provide --- 70+ amps with the alternator already feeding
everything else) the capacitor provides the juice. When there is no cap for
a big amp you get things like flickering lights, stuutering ignition, and
batteries that die quickly because the stereo hits them for the extra power
and they are not designed to have high amperage drwan from them in short
bursts. Adding more betteries can help the "dying battery" syndrome because
they each get only part of the extra amperage drawn from them when they
take a hit. But it still causes flickering lights etc. because it grabs
from the alternator output before the batteries when the alternator is
operational.
If you go the route I did then you might want to add a cap to save the
battery from taking extra hits (stereo separate from main wiring on a
dedicated aux battery). With one of those orange batteries my stereo would
last for 8 - 12 hours at reasonable volume (Family reunion '06). With the 4
I have in there it was still going strong after over 24 hours at
"unreasonable volume" (T4P). I have a 1600 watt amp on the subs and a 200
watt amp on the mids. I want to add a 50 watt amp to run separate tweets
and take the highs out of my mids. Of course, you can always buy one more
battery from me to get extra run time <grin>.
